Simple and reliable fan selection
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.
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:
• The complete configuration of your fan with its associated system
accessories and belt drive layout.
• The possibility to produce fans that operate via a frequency
inverter.
• The option of saving your own fan configuration on our server.
• The opportunity to modify your saved configuration, even over the
phone to your Nicotra Gebhardt representative.

The silent unit
There are cases where a fan has to be silent first. It is
for cases like this that the FDA 31 has been designed.
A casing equipped with highly efficient lining reduces
the discharge sound level.
The cubic design of the steel casing in addition integrates the unit into any roof surrounding. This is the
reason that thousands of these units are doing their
job without drawing attention. Perhaps on one of your
roofs soon too …

Determination of the Octave level
For more exact calculations when determining the required attenuation, the sound
power level in the octave bands is important.
LWfc 3 = LWA + LWrel 3
LWfc 8 = LWA + LWrel 8
The relative sound power levels for inlet and discharge sides, at various duty points,
can be read from the corresponding tables.
LWA3 = LWA8 + 11 dB
Inlet side
Relative sound power level for inlet side LWrel3 at octave centre frequencies fm [LWrel3 = LWfc3 - LWA3]

Inlet silencer
ZDR 30-0250/-0710
The tubular inlet silencer has a square flange on the side nearest to the roof unit, for
bolting to the respective flat roof upstand. It slides inside the upstand, while the opposite end can take either additional ducting or an inlet cone.
The exterior skin is made of galvanised sheet steel, and the interior of galvanised perforated plate, the cavity between them is filled with non-flammable acoustic material.
There is no central core of material, so that any pressure loss will be insignificant.

Automatic shutter
ZLK 01-0180/-0710
ZLK 03-0225
Automatic shutters ZLK 01 are working as back draught dampers at stand still of the
roof fan thus avoiding uncontrolled intake of cold air.
Due to turbulences generated by the back draught damper ZLK the sound data for
intake and discharge may increase of app. 3 dB at discharge when a damper is fitted.
Motor drive shutter
ZLK 21-0250/-0710
Motor actuated shutters ZLK 21 control the exhaust air stream (mechanically or
naturally generated) also if the fan is not in operation. This is true also for ventilation
hoods. The shutter opens when the fan is switched on and closes at stop of the latter.
When working in parallel with the fan the shutter is working like a non motorised one.

It is recommended to provide an intermediate duct piece between fan and shutter.
For this case the indicated pressure drops are applicable. If the shutter is directly fitted after the roof fan, higher pressure drops have to be expected.
The Motor drive shutter ZLK 21 is not available for ATEX fans (Type RGA 31-.....X-3G)!
A short circuit proof, single phase, actuator draws the shutter flaps by highly resistant
nylon ropes to open position and stays switched on during the whole opening phase.
The system is not equipped with end switches which could get dirty and ineffective
during live time.
After being switched off a push back spring closes the shutter.
The actuator has to be electrically connected to the main fan relay enabling the shutter to be opened at every time when the fan is put into operation. An auxiliary contact
for closing is not necessary.
When providing an motorised shutter it is recommended to fit an intermediate duct
piece between fan and shutter in order to facilitate access to the shutter actuator.

for three-phase current motors (standard motors)
without thermal contacts
Design
Plastic casing in protection class IP 55, permissible ambient temperature +40 °C,
40 Hz – 60 Hz, frontal operation, for wall mounting. Motor protection unit for singlespeed, non- variable speed three-phase current motors without thermal contacts.
Function
The motor protection units must be adjusted on site to the trigger current.
If the preset trigger current is exceeded, the device disconnects the motor from the
mains supply via a thermal overload release. Pressing the “on key” causes the unit to
turn on again.
All motor protection units EUM 33 are also suitable for the protection of EExe-motors
(PTB-Prüfung Gesch-Nr. 3.35/386.3060). They must however be mounted outside of
explosion endangered areas, since they are not themselves designed with explosion
protection.

ESM 01-/11-/12-/13-
for motors with fitted thermal control sensors
(thermal contacts, PTC)
Design
Beautifully shaped plastic casing made of shock resistant polystyrol, protection class
IP 54.
All units are suitable for wall mounting and include: hand switches for frontal operation, operational signal lamp and control safety accessible from outside.
Permissible ambient temperature: +40 °C.
Function
Should the motor winding temperature rise excessively, the imbedded motor winding
thermal contact or PTC will open the control circuit, causing the mains relay to drop
out and thus disconnect the motor from the mains supply.
The motor will also be turned off in the case of a mains-side dropout of the control
phase, as well as if the contacts fail or if the mains supply is interrupted.
The motor protection units are not equipped with an automatic re-poweron after a
mains voltage failure and are thus fail-safe.
After the motor windings have cooled down, a lock-out device in the relay circuit prevents the motor from switching itself on. The hand switch must first be momentarily
turned to the 0-position and then back to the ‘on’ position.
The operational signal lamp indicates the operation of the motor. It goes out in the
case of a malfunction.
The motor protection units are suitable for group switching, i. e. several motors with
the same switching can be connectedto a common switchingdevice.
The sum of the motors’ rated power may not exceed the maximal device rated power. The thermal contacts of all motors are to be switched in series. The PTCs switched in series may not exceed the sum of 6.

