When everything fits
To us, perfection in our product portfolio means that all product
series in the area of encased radial fans are attuned to one another
and are 100% compatible in their dimensions.
How did we do it?
By using an identical design for the connection dimensions of every
fan size in our newly developed series ADH-E and RDH-E and
carefully coordinating our options and accessories.
In this way, we have standardised and harmonised our product
portfolio in all relevant areas.
Well designed, easy to install,
economical
A system that saves space, time, and money – in an air handling
unit or any other application: our compact base frame offers
decisive advantages:
A The frame lengths have been optimised and
adjusted for the casing position and motor
installation height to achieve the smallest possible overall height
and length
A Exact, optimised coordination of all components, all the way
through to installation, adjustment and testing
A Suitable for all fans of the series ADH-E0, RDH-E0 and RZR-11 up
to size 0500

proSELECTA II
Simple and reliable selection
proSELECTA II is a technical selection program that allows you to
configure your own individually designed fan. It provides you with
the opportunity to choose from the entire range of fan types and
their associated options.
The result from proSELECTA II is the provision of all the
technical data for your fan, including sound level data, dimension
specifications and accessories. Apart from that, as a registered
user, your purchase prices are provided. Additionally fully
dimensioned drawings in DXF format are available, which can be
downloaded and transferred straight into your CAD system.
So that you can be sure
Models and options that are technically not permissible, are
automatically excluded in proSELECTA II. So there is no chance
that you will configure a “wrong” device option.
What else is important to you
During the fan selection process, you can choose any of the
standardised ATEX options.
Free registration and many advantages
You can register as a proSELECTA II user with us, which enables us
to offer you faster order processing. What this means for you is:
A The complete configuration of your fan with its associated system
accessories and belt drive layout.
A The possibility to produce fans that operate via a frequency
inverter.
A The option of saving your own fan configuration on our server.
A The opportunity to modify your saved configuration, even over the
phone to your Nicotra Gebhardt representative.

Working towards perfection
The RDH E and RDH series
Like the ADH E range, with the serie RDH E we have taken the next logical step in
further developing our successful RDH range of models.
The aim of our development work is to ensure that the dimensions of all casing for
the RDH E and RDH range are compatible with the relevant sister models from the
forward-curved series (ADH E and ADH). In future, we will also ensure compatibility
with the hollow aerofoil impeller types from the RZR series.
As part of the development work being undertaken across all product ranges, the
quality of the RDH E series has also been improved. For example, it now has standing
seam casing which is manufactured during a fully automatic process, and the impeller
shaft is galvanised.
New choice of models
Whether you are looking for single or twin fans, the new RDH E series offers impressive further improvements in terms of functionality and potential uses, whatever the
application.
The ultimate in compatibility
The RDH E and RDH also entail minimised design effort for you, which means that:
 All accessories and equipment are carefully coordinated (and identical with the
ADH E/ADH).
 The connection dimensions for RDH E (sizes 0180 to 0560) are identical with the
corresponding models from the old range RDH and the ranges ADH/ADH E.
 The models for sizes RDH 0630 to 1000 remain unchanged.
 All RDH E models up to size 0500 are compatible with the new compact base
frame – a unique feature which makes completing your system ultra simple and
affordable!
Top quality for performance and a long service life!
Alongside an intelligent construction, aspects such as the quality of materials and
workmanship play a crucial role in ensuring a long life cycle. That’s why – like the
ADH E – we have made the casing of the new RDH E even sturdier by means of a
standing seam construction. Apart from that, the tried and tested quality of our successful, long-standing RDH series remains the same. And that means robust impeller
constructions, non-corrosive impeller shafts and quality bearings – for a long life with
minimum noise.

