We look back over an eventful 2010.
It all began with probably the worst and most
far-reaching financial and economic crisis and ended
with a strong boost to the economy that nobody
would have expected. Now we need to stick to our
guns and continue to drive forward at full power so
that you can continue to do business successfully
with us in the future. Read about the innovations
and improvements that will help us to pursue our
trend for growth in this edition of Airmail.
Energy efficiency is the hot topic for the whole industry. The new IEC 60034-30-2008 standard
that regulates the statutory minimum level of efficiency for electric motors frequently plays the primary role in this. However, did you already know
that there is far greater potential to make savings
on blowers and side channel blowers that run at an
optimum rate? This is exactly where we fit in with
our knowledge and expertise - please feel free to
contact us!
We have also optimised a few of our high-pressure blowers and the result of this is the BOOSTED
range - our new high speed blowers. They combine
even higher pressures and greater flow rates with
an improved level of efficiency.
The human factor plays a key role within our
company besides the development of new products and accessories. Both you, as customers, and
also our employees are vital elements in our daily
business. This is why we carried out our first professional customer satisfaction analysis in June of last
year. The results were very gratifying but also showed us potential for improvement. At this point, I
would like to thank you for your praise, criticism,
suggestions and requests - invaluable knowledge
for us that you too will benefit from as our partners.
Finally, I would like to sincerely thank you for
our good working relationship, constructive dialogue and mutual trust. We would like this to continue in the year ahead and to maintain the regular
exchange of ideas.
By the way, why not visit us on our exhibition
stand at the HMI in Hannover from 4 to 8 April
2011. I will be there for the whole week and would
really look forward to a conversation with you in
person.
And now have fun and enjoy the read of the
new edition of our Airmail.

ENERGY
EFFICIENCY
Do you already conform to IE2?
The countdown is on - the new standard comes into effect on 16 June 2011
T
he International Electrotechnical Commission (IEC) has developed and published a new
standard in order to reduce the global energy consumption and, consequently, the CO2
emissions. The „IEC 60034-30-2008“ defines the levels of
efficiency and efficiency classes on asynchronous motors at
50 and 60 Hz at a capacity range of 0.75 kW to 375 kW and,
consequently, replaces the different national regulations that
have been in force up until now. From 16 June 2011 onwards
only motors that comply with the standard, i.e. that meet a
minimum of efficiency class IE2 at this point in time, will be
allowed to be placed on the market within Europe.
The EISA (Energy Independence Security Act) has regulated the new minimum efficiency level requirements for NEMA
motors (60 Hz) within the North American region since December 2010.
Blowers and side channel blowers are also affected by
the changeover
It‘s not just manufacturers and anyone purchasing motors
that should find out about this new standard as quickly as
possible and include it in their plans. A considerable number
of components that are operated with an electric motor must
also be fitted with motors that comply with IE2 by 16 June
2011 at the latest.
Therefore, motors for lots of Elektror blowers and side
channel blowers, with the exception of a few, must also be
changed over to a minimum of energy efficiency class IE2 in
accordance with the standard. This brings substantial benefits
to our own motor manufacturing, such that we have already
been supplying all Elektror devices with IE2 motors for a few months.
The earlier the better
In order to avoid bottlenecks in processing or supply shortages, a changeover should take place as early as possible particularly on projects with a longer duration. For example, in a
few cases the external dimensions of the devices change and
Elektror must then check to see if an alternative solution is
possible by using a different Elektror device or if it is necessary, where applicable, to adjust the design of the mechanical
engineering company‘s system.
Those not affected by the standard:
• Blowers / side channel blowers with motors
< 0.75 kW and > 375 kW
• Pole-changing devices
• Single-phase devices
• Devices that can only be operated with
frequency converters
• ATEX blowers
The issue is more controversial with blowers and side
channel blowers that are built into systems that are exported
to the USA or Canada and used there. If these are fitted with
foot and flange motors, they must have already been fitted
with NEMA premium (=IE3) motors since 19 December 2010.
NEMA energy efficiency (=IE2) is acceptable for side channel
blowers and blowers with flange motors without feet.

