Substations – hubs in our
electricity grid
Dear readers,
the energy revolution in our country is
an enormous challenge for all concerned.
Two of the central questions are how to
transport most of the wind energy which
is developed in the North to the South
of Germany and how to bring the energy
which is generated offshore onto the land.
You can read about the role which our
ENERGY division is playing in this billion
Euro business in our title story.
I was delighted with our award
in the competition for "Hamburg's
best employer 2015" in the category
"Compatibility of work and private life".
This award confirms what we have
practised at HEROSE for many years:
finding individual solutions which
optimally combine private life and work
together with our employees.
I wish you a pleasant start to spring!
Dirk M. Zschalich
Managing Director
HEROSE has supplied, tried and tested valves for oil-cooled transformers for many years. Product Manager Thorsten Zeug: “An attractive
market, especially for the future”
In principle, our electricity grid can be
compared with a road network. There are
motorways for long distances, main roads
for medium distances and simple local
roads which lead to our houses. These
are interconnected with crossroads
and junctions. The motorways are the
very high voltage lines with a voltage of
220,000 or 380,000 volts (corresponding
to 220 or 380 kilovolts). The higher the
voltage the lower the energy losses during
the transportation of the electricity. To
transport the energy over very long
distances as efficiently as possible, the
electricity is transformed to the highest
possible voltage at the places where it is
generated, namely at the power stations.
This is done with transformers. Most of
these transformers are cooled with oil,
in some cases with quantities of up to
40 tons. HEROSE valves for oil-cooled
transformers have proven themselves
for decades in heavy-duty use for
electricity generation and distribution. At
present, these include gate valves with
dimensions from DN 25 to DN 250 (see
also page 3).
After this, the energy is transported
via very high voltage overhead power
lines over hundreds of kilometres to the
consumption centres. Because of this, the
220 and 380 kilovolt lines are often also
referred to as the "transportation grid".
Substation Wahle
Title Story
In transformers like these, up to 40 tons of oil are needed for cooling
The high voltage grid with a voltage of
110 kilovolt is connected to the very high
voltage grid. Similar to main roads, this is
used for the rough distribution of energy
within the region. After this, medium and
low voltage lines with a voltage of 10, 20
or 30 kilovolt bring the energy directly
into our towns, usually via underground
cables. After a further transformation,
the electricity in our plug sockets only
has a voltage of 230 or 400 Volt.
What is the role of the substations?
Here, the power lines with various
voltage levels meet and interconnect –
just like at a crossroads. Via the very high
voltage lines with 220 or 380 kilovolt, the
electricity is transported from the power
stations to the substations, which it is
transformed down to the lower level of
110 kilovolt.
The same process is carried out at
the next stages. The different voltage
levels are coupled together with large
transformers. From the substations,
the electricity is then supplied to the
consumers. The substations collect
the electricity from the power stations,
convert it to a lower voltage level and
distribute it further.
This process is increasingly being used
in the reverse direction. Over the past
decade, in addition to the large central
power stations, an increasing number of
decentralised, regenerative generation
plants have been installed. These
2
include domestic solar energy systems
on roofs as well as large wind parks on
the coast and out at sea. The local and
regional grids collect the regeneratively
generated energy and transport it to the
nearest substations.
The offshore substations constructed
far out at sea are especially interesting
for HEROSE. Thorsten Zeug, Product
Manager ENERGY at HEROSE since
June 2013: "Especially here, far out from
the coast, components need to be of
the very highest quality. A leaking gate
valve would be dangerous, not simply
from an environmental point of view. To
make a repair, 40 tons of oil would need
to be drained off, which would involve
a downtime lasting several weeks with
unforeseeable financial consequences."
Zeug believes that HEROSE is well
prepared: "Our valves for offshore use
are ideally suitable due to special alloys
and coatings. This has been confirmed
with corrosion tests in salt water." Zeug
has an ambitious aim: "We intend to
considerably increase the share of the
ENERGY division in the total results
during the coming years." For this, the
graduate process technician often has
to travel. In this time, he is in Dubai at
the MEE exhibition from 2 to 4 March.
Thorsten Zeug believes that the greatest
competitive advantage of HEROSE is
"the fact that we have a great deal of
experience in constructing valves for
transformers – and that we can cater for
customers' individual requirements."
HEROSE valves are also suitable for offshore
substations
Grid operator TENNET
Tennet is Germany's main operator
of high voltage electricity grids. The
German subsidiary of a Dutch company
has 1,000 employees and is responsible
for a 21,000 kilometre high voltage
grid, which covers 40 % of Germany.
Tennet also plays a leading role in the
planning of major power routes which
will transport regeneratively produced
electricity from the North to the South
of Germany.