Continuously welded blades
Impeller blades can be continuously welded in order to increase the corrosion
resistance when conveying a humid or slightly aggressive medium. The continuous
welding has no influence on the material resistance or on the max. tip speed.
Continuously welded scroll
The casing can be continuously welded in order to increase the corrosion resistance
when conveying a humid or slightly aggressive medium. By continuous welding the
casing is provided with additional impermeability.
A GEH 01 - Casing inside continuously welded
A GEH 02 - Casing inside and outside continuously welded

Split Casing
There may be a lot of reasons to choose a split casing, the advantages of split casings are:
A smaller openings for fan chambers
A easier refitting of fan
A easier transport to site
A easier access to impeller for cleaning and maintenance
The joint face on the casing position runs horizontally above or under the fan axis
(see drawing). The reinforced side frames are not divisible. The fan is supplied fully

Volumeter
pin
With the flow measuring device it is possible to easily measure/monitor the flow rate
after the fan is installed. A pressure tapping at a predetermined position on the inlet
cone is provided whereby the differential pressure in relation to the static pressure is
measured in front ofthe inlet cone in a static atmosphere.
Permissible media temperature: +80 °C (RZR), +70 °C (RDH).

Measuring connector in inlet cone
Hose pipe to connecting piece in the side wall
Connecting piece (external diameter of 6mm) for the pressure
measurement
In order to calculate the flow rate, a calibrating factor "K" is required. This factor is
determined by comparativemeasurement on a standard test rig.
Standard-calibration faktor K
Where fans are built into a plenum, the pressure difference between the static pressure in the inlet side plenum and the pressure on the inlet cone is to bemeasured.
It must be ensured that the static pressureto be measured in front of the inlet cone is
not tampered by dynamic pressure fractions.
It is often recommended to arrange a ring of points on the wall facing the outlet side
as illustrated in the sketch.
When using the K‑factors specified below, a minimum clearance of 0.5×D between
the inlet cone of the fan and the side wall of the plenum must be maintained.
Indentations that obstruct the flow to the cone canlead to faults when measuring the
flow rate.
In the event that the differential pressure is fed via a pressure sensor, the signal can
also be used for regulating purposes.

Relubrications
Series RZR
The lubrication unit IWN allows the fan bearings to be greased even when in operation.
The lubrication tubes screwed into the bearing housing are lead out and fastened at
the side wall of the fan.
If desired, the lubrication tubes can be lead to the drive side of the fan.
A IWN 01 - uses standard grease
A IWN 11 - uses moisture resistant grease
ADH / AT / RDH
RZR
For more details see "Technical Description" - "Bearings"!
Series ADH / RDH
The bearing housings of the fan ranges ADH / RDH E4, E6, E7 or K, K1, K2 and AT
AR, TIC are equipped with directly fitted grease nipples.
Mounting feet
Feet made from galvanized steel, either mounted or loose, enable the fan to be installed with a 0, 90 and 270 orientation.
Protection guards
The fans are designed for installation in equipment and as standard are not equipped
with protective guards.
They should not be put into operation before all protective devices are fitted
and connected!
Protective measures must be carried out as set out in DIN EN ISO 12100 "Safety of
machinery - Basic concepts, general principles for design".
If the application of the fan allows free access to the inlet and discharge apertures,
safety devices must be put in place on the fan in accordance with DIN EN ISO 13857!
Suitable safety guards are available as an optional extra.
Shaft Guards
Contact guard for the free end of the shaft for double inlet centrifugal fans. Models in
accordance with DIN EN ISO 13857, made of painted steel mesh.
Flanges
Made from galvanized or painted steel, to connect ducts and system components to
the fan outlet side.
Flexible Connections
Connecting piece with elastic intermediate section for the vibration or impact-noise
decoupled connection of the fan to the system or unit. Made out of two connecting
flanges with elastic intermediate section.
Temperature range / Application
A Standard up to +80 °C
A ATEX max. +60 °C
52
Anti Vibration Mounts
AV mounts are designed to prevent noise and vibrations being transmitted through
the base of the fan.
AV mounts should be mounted beneath the fan base frame so the weight and
spring deflections are evenly distributed. They should not be mounted symmetrically
because a counter force is induced into the system by the pressure created by the
working fan.
It is difficult for the manufacturer to establish the position of the AV mounts to suit all
types of application.
Vibration and noise insulation can also be improved by ensuring that the fan is connected to its external environment by a flexible coupling.
Fastening for CC-profile
Rubber pads and buffers for both vibration and noise insulation at fan speeds
above 1400 rpm or 850 rpm.
Fastening for U-profile
Rubber buffers for noise insulation only at fan speeds under 800 rpm or 1700 rpm.
Spring diffusers with noise insulation layer and height adjustment, for both vibration
and noise insulation at fan speeds above 400 rpm.
Available AV mounts for different fans, see proSELECTA II.
The AVM-mounts are supplied with the suitable mounting material for the
base frame.