Continuation from page 3
Energy-efficient motors will pay off for you too!
The new IE2 motors achieve the better level of efficiency that
is required due to the improved quality of their metal, more
active material and the increased coil space factor, amongst
others. These adjustments result in genuine additional costs
that are reflected in slightly higher purchase costs.
However, when you take into consideration that 90 % of
the total costs of a motor relate to the operating costs and a
large percentage of this to energy costs, it becomes obvious
that an energy-efficient IE2 motor will be amortised within a
few years (The exact duration depends on the annual operating rate of the motor).

Economical motors are only part of Elektror‘s total concept for energy-efficient blowers and side channel blowers
E
nergy efficiency is a topic that is associated
with mechanical and plant engineering at
present especially due to the new IEC 6003430-2008 standard. And this is certainly not without good reason. If you consider that a large percentage of
the electric motors used worldwide are affected by this statutory guideline, it is obvious that an enormous energy-saving
potential has been identified in global terms. After all, energy
savings of 2-5 % per motor will be achieved through these
measures.
However, our years of experience as a manufacturer of industrial blowers and as a systems supplier indicate that there
is potential to make even greater savings.
S
Selection
of the correct Elektror device
In add
addition to any other device adjustments, it is vitally important that the basic model that is selected can fulfil the requirements. Any over and under sizing must be excluded at
this point so that the energy balance is not influenced in a
negative way.
Experience has made us good
The comprehensive and qualified advice that we provide is
the basis of our total concept for energy-efficient blowers and
side channel blowers. Optimum efficiency can only ever be
achieved when a blower, system and existing basic conditions
are in tune with each other. As a result, we are on hand during and after the delivery of your Elektror device to offer you
help and advice.

Modifi

Whether its accessories, standard adjustments or even deWhet

selected until it is optimally adapted to your individual requirements. In so doing, we give all blower components (impeller,
housing, motor) a vital check with regard to your application.

on many systems, which results in high losses because of
the constant blower speed. Blowers that can be adjusted via
frequency converters provide significant advantages here be-
cause the infinitely variable speed controller ensures that only
the pressure and flow rate that is required for the process is
produced.
Furthermore, process-oriented, sensor-driven controls can
be achieved using frequency converters. The speed of the
blower is automatically regulated to the required operating
point with this version. This is particularly useful in applications where there are changing conditions on the system in
terms of ventilation.
Frequency converter technology is also used these days as
an energy-efficient alternative to a belt drive in order to achieve high speeds and, consequently, higher pressures and flow
rates. Friction losses of 2-3 % can also be saved on top of the
overall lower operating and maintenance costs as a result of a
drive belt wearing part not being used.

Don‘t miss „the connection“
Our new standardised device connectors and connecting elements make
the mechanical connection of Elektror devices a breeze
“D
o you have a device connector within your range that is suitable for
the connection to standardised connecting elements?“
Enquiries that we received from our customers in the past sounded like this or were very similar to this and up until a few months
ago we regrettably had to say „no.“ However, true to our maxim, „Ventilation
technology from Elektror - a one-stop service,“ it is always our objective to fulfil
your requirements - that‘s why we have now expanded our acce

you.

The new high-speed Elektror blowers provide tremendous performance potential with extremely compact device dimensions
S
ignificantly higher pressures with the same device dimensions, a greater level of efficiency and
constant pressure behaviour even with
higher flow rates and energy efficiency
thanks to the use of a perfectly proportioned motor.
These were a few of the requests in
the requirements specification for a new
range of Elektror devices. The objective
was to be able to identify even more applications for blowers in the future. Our
developers were faced with the major
challenge of needing to replace two or
more blowers with one, as well as also
planning to expand into capacity ranges
that could only be achieved by complex
high-maintenance devices (such as turbines) up until now.
responding to a speed of over 7,000
rpm. A pressure of up to 20,000 Pa (at
up to 1,800m³/hr) is produced by this
tremendously high speed – and this is
achieved with the same compact device
dimensions as the standard HRD7 device that has only been able to achieve
pressure ranges of up to 16,000 Pa until
now. This new high-performance blower
is driven by a 15 kW motor that makes it
significantly more energy-efficient than
comparable alternatives.
The first of the next generation has
already arrived
Just a little later we will now present you
with the second device in our BOOSTED
range - the HRD60 FU 135/11.
This small brother of the HRD7-BOOSTED can be operated at up to 135 Hz
and, consequently, moves at speeds of
in excess of 8,000 rpm. With a maximum pressure of 17,000 Pa at 1.800
m³/hr it is ideally suited for applications
for which the previous HRD60 devices
were too weak and the performance
and dimensions of an HRD7 (-BOOSTED)
would have been too large.