"This is what we practice"
HEROSE Managing Director Zschalich on the award for "Compatibility of private and professional life"

Schröder receiving the prize in Hamburg
High praise for HEROSE: In the
competition "Hamburg's best employer
2015" the HEROSE received an award
in the category "Compatibility of private
and professional life". Randomly selected
employees were given a questionnaire
which they filled in anonymously. Their
good assessment resulted in the award
which was presented to HEROSE
Managing Director Dirk Zschalich in
Hamburg on 4 February.
In the responses by the employees
there was widespread agreement with
the argument that flexible handling of
the subject of compatibility of work and
private life has always been practised
by HEROSE. No matter whether an
employee's child suddenly becomes ill or
if a longer break from work is necessary.
"We don't have any glossy brochures on
the subject. We practice this philosophy
in the form of individual solutions. That
was always the case," says Managing
Director Zschalich. Human Resources
Manager
Markus
Schröder
adds:
"Obviously, the work in hand must be
done, but we are very flexible with regard
to the time structure."
Michael Bentz, 50, who works in the
technical customer support and has
been with HEROSE for nearly 10 years,
was able to reduce his working hours to
4
35 hours per week after he became a
widower and suddenly had to look after
his two children. "The company showed
great understanding about this." Anne
Schiemann, who has worked in the
assembly of safety valves for HEROSE
for twelve years had other reasons for
reducing her weekly working hours:
"Nine years ago I was diagnosed as
having multiple sclerosis. After two
severe attacks in 2010 I now become
tired very quickly. Because of this, my
doctors recommended a reduction in
my working hours. Since then, Anne
Schiemann only works half days. "I am
very thankful for this concession, as
after all, I had a full-time job." The third
example is Nikolaj Ehmke, 29. He has
been with HEROSE since 2006, works
in the Development department and
has completed a dual course of study in
Mechanical Engineering. A few months
ago, Ehmke started an in-service
course of study at the Nordakademie
in Hamburg, with the aim of achieving
a Master of Management and Business
Administration qualification. "This year
alone, I have been given six weeks paid
leave by the company." At present,
HEROSE is enabling three employees
to carry out an in-service course of
study.

Competition
The competition for suitable employees is increasing
noticeably. In this competitive situation it is
becoming increasingly important for companies to
present themselves as attractive employers. Against
this background, Prof. Werner Sarges from the
Helmut-Schmidt Univiersity in Hamburg, the IMWF
Institute for Management and Business Research,
alster radio 106.8 and the Hamburger Abendblatt
newspaper initiated the annual "Hamburg's best
employer" competition in 2009.

Public relations is an important aspect of the work of the Marketing
department and setting the strategic direction of the company

Marketing includes all of
a company’s activities in market
analysis,
advertising,
and
targeted product development
with the objective of increasing
sales. At HEROSE, Mario
Esche is responsible for this
important field. The 33-year-old
industrial engineering graduate
has worked for HEROSE since
2012. He is assisted by Oke
Rusch, who was trained in the
profession of industrial manager
here at HEROSE.
Esche divides his tasks into
two main categories: operative
and strategic marketing. "On
the basis of analyses of the
market and our competitors, we
assist the strategic direction of
the company, in the decision of
which products to concentrate
on and the setting of targets",
says Esche. Investigations by
the department have played
a major role in the "HEROSE
2022"
programme.
Esche:
"For example, all of our figures
confirm that it is entirely right to
intensively promote the field of
LNG."
In contrast to strategic
marketing, there is operative
marketing. Public relations
forms an essential part of this.
"For example, the magazine
which you are now reading is
a typical operative marketing
instrument", says Esche. Just
like the HEROSE internet
presentation, it is used to inform
business partners and potential
customers of all that they need
to know about products and
new developments.
The Marketing department
is also responsible for placing
advertisements
in
trade
magazines. The important topic
of "exhibitions" is also part of
the agenda. Esche: "HEROSE
The HEROSE Marketing Team Mario Esche (right) and
Oke Rusch
participates in between five and seven
exhibitions each year throughout the world, as
well as many conferences. We coordinate the
activities with our advertising agency and are
also responsible for the design of our exhibition
stands, for the catering and sending out the
invitations." The Valves Community Workshops,
which are concerned with the subject of
"cryogenics" and which are held four times per
year in Bad Oldesloe are also the responsibility
of the Marketing department.
The challenges for the future? "We are noticing
that our customers are becoming increasingly
digitally orientated", says Esche. A possible
consequence of the increasing access figures in
the field of mobile devices such as smartphones
and tablets is our own HEROSE app. "We are
working on this."