This compact base frame with integrated motor tensioning slider provides optimum
compactness and easiest handling.
A The base frame made of galvanized sheet steel is screwed directly onto the fan
(without any casing feet) – the result being the low overall height of the system.
A The overall length depending on the casing position and size of the motor is a
further factor influencing the optimum compactness.
A The integrated tensioning slider considerably simplifies re-adjustment of the belt
drive during maintenance and service work.
G1Z-component size 0400/-0710
The base frames up to motor size 180 are manufactured from galvanized CC-profiles.
The anti-vibration mounts in the CC-profile provide infinitely variable adjustment.
From motor size 200 the base frames are of U-profile, welded and painted.
Fitted motor tensioning tracks that allow the motor to be shifted longitudinally, allow
for the simple adjustment of the belt tension.
G1Z-component size 0800/-1600
Base frame of stable U-profiles, welded and painted, with holes for attaching the antivibration mounts.
Fitted motor tensioning tracks that allow the motor to be shifted longitudinally, allow
for the simple adjustment of the belt tension.
Equipment
A FKS hot-dip galvanized for U-profile base frame
Pick-A-Back
This allows the motor to be fixed directly onto the fan casing, where space around
the fan is limited. One side of the pick-a-back is fixed to the casing so that it swivels,
while the other is supported on a spindle. Thus the pick-a-back becomes adjustable to leave room for tensioning the drive belt. The various motor arrangements and
casing positions are shown in the drawings.
The accompanying tables also show the maximum permissible motor sizes.
When using a pick-a-back arrangement and fitting anti vibration mounts (AVM) an
additional base frame for fitting the AVM may be required depending on the position
of the centre of gravity of the whole fan set.

Fan Sets
Belt Drive
Wedge Belts
High performance narrow V-belts in accordance with DIN 7753 are temperature stable up to +80 °C, resistant to mineral oils and electrostatically conductive.
The belt pulleys are made of high quality cast iron and, depending on the peripheral
velocity and number of grooves, are statically (G 16) or dynamically (G 6.3) balanced.
They are fastened to the shaft of the motor or fan by means of a clamping bush.
Flat Belts
The flat belt drives employed are made using the most modern technology and materials. They are the centrepiece of highly developed, powerful belt drives.
This modern flat belt drive has distinct advantages over traditionally employed V-belt
drives and exceeds it in efficiency, quiet running and economy.
Overview of the advantages:
A higher efficiency
A longer service life
A quieter running
A easy to install
A low maintenance
A no wear on the belt - so it is possible to dispense with the 2nd filter stage in the air
conditioning unit (in accordance with VDI 6022)
Belt Guard
Totally enclosed belt guards are made from galvanised sheet steel in accordance with
DIN DIN EN ISO 13857.
The front section can be removed for maintenance. If there is no standard belt guard
available for the selected belt drive (see table), a suitable belt guard will be made as a
welded construction and then coated.
Features
A belt guard split horizontally
A access door on belt guard
A opening on belt guard for speed measuring device