The devices presented here stand out
thanks to their consistent pressure behaviour that is reflected in an extremely flat characteristic curve. On the one

In summer 2010 the first device of a
new generation of extremely high-performance Elektror blowers was ready to
go into production.

of ongoing research and development
work and was specifically designed to
be able to work with very high speeds.

siderable number of new applications
for Elektror blowers and, on the other
hand, so many more applications can be
met significantly more efficiently than up
until now had only been possible with
compromise solutions. All devices in the
BOOSTED range are based on standard
devices of the same name and, therefore, have the same dimensions as them
but a significantly higher air capacity.
The systems are largely wear-free
and maintenance-free despite their extremely high power density and they also
provide excellent operational reliability.
To be continued …
Of course, that‘s not all! We are constantly working on the development of
other devices within the BOOSTED range - always with the objective of providing the optimum capacity within a
confined space.
Consequently, even the most diverse
demands in terms of ventilation capacity
can be met with this extremely high-performance and highly efficient solution in
the near future.
A problem recognised is a problem solved
The mechanical connection of your Elektror device with

High-performance blowers
sometimes need a silencer!
An important aspect of worker protection is the prevention of excessive noise levels. Substantial exposure to loud noises can result in negative physiological and psychological consequences for employees in production halls and at large machines. That‘s why we offer the right solutions for you.
Our “muzzle“ for the intake side
Getting really quiet
Elektror‘s disk silencers make less sound
Elektror sound enclosures reduce the noise level of blowers by up to 20 dBA
A
large number of blowers are operated with a direct intake i.e.
without pipework connected to the intake side. With this type of
connection a comparable high volume of noise is generated on the
intake as the natural sound absorption of the pipework is not given.
This means that any noise from the air flow or turbulence can escape from the inside to the outside unhindered.
Disk silencers reduce the noise of air by up to 10 dBA
The disk silencers specifically adapted to Elektror blowers provide significant noise
insulation without compromising the ventilation values.
The compact construction and the easy installation directly onto the housing
cover enable them also to be used in restricted areas. Durable aluminium and fixing
parts made of corrosion-resistant steel, as well as non-flammable sound insulation
material guarantee an extremely long service life.
The Elektror disk silencers are also available with electro conductive insulation
material as an ATEX version.

T
he Elektror product range
includes a large number
of high-performance blowers. Motor capacities of
up to 30 kW and impeller diameters of
up to 710 mm ensure that challenging
applications do not present any problems for our devices either. Furthermore, increases in speed of up to 2.4 times
the normal speed are currently achieved
using frequency converters.
Despite their low-noise design, blowers with these performance levels do
not operate silently. Both the motor and
air noise levels increase when the blower capacity is raised.
Place an enclosure over the noise
Solutions to reduce the sound pressure
level were often complex up until now
and, consequently, very expensive as the
sound insulation had to be tailor-made
for the respective blower. In addition to
the high costs, this also resulted in unsatisfactory lead times in a lot of cases,
not least because we purchased sound
enclosures from an external company
up until now.
Since the middle of 2010 we have been
producing standardised sound enclosures for a total of 25 of our blower types
at present in our new production premises in which we also produce highvolume steel industrial fans. For this reason, the high quality and robust sound
enclosures made in-house in galvanised
sheet steel are significantly cheaper
than the bought-in parts and, more importantly, can be brought to the market
within a very competitive lead time of
four weeks.
Elektror sound enclosures stand out
because of their high quality and functionality. Therefore, the enclosure and
blower are guaranteed to be easy to
maintain despite excellent sound insulation values of up to -20 dBA. Quickrelease fasteners on the side walls, base
plate and roof ensure that the blower
can be easily released on all sides with
only a few simply manual adjustments.
The connections to integrate it into your
system (pressure and intake side flange
connectors included) are outside the enclosure and a recess on the back is provi-
ded to make it easy to insert the cables.
The enclosure is also prepared for transportation by crane or by a forklift.
The encased blower that is installed
onto the sound enclosure in such a way
to avoid any vibration is cooled by means of natural convection i.e. no additional energy supply is required.