Cleaned and degreased for oxygen service –
Top values regularly confirmed
Dräger in Lübeck analyses control plates from Bad Oldesloe four times per year

Pannwitz
nods
in
confirmation. The infra-red spectrometer
shows the chemical engineer at Dräger
in Lübeck what he has already known
from HEROSE for many years: The oil
content of the submitted control plates
is far below the specified values. The
device only shows 0.03 milligrams per
square centimetre. Five milligrams, i.e.
more than 150 times this value would
still comply with the statutory standard.
When globe and other valves are used
in industrial plant, it is usual to reduce
Karl-Heinz Pannwitz with a sample plate from HEROSE
friction by lubricating the moving thread
(spindle thread) with oil and grease. In
most cases this does not cause any
problems. However it can cause serious
accidents in the case of valves which
are used for oxygen service.
Why is this? In an atmosphere
which is enriched with oxygen, oil and
grease can ignite spontaneously – and
explosively. In oxygen equipment,
grease and oil often cause a chain
reaction which can ultimately result
in metals igniting or melting. In such
cases, the remains of the melted or
burnt metal are ejected from the valve
body and oxygen can then escape. This
causes an intense and rapid spread of
the fire to flammable materials outside
of the equipment.
HEROSE valves cater for this by
the use of especially suitable pairs
of materials, constructional design,
careful deburring of each individual
component – in some cases by hand
– and high precision assembly under
almost clean room conditions. All of
Welcome to the ACHEMA 2015
HEROSE will be exhibiting on Stand G23 in Hall 8
From 15 to 19 June, the Frankfurt
exhibition grounds will once again host
the ACHEMA – the world's leading
exhibition for chemical technology and
the processing industry. As in previous
years, HEROSE will have its own stand
at the exhibition – in Hall 8, where pumps,
compressors and valves are exhibited.
Managing Director Dirk Zschalich: "The
ACHEMA is a meeting point for the
global valves industry, which of course
we cannot miss." The 80 square metre
6
stand in the new design is divided into
the areas CRYOGENIC and INDUSTRY.
In addition to the familiar range of
products, we will also be presenting
innovations and additions to the
product ranges. You can look forward
to seeing new products from the series
of safety and globe valves.

the materials which are used are tested
with regard to their suitability for use in
combination with oxygen by the German
materials testing facility 'Bundesanstalt
für Materialprüfung (BAM)' using test
procedures according to DIN EN 197
To ensure freedom from oil and grease,
regardless of its future use, each valve
passes through a specially developed
cleaning process.
The results of cleaning are regularly
monitored by Dräger in Lübeck, who
has a license for this. "HEROSE has
now been our regular guest for 14
years", says Chemical Engineer KarlHeinz Pannwitz. Every three months
the Bad Oldesloe company sends six
control plates with the dimensions
10 x 10 centimetres to Lübeck to have
the effectiveness of the degreasing
machine tested. Pannwitz on the testing
method: "The plates are first washed
in perchlorethylene and then the liquid
which is obtained is analysed in an
infra-red spectrometer." The results
are documented, so that HEROSE can
prove the almost complete freedom
from oil and grease in its valves at any
time.
The requirements for freedom from oil
and grease are subject to the European
standard EN 12300 "Cleanliness for
cryogenic service". The limiting value of
500 mg/m2 which this standard specifies
must be considerably undershot, as in
some customer specifications only 100
mg/m2 are permissible. With a special
cleaning process, HEROSE achieves a
purity value which is far lower than this.
Therefore, all HEROSE cryogenic
valves up to DN150 are suitable for use
with oxygen – and special indication
of freedom from oil and grease is not
necessary in the order.