Fan Sets
Min. Pulley-Diameter, Bearings Life Expectency
As a principle, the fans are only equipped with noise tested precision bearings designed for a nominal bearing life time (L10h acc. to DIN ISO 281-1) of 40,000 operating
hours.
In order to not exceed the admitted bearing loads there are minimum pulley diameters
defined to be respected when sizing the belt drive.
The minimum pulley diameters indicated are to be applied for belt drives
selected according to the state of the art and tensioned according to the
prescriptions.
For flat belt drives the minimum pulley diameters are to be increased of 40 %
to the indicated figure!
A correct design of a belt drive may be achieved with our selection software where all
relevant parameters will be kept automatically.
For correct design of a belt drive made by external means, dimensioning and the
application of the tensioning forces have to made in full respect of all specification
data indicated.

Belt Tensioning
The correct belt tension is achieved when the measuring marks LMu have increased
by the stretching value e*. This should be carried out in two stages to prevent overstressing of the bearing.

A further simple method for setting or checking the correct belt tension is via the
static frequency of the drive belt.
Here the flat or V-belt is set to oscillate freely through striking it whilst stationary.
These vibrations are measured using an electronic measuring unit (e.g. a belt tension
gauge). The vibration frequency in Hz must then be set to the specified value (documentation / nameplate).

Detailed instruction on tensioning are included within the operating and
maintenance manuals.

Description
General
The high-performance centrifugal fans are the result of extensive and systematic
development work.
These technically first-rate products are distinguished by their high efficiency, the
large pressure differences attainable and low noise levels.
The sizes are geometrically scaled in accordance with the standard range R 20 and
the nominal size stated is the external diameter of the impeller.
Media
The fans are suitable for handling air and other non aggressive gases from -20 °C up
to +80 °C, resp. +100 °C.
The ambient temperature at the drive motor must not exceed +40 °C.
Protective installations
The fans are designed for installation in equipment and as standard are not equipped
with protective guards.
They should not be put into operation before all protective devices are fitted
and connected!
Protective measures must be carried out as set out in DIN EN ISO 12100 "Safety of
machinery - Basic concepts, general principles for design".
If the application of the fan allows free access to the inlet and discharge apertures,
safety devices must be put in place on the fan in accordance with DIN EN ISO 13857!
Suitable safety guards are available as an optional extra.
Shafts
Shafts ADH / AT / RDH
The fan shafts are manufacrured of ground, precisely rounded carbon steel C40.
They are principally prepared without being stepped at both ends.
The shafts of the RDH K1 and K2 ranges, size 1000 are machined on both ends for
fitting a pulley.
ADH / AT from size 12/9 / RDH
The shafts are equipped with a keyway (open shape) at both ends and a key (type 2).
AT 7/7 up to 10/10
The standard construction is the version with flats on shaft ends (type 1), it is also
available the version with keyways (type 2).
For corrosion protection the shafts are galvanised up to fan size 0560 and 30/28.
From size 0630 and larger the shaft are covered, between bearing and hub, with a
paint in order to ensure corrosion protection.
The shaft ends are covered with a wax product easy to remove.
Shafts RZR
The shafts are manufacured of precisely rounded carbon steel C35, pared and polished.
Up to size 1000 they are not stepped at the shaft end.
For sizes 1120 up to 1600 the shafts are machined on both ends for fitting a pulley.
The shafts are equipped with a keyway at both ends and a key executed according to
DIN 6885-1.
A Groove shape N2 (open) Sizes 0200 up to 1000
A Groove shape N1 Sizes 1120 up to 1600
The shafts are covered with a easily removable wax product for corrosion protection.
Housig feet / Side frames ADH / AT / RDH
For easier installation of the fan the mounting feet and reinforcing frames are provided
with eye holes.