he speed of our blowers and side channel blowers can simply be adjusted using frequency
converters and thereby can be perfectly adapted to your application.
Energy costs can be reduced to a minimum with a simple
speed control or a sensor-driven pressure / volume flow control. Consequently, energy-guzzling manual air and pressure
controls become redundant.
But that is not all. Our frequency converters will also win
you over with their integral accessory, protection and monitoring functions. On the one hand, this enables the simple automation of your ventilation system and, on the other hand, this
can help with the early detection and diagnosis of faults on
your system and, for example, prevent any unplanned downtime.

ELEKTROR
KNOW-HOW
Stainless steel blowers - not just clean, but pristine
Aggressive cleaning agents or conveyed media cannot harm the new Elektror stainless steel blowers
E
lektror blowers are used in a whole variety of
industry sectors. Generally air is almost always
the main element of the conveyed media but
there are also a large number of applications
where the blower comes into contact with aggressive substances, such as acids. The same process applies here for both
the conveying of aggressive media and the intensive cleaning
of the blower with acidic cleaning agents. The blower parts
that come into contact with the media need to be particularly
durable in these specific cases in order to achieve a long service life.
Stainless steel is the ideal material in this instance. It is resistant to water, steam, humidity, food acids, as well as weak
organic and inorganic acids, also provides very good anti-corrosive protection at a high level of humidity and, in addition,
has antibacterial properties.
Elektror medium pressure blowers also coming soon in
stainless steel as standard
Within the past few months we were able to detect a noticeable increase in the demand for blowers with a stainless steel design. Furthermore, an extensive analysis of the industry showed
that extremely high standards now apply for plant engineering
in many sectors of the industry that can only be achieved using
stainless steel models.
Therefore, we have decided not just to produce stainless
steel blowers solely for specific projects in the future.
As of the middle of this year, the new range of stainless steel
fans that are based on our RD range (medium pressure blowers) will enhance Elektror‘s product range. We will cover a
large percentage of the ventilation required in work areas in the
relevant sectors with this initial range that has a highly durable
and rust-proof design - customised solutions are of course also
available. A preview of these new devices will be presented to
you as early as April at the HMI fair in Hannover.

Stainless steel blowers - the facts
The new stainless steel range provides the following features:
• Housing, impeller, motor shaft, fixing material and all other
parts that come into contact with the media are made of
stainless steel (material number 1.4301)
• Solid, welded housing
• All devices fitted with a radial shaft sealing ring
• Spacer bolts ensure that the housing cover on the intake
side can be easily removed to ensure that it can be
thoroughly cleaned
• Splash protection - when closed, no fluids escape from the
inside to the outside or vice versa
• Also available for use with frequency converters
• Special customised solutions are possible
Areas of application
Our stainless steel fans are designed for the following,
amongst others:
• Industrial wash plants
• Pharmaceutical industry
• Food industry
• Process engineering
• Many other areas in which specific media are used or
where there are high standards in terms of cleanliness

Then please feel free to contact us!
For several projects we have already completed applications in stainless steel for a few of our customers.
Tell us about your requirements and we will work out a suitable solution - in (stainless) steel too, of course.
We are taking a close look!

a few words.
Day after day the different Elektror
devices are tested to their limit on both
the discharge and intake sides.
The power supply of 120 to 720 V,
max. 85 A at 50 or 60 Hz allows us to
operate the whole Elektror product range in the ventilation laboratory. We are
also able to operate the devices at well
above 100 Hz using frequency converters and, in doing so, test the operating
behaviour at extremely high speeds.
As well as in-process measuring to regularly check our standard devices, we
also primarily test new developments
and customised designs with specific requirements here.

We investigate the following:
• Air flows of up to 140 m³/min
• Random pressures
• Sound pressure levels
• Capacity
• Motor speed
• Motor power consumption
• Motor efficiency level
Fatigue tests can also be done in this test
room without any problems. This means
that extremely powerful or customerspecific Elektror devices can undergo
an operating point load measurement
recording the temperature and the noise. We can also simulate and measure
changing air flow loads, as well as different thermal conditions.