ETH 31-/35-/36-/37-
transformatic, 5-step, with casing
Design
Completely plastic casing in protection class IP 54, Type:
ETH 31, 35 and ETH 37-0010/-0020-8D.
Painted metal casing in protection class IP 23, Type:
ETH 36 and ETH 37-0040/-0070-8D.
All units are suitable for wall mounting and include: speed control via hand switch
with 0-position and 5 switching steps, operating signal lamp, 230 V output for e. g. a
solenoid valve.
Permissible ambient temperature: -25 °C up to +40 °C.
ETH 31
These units include no motor protection unit. Protection switches for thermal contact
connections are to be laid in the conductor between the control device and the motor.
In Nicotra Gebhardt externallymounted rotor motors, the thermal contacts are already
bound into the motor winding.
ETH 35, ETH 36, ETH 37
These units possess a motor protection installation for thermal contact or PTC connection with a supplementary warning signal lamp, a potential-free exchanger and a
potential-afflicted (230 V) room thermostat connection (remote on – off).
Function
For motors with built-in thermal contacts, these open the control current circuit when
the permissible winding temperature is exceeded (ETH 31, 35, 36). Motors equipped
with PTC thermistor give an electrical signal to the trigger unit (ETH 37) when the temperature exceeds the default value. The trigger controls the main relay thus cutting
the motor feed. This causes the main fuse to fall out and disconnect the motor from
the mains.
After the motor winding has cooled down (ca. 2 Min.) or after remedying the cause of
the malfunction, respectively, turn the main switch temporarily to the 0-position and
then back to the operational position.

Frequency inverter
G110
MM420
Design
Frequency inverter with variable output voltage and frequency, specially designed for
the operation of centrifugal fans with induption motors.
Due to the use of modern power semiconductors it is possible to achieve a speed of
revolution with high efficiency.
Switching frequencies up to 16kHz can be set with all types. If the highest switching
frequencies are required (for example for reasons of noise reduction), the maximum
output current is decreased, in which case the performance category should be specially checked.
The overall package includes the frequency inverter, filter for class B (for residential and commercial uses) as well as a control unit.
General Performance characteristics
Motor protection feature for motors with thermistor temperature sensors, adjustable
accelaration and deaccelaration ramps, minimum and maximum rotation speeds,
fixed rotation speeds, trapping switch during operation, programmable inputs and
PI-controller (MM420 and MM430 only), RS 485 serial interface as well as a detailed
operating instructions.
Caution about combination with isolators (ESH)!
Special EMC-action can be necessary, furthermore do not switch during operation,
overvoltages can destroy the switch and the motor-winding.
Performance range G110 1AC 230V
(for single-phase AC supply)
0.25 to 2.2 kW rated motor power, 200 to 240V ±10% single-phase AC, 47 to 63Hz,
three-phase current output 3 × 230V AC, protection class IP 20.
Permitted ambient temperature during operation:
-10 °C to +40 °C.
Performance range MM420 3AC 400V
(for three-phase AC supply)
0.55 to 11kW rated motor power, 380 to 480V ±10% three-phase AC, 47 to 63Hz,
three-phase current output 3 × 400V AC, protection class IP 20. Permitted ambient
temperature during operation: -10 °C to +50 °C. The interference suppression filter
required to comply with the EMC basic interference suppression standard EN 500811 (residential and commercial uses) is integrated into the package as substructure
option. Power choke to comply with EN 61000-3-2 as additional component.
Observe performance reduction when using high clock frequencies!
Performance range MM430 3AC 400V
(for three-phase AC supply)
15 to 250kW rated motor power, 380 to 480V ±10% three-phase AC, 47 to 63Hz,
three-phase current output 3 x 400V AC, protection class IP 20.
Permitted ambient temperature during operation: -10 C to +50 °C. The interference
suppression filter required to comply with the EMC basic interference suppression
standard EN 50081-1 (industrial applications) is partially integrated. In order to attain
EMC requirements Class B a frequency inverter without filter should be selected. The
appropriate EMC-B filter is then required as an additional component.
Observe performance reduction when using high clock frequencies!

The indicated ratings of the units are made for a quick selection. The exact dedication of an inverter in this catalogue is made by taking into account of the max. admitted current at a pulse frequency of 4kHz. It is important to know that at higher pulse
frequencies the supplied current of the inverter will be decreasing, with the possible
consequences of having to select a larger inverter unit. Also longer feed lines or additional radio frequency filters may lead to the choice of a larger inverter size.