Description
Motors
Standard motors of wellknown brands, type of protection IP55, thermal class F, are
used. During commissioning and maintenance the detailed instructions provided by
the motor manufacturer (type plate/motor operating instructions) must be followed,
this also applies to the motor protection devices required onsite. The motors are
equipped with PTC resistors/temperature sensors as standard. Motors with integrated frequency inverters may be supplied on request.
EX-ATEX motors
Fan sets of centrifugal fans according to Ex-ATEX execution are equipped with motors of the correspondent category.
For frequency inverter operation the motors will be of pressure resistant execution.
Speed regulation
A suitable speed variation system is required for the optimum adjustment of the
desired operating point.
Our frequency converters are perfectly tuned for the operation of RZR centrifugal fans.
The use of the newest power semi-conductors guarantees high efficiency and minimum motor noise thanks to the especially fine pulse pattern.
See also the technical description "Performance".
Electric connection
Centrifugal fan systems are delivered ready for installation. The motor terminal box
can be easily accessed.
Electric installation must be carried out according to the applicable provisions in
compliance with local regulations. A terminal board circuit diagram showing correct
connection is enclosed with every motor.

Description
Performance
The curves show the total pressure rise pF as a function of the volume flow rate qV
plotted in a double logarithmical diagram. The throttle curves (system resistance
parabolas) are then represented by straight lines.
The curves are established with a reference density of r1 = 1.2 kg/m³ at the fan
intake.
The pressure and impeller input power are directly proportional to density r1.
Outlet velocity v2 and the dynamic pressure pd2 refer to the flanged cross section area
at the fan discharge.
psF = pF – pd2
The increase in static pressure psF when a duct is fitted to the discharge (Installation
B) can be calculated from the equation:
psF = pF – fpd × pd2
Where no duct is fitted (Installation A) there is no static pressure regain. The increase
in pressure psF can be calculated from formula:
The limits of application indicated in the fan curves (by blue dotted lines)
outline the recommended functional range of the fans, where a stable
operation with high efficiency can be expected.
The efficiency marked on the straight system lines is only applicable at the maximum
fan speed Nmax; it decreases with lower fan speed.

Efficiency ADH / AT / RDH
The performance curves Pr of the fan curve diagram correspond to the absorbed
power of the fan impeller.
The vertical scales shown at the right side of the diagram indicate the bearing power
loss Pb of the different fan executions and depending on the fan speed.
The resulting power absorbed on fan shaft is found by adding the absorbed power Pr
of the fan impeller and the bearing power losses Pb. As a consequence the resulting
fan efficiency is to be calculated according to the formula:
Efficiency RZR
The actual efficiency value for a fan speed lower Nmax is calculated by multiplying the
efficiency at Nmax by the factor fh for the appropriate speed. (fh to be found with the
scale on the right side of the page).
PN  Pa × fP
Motor nominal power ADH / AT / RDH / RZR
To determine the motor rating PN, the fan absorbed shaft power Pr must be increased
by a safety factor to accommodate belt drive losses and possible fan speed
differences.
The factor fp is an estimated value. As an approximate value, the figures below are
suggested.

When selecting the motor, the run up time must be checked whether being within
permitted limits.
The run up time can be worked out approximately according to the following formula:
where:
tA = run time in seconds
J = moment of inertia in kgm²
N = fan speed in rpm
PN = nominal motor power in kW
(Impeller weight and moment of inertia can be found on the performance diagram for
each fan size.)
If tA exceeds the motor manufacturer‘s recommendation or the tripping period of the
electrical gear, a larger motor must be used or the starting gear has to be selected for
heavy starting.