Aggressive chemicals as components
in the conveyed atmosphere?
Our ATEX blowers can deal with this.
An electro conductive chemical protective coating applied to the housing and impeller, as well as a motor
shaft end made of durable stainless
steel make this possible.
Tailor-made solutions for explosion prevention
Our ATEX blowers can also be customised to your individual requirements
F
or a long time now, our customers have appreciated our proven reliability combined with
our technical innovation in applications where there are no risks of explosion. Customised
models that are adapted exactly to the specific application
shape our daily working lives and challenge us from day-today. And succeeding in these challenges is our true strength
because we have accumulated our expertise and knowledge
over many years in this way and you benefit from this as a
customer.
Customer-specific models have now become a matter of
course for us in terms of our explosion prevention designs
too. With the help of a large number of processing and design procedures, we are preparing our three ATEX ranges,
ND-ATEX, RD-ATEX and HRD-FU-ATEX, for a wide range of
applications within explosive areas.
M
Meticulous
and detailed documentation
As a rresult of the strict safety requirements on these devices,
a specific proof of safety must already be prepared at the development phase that must be separately filed away for each
type of device.
The ongoing production process is also subject to a particularly strict process control. Finally, every ATEX blower is
subject to a precise and thorough final check that involves a
significant amount of documentation.

using explosion-proof blowers. To put it simply, any sparks
that the blower produces that could react with an explosive
or ignitable atmosphere are eliminated by making structural
adaptations. In order to make the blowers explosion-resistant
and depending on the customer‘s requirements, they are produced with material combinations that do not generate any
sparks and fitted with explosion-proof motors, etc.

Customer-specifi
c ATEX devices
We ca
can already cover a variety of applications by making minor adjustments to our standard ATEX blowers. However, we
also have the right solution in most cases for particularly ambitious and tough jobs:
Abrasive associated materials in the
conveyed atmosphere?
We also have a solution for this. The
housing and optionally the impeller are coated with DURNI-COAT®,
a chemically isolated layer of nickel
that provides the required surface
properties without compromising
the advantages of the aluminium
cast material on the housings
But that is not all. To separate
the atmospheres subject to different
ATEX zones, we seal ATEX blowers
using the new sealing methods that
have already established themselves outside of explosive areas many
times over. We attach great importance here to electrical potential
equalisation.
This sealing system is also suitable for holding back any aggressive
associated materials, oils or aqueous
solutions that are carried along by
the feed air. The special thing about
this is the traceable residual leakage
rate that is requested elsewhere in
vain.
The procedures referred to only
illustrate a fraction of the options
that we can offer. Elektror‘s Customer Support team is always ready to
listen to any specific requirements
that you may have in terms of your
ATEX blower and will work together
with you to come up with a solution
specifically designed for your application.

Therefore, these plants and any integral components must comply with the standards in terms
of explosion prevention.
A manufacturer of organic source
materials for biogas plants
ATEX blowers as air supply
Our ATEX blowers are primarily used for so-called double membrane gas storage. This
type of biogas plant consists of a shaped outer membrane and an inner membrane that
forms the actual gas-filled compartment. A layer of air with a constant pressure sits
between both membranes. It ensures that the outer membrane keeps its shape and, at
the same time, that this pressure is applied to the inner membrane in order to feed gas
into the supply network.
A constantly running ATEX blower outside the membranes feeds air into the gap
in between and keeps the pressure constant. An electronic speed control adjusts any
fluctuations in the amount of gas in the inner membrane within a few moments so that
the outer membrane always keeps its shape.
Although the blower in this case is outside the area filled with biogas and conveys
normal air (no biogas), it must still comply with the ATEX requirements. The reasons for
this are any possible leakages from the plant or any blowbacks of gas in the direction of
the blower. Should such an emergency occur, there must be a guarantee that escaping
gas is unable to ignite on the blower.
ATEX blowers for intermittent conveying of explosive gases
In a few cases the biogas is conveyed directly through the blower. For example, this may
be the case when any overpressure in the gas-filled compartment has to be adjusted or
any gas collected has to be transported into larger storage tanks.
The aggressive substances contained in the biogas and the changing concentration
and composition make this application very challenging and call for a few adjustments
to the ATEX blower. In addition to the special seal with its particularly lower leakage
rate, the following features ensure that it has a comparable service life to conventional
ATEX devices.
• An electro conductive chemical protective coating of the impeller and housing
• Extremely resistant shaft material
• A special shaft seal with ATEX approval that protects the drive side ball
bearings on the (variable frequency) motor from the aggressive components in the
biogas (acids and alkaline solutions)
We fulfil the highest technical demands - in ATEX areas as well