Description
Drive types
Nicotra Gebhardt external-rotor motors
Integrated motors that have proved themselves in practice are used for the drive.
Deep groove ball bearings that have been checked to be quiet and maintenance free
ensure a long service life.
To protect against thermal overload, all motors are equipped with thermal contacts.
This thermal overload protection must be effective during operation in order for the
factory guarantee to apply in case of damage. Please be sure to study the associated
circuit diagram for the fan regarding the technical inclusion of thermal contacts, also
available online at www.nicotra-gebhardt.com.
IEC standard motors
The standard fan drive consists of flanged IEC motors, execution B5, protection class
IP 55, heat class F. There is single-speed, multi-speed, and speed controlled motors
available.
According to their execution the motors are equipped with either PTC thermistors
or with thermo contacts as a standard. Only roof fan series „KD“ and „HD“ are not
equipped with PTC thermistors or thermo contacts. In connection with a triggering
unit, a motor protection unit, or a speed control unit with integrated protection, each
fan drive will be protected against thermal overload.
This thermal overload protection has to be in place and to be effective during operation in order to make the warranty applying in case of damage.
Please respect the instructions of the wiring diagram supplied with every fan. If these
instructions are missing they can be down loaded from www.nicotra-gebhardt.com.
Brushless-DC-motors with commutation unit
Brushless-DC-motors are DC motors that make use of developments in semiconductor technology to attain optimum use of energy, even in partial load operation.
With that Brushless-DC-motors provide the drive with the greatest energy efficiency
for fans. As the motor is operated as a standard with performance electronics, it is
predestined from the start for speed regulation. No other fan drive provides a comparable efficiency in the partial load area.
The motors do not have any direct temperature monitoring by thermal contacts or
thermistors. Motor protection is via current monitoring contained in the electronic
commutation unit.
The single-phase supplied commutation unit with variable output voltage and frequency is optimal coordinated with the operation of the Nicotra Gebhardt BrushlessDC-motors.
Explosion-proofed Version (ATEX)
The use of electronic controllers and inverters for speed control of explosion
proofed emotors is non admissible!
explosion proofed external-rotor-motors
Only proven external rotor motors of protection class IP 44 and insulation class F are
used. The motors are equipped with maintenance free closed groove ball bearings
lubricated for lifetime. They comply to ignition type EEX e II T3 (increased safety „e“,
according to EN 60079-7, EC certification labelled II 2G EEx e II T3) and certified for
temperature class T1 to T3. The motors are suitable for operation in explosion hazard
areas of zone 2.
The fan speed can be reduced by voltage using a transformer for reduction. The feed
voltage may not be lower than 115 V. (admitted range 115 V to 400 V).
In order to protect the motors against overheating PTC thermistors are provided. The
PTC unit has to be connected to a ATEX certified PTC switch labelled Ex II (2)G.
explosion proofed IEC Standard motors
The drive is realised with flanged standard motors type B5, protection class IP 55 and
thermal class F (used to B). They comply to ignition type EEX e II T3 (increased safety
„e“, according to EN 60079-7, EC certification labelled II 2G EEx e II T3) and certified
for temperature class T1 to T3.
In order to maintain the explosion safety level in operation, suitable overcurrent protection has to be provided.

Description
Sounds
At the fan curves the emission value of the A-weighted sound power level LWA is given
and are valid for both inlet (LWA3) and discharge (LWA8).
For the fans RDA/RDM, the sound values of the integrated discharge dampers are
considered.
For more exact calculations when determining the required attenuation, the sound
power level in the octave bands is important.
The relative sound power levels at intake and discharge, at various duty points, can
be read from the corresponding tables for each fan range.
LWfc = LWA + LWrel
The sound power level is the specific and objective noise parameter for every
machine. Only with these data sound comparisons between machines can be
made. For this reason only sound power level data are shown.
For fans classified to tolerance class 2 according to DIN 24166 a maximum deviation of the sound power level value of 4 dB is specified.

Often the sound pressure value at a determined distance from a fan is required. In
fact this value depends from surrounding conditions (reflections, absorption, sound
propagation possibilities).
The sound pressure level at a distance of 4 meters can for instance be lower of 16 to
23 dB to the corresponding sound power level.
The A-weighted sound pressure value LpA to be expected at a certain distance from
the fan can be evaluated approximately with the adjacent diagram.
The diagram shows 2 curves covering the field where the relative sound power level
data at various distances usually is situated. For a sound propagation in a hemisphere
shape and without reflections the curve “a” can be used. For more uncertain conditions – usual in practice – the use of the curve “b” is recommended.
The determination of the sound pressure at fan intake can only be made if the local
acoustic properties are known. (see z.B. VDI-Richtlinie 2081).