Description
Sound
Noise measurements are undertaken in accordance with DIN 45635-38 “Noise
Measurement of Machines: Fans”.
Induct Method for the Discharge
The induct method is specified with DIN EN ISO 5136. It determines the sound power
emitted at discharge of a test fan.
The test duct, as a main feature, is equipped with an anechoic termination fitted to
avoid end reflection going back into the duct.
Envelope Method – Free Inlet
The Envelope Method is described with DIN 45635-1 and -38, which specifies a
hypothetical box shaped measurement surface with several prescribed measurement
points.
1 = Air permeable sound screen
2 = Microphone positions for envelope method
3 = Test fan

The sound data of the fan curves are given as “A” weighted sound power levels.
A-sound power level RZR
The “A” weighted sound power level are identical for fan intake (LWA7) as well as for
fan discharge (LWA4).
LWA4 = LWA7 + LWrel4(A)
ADH / AT / RDH:
LWfc7 = LWA7 + LWrel7
LWfc4 = LWA7 + LWrel4
RZR:
LWfc7 = LWA4;7 + LWrel7
LWfc4 = LWA4;7 + LWrel4
A-sound power level ADH / AT / RDH
The “A” weighted sound power level (see curves) are apply for fan intake (LWA7). The
fan discharge sound power level LWA4 is obtained by calculating:
The correction value DLWrel4(A) is found with the table (left below) at the corresponding
fan curve page (ADH / RDH) by introducing fan speed and flow rate.
An approximation of the “A” weighted sound pressure levels LpA7/LpA6 at a distance
of 1 m may be obtained by subtracting 7 dB from the relative “A” weighted sound
power levels.
If should be noted that site acoustics, duct design, reverberation, natural frequencies
etc. can all influence noise to a greater or lesser extent.
For more accurate calculations to determine noise protection measures, the sound
power level in each octave band is of more value:
The noise correction data LWrel4 und LWrel7, in function of the fan speed and flow rate,
are to be found with the corresponding table on the fan curve page.
In some cases the noise level - calculated by this way - may in some cases be higher
than expected at the blade passing frequency.

Description
Sound
LWfc6 = LWfc4 + LWer
For a free discharge situation i.e. without duct connected the sound level will be lower
because of an end reflection.
This is specially true for low frequencies. For this case a correction may be applied to
LWfc4 of the first 3 octave bands as follows:

Explosion protection according to ATEX
Fans for use in explosive atmospheres must comply with EC Directive 94/9/EG
(ATEX 95). Equipment in Group II (all applications except mining) is categorised in
accordance with the required degree of safety for designated use in equipment
categories 1, 2 and 3. Depending on suitability, a distinction is in addition made
between G (gas, vapours) and D (dust).
Harmonised European standards and national guidelines must be observed.
Equipment in class 2 and 3 is not subject to compulsory specifications nor to type
testing. The manufacturer declares conformity with the EC directive.
For the standard designs of our fans, the following ignition sources are
essentially to be considered:
A Hot surfaces, e.g. due to heat of friction or seizure of a bearing or due to blockage
of an impeller
A Rubbing-, grinding- or beating sparks, e.g. as a result of contact of the impeller with
stationary components
A Sparks resulting from discharge of electrostatically loaded, non-conducting
omponents, e.g. of plasticpanels, surfaces with strong layer thickness.
Preconditions for operating:
A In the proximity of the motor, the temperature limits -20 °C and +40 °C must
not be exceeded.
A The temperature limits of -20 °C und +60 °C for the flow medium must not
be exceeded. If the temperature of the flow medium should exceed +60 °C
on the pressure side, then the fan must be switched off!
A The fans may only be employed with a horizontal shaft.
A The fans are to be protected against the falling-in or sucking-in of foreign
objects. Protection guards must be ordered separately as an accessories.
A On the machine plate the max. permitted fan speed is indicated.
A Fans for operation in ex-hazardous areas are marked as such on the
machine plate and they are accompanied by an EU conformity declaration
and with operation and maintenance instructions.
The operation and maintenance instructions have strictly to be observed.
The conformity is always related to the fan system supplied.
If the fan is completed with motor and belt drive by the customer the conformity of
this fan set has to be declared at new.
Fans of the series ADH / AT / RDH in ATEX-Execution on request.