Powerful and adaptable bolides made of steel
We have already been able to fulfil many ambitious customer projects with our steel centrifugal fans
F
or more than three years now we have been
producing high-volume steel fans in-house as
an addition to the existing aluminium cast blowers within our product range. The different
conveying and processing properties of both basic materials,
steel and aluminium cast, as well as the different power ranges enable us to fulfil a large number of different applications
these days.
The centrifugal fans in steel housings are always used when
• very large amounts of air need to be conveyed,
• the shape of the housing and components must be
extremely well adapted to the application and
• the steel material offers distinct advantages over aluminum
cast with regard to the specific application (weight, surface, etc.)

hy do we not ask our customers themselves
what we could do better for them?“ This was
what our Managing Director, Ulrich W. Kreher,
came up with one day. This was when the idea
of carrying out a customer satisfaction analysis was introduced. We set about this ambitious project immediately with the
objective of continually further developing and improving our
quality and service for you as a customer.
We were able to successfully conclude the first professionally run Elektror customer survey on 14 July 2010 after a 6
week period of questioning. A total of 484 customers were
interviewed over the telephone by DIMA, an independent
market research institute. 380 of these were in Germany, 54
in Austria and 50 in Switzerland. The respondents were selected randomly from our active customers.

A final word regarding data protection
We were and are exclusively interested in your personal opinion
regarding our company.
As an independent market research institute, DiMA Marktforschung GmbH is strictly bound by the Federal Data Protection Act. Therefore, it goes without saying that the results were
not evaluated in terms of individuals or companies.
Your personal anonymity and voluntary participation in answering the questions formed the basis of this study. Your answers were handled with the utmost confidentiality and your

S
ome people may be surprised at this statement, but even a „blower“ that initially sounds
very simple, can require extensive advice. The
selection of the right device, countless adaptations, various accessories, as well as the very precise design,
often with the aid of electronic components (e.g. frequency
converters), require excellent applied knowledge and lots of
experience.
We opened the Customer Support department at Elektror
many years ago to make it as easy as possible for you. Since
then we have established a very experienced four-man team
that has already been able to provide assistance to many customers within a short period of time.

then, please contact Robin Banerji or Marloes Broshuis with
any questions that you may have.
We still have lots of plans...
In creating this European distributorship, the third already,
Elektror is systematically pursuing its expansion strategy. We
also want to achieve considerably closer proximity to customers, an appreciable increase in brand awareness, consistent
growth and more comprehensive market presence over the
coming months and years as a result of launching more subsidiaries.
F
or nearly 100 years, since 1912 to be precise,
Ritter Sport has been making and selling chocolate. Famous for its square shape that fits
into nearly every jacket pocket, it‘s unimaginable not to have the many flavours available on the shelves of
supermarkets and retail stores these days.
Ritter Sport does not make any compromises in terms of
the quality of its products. The highest value is placed on perfection in terms of flavour and „looks“ from the start as a
raw material through the production process to the finished
product.
Numerous production steps are required
when manufacturing chocolate
Initially, the different ingredients must be mixed together with
the cocoa paste. Then comes the refining of the chocolate
paste - the finer the paste becomes, the less “sandy“ the taste
on your tongue when eating the chocolate at a later date. And
subsequently the paste is then conched. This involves heating
it to 90 °C and stirring it until the paste is fine and smooth.
As the chocolate is still too hot and runny for further processing when it leaves the conching process, it is now slowly
cooled along a specific temperature curve to approx. 28 °C
- this is called tempering or also precrystallisation. This production step is vital for the silky matt gloss and the breakage
(the “crunchy“ noise when you break the bar).
Elektror medium and high pressure blowers are used in
the chocolate tempering machines at Ritter Sport. They are
responsible for the evenly distributed and precise cooling. The
non-contact cooling using a flow of air is ideally suited for
tempering the chocolate paste gently and without the risk of
any contaminants. It is vitally important here to meter the air
precisely to achieve a steady tempering rate as cooling too
fast would lead to the formation of a fat bloom on the surface of the bar of chocolate. This is in fact harmless in terms
of flavour but not very appetising to look at - an effect that
everyone is aware of if they have ever placed chocolate into
their fridge.
Finally the perfectly tempered chocolate is poured into chocolate bar moulds where it cools down further. Our blowers
also support the evenly distributed cooling of the chocolate
during this process. At the same time, any excess chocolate is
blown off using a perfectly metered air curtain that ensures
that the surface of the chocolate is lovely and smooth.
Our extremely close and excellent partnership with the
manufacturer of the chocolate tempering machines for Ritter
Sport ensures that we can design our blowers ideally for this
application using detailed measurements. In conjunction with
high precision and individually produced Elektror Airknives,
a uniform discharge of air is also guaranteed for the whole
width of the material line. The varying requirements in terms
of air capacity can be implemented without any problems
using frequency converters.
This way, Elektror blowers, amongst others, also provide
for the full enjoyment of the tasty, square and practical Ritter
Sport chocolate bars.

Our connection to the local heating network
“Cool“ climate in Elektror‘s headquarters
Local heat and geothermal energy provide environmentally friendly and efficient air conditioning for our
headquarters in Ostfildern
T
he total floor area of the Elektror headquarters in Ostfildern is approximately 6.000 m².
Our architects and in-house engineers came
up with a sophisticated and, at the same time,
environmentally friendly air conditioning system in order to
heat or cool this enormous area to pleasant room temperatures at all times of the year.
Use of “waste heat from waste“
The main role of the nearby wood chip plant is to produce electricity for the “Scharnhauser Park“ area of Ostfildern
(Elektror‘s headquarters is also located here). This is achieved
by burning biomass, a large percentage of which is covered
by wood chip.
Any heat loss resulting from this is not released unused
back into the environment but instead made available for use
as local heat by any private or commercial buildings. Elektror
is also connected to this local heating network.
What is special here is that the waste heat that is available
all year round can be used to both heat and cool the Elektror building using two heat exchangers. In summer the waste
heat is simply used to chill. No boiler operates in the building
itself but an additional cold compression system that produces
electricity is only used in winter to cool specific rooms (e.g.
server room). This means that only the minimum amount of

heat
104 so-called energy stakes made of concrete were inserted
6-9 metres into the ground under the Elektror building. These
concrete stakes are activated as heat exchangers and supply
+3 °C to +5 °C natural heat from the ground. In winter they

are used to preheat the fresh air that is used to ventilate the
building or in summer they are used to precool it. Consequently, the energy required to generate ventilation air to maintain
a room temperature of 20 °C is once again reduced.
The extract air from the building is discharged again to a
central point on the roof using heat/cold recovery.
Concrete core activation and the right
control engineering
The Elektror building is heated and cooled using so-called
concrete core activation. Concrete is an ideal material for consistently storing and releasing heat and cold. To this end, several hundred meters of ducting were laid in all concrete ceilings
above the ground floor by the building contractor. The waste
heat from the wood chip plant moves through this ducting,
after passing through the heat exchangers, directly into the
room ceilings that then take on the basic temperature control
for the room air as cooling or heating surfaces.
A special building management system brings together all
components from this complex air conditioning and ensures
it is both environmentally friendly and efficient in its operation. For example, the control of the concrete core activation is
optimised using the weather forecast from a meteorological
service and also the whole lighting and blind shading on the
building is fitted for flexible and cost-effective operation. Furthermore, all building services can be centrally managed by
Elektror‘s Facility Management.

RAL 7035 is a new standard colour for all Elektror
devices since 1.1.2011
F
ollowing many suggestions from our customers we
changed the standard coating on Elektror devices
on 1 January 2011. Our former, ageing standard colour,
RAL 7032 (pebble grey), has been replaced with the more
modern and pleasant RAL 7035 (light grey) colour. By making this change, the standard coating on our blowers and
side channel blowers has now been altered to the colour
that has since become the common colour within tool and
plant manufacturing.
Of course, your Elektror devices are still also available
without any coating or in any other colour - just get in
touch with us.
