Frequency Inverter Parameters
The following curves show the fans operating with frequency control:
The nominal frequency of the inverter is 87 Hz, i.e. the input frequency
400 V is increased to 87 Hz. The performance curves plot speed/frequency against volume and pressure, and the total efficiency
(ηinverter × ηmotor × ηimpeller) is expressed as a parabola.
The set up parameters for each inverter are provided in the accompanying literature.

Drain Plug
If the fan is installed outside, or if conveying a medium containing humidty, condensation of water may accumulate inside the fan scroll.
For extraction of this water a condense water drain has to be installed at the lowest
point of the scroll. The drain will be provided with a thread R1/2" for connecting it to
a piping.
At order please indicate the required casing position.
Inspection Door
For the purposes of maintenance and cleaning there is an opening, which can be
securely closed by means of an access door, in the fan casing.
As it can only be opened with a tool, the access door complies with safety and
accident prevention regulations. Additional securing with locking bars can be supplied
on request.
The site and orientation of the inspection opening depends on the casing position.
The position should be specified when ordering according to the following diagram:

Anti Vibration Rubber Buffers
Anti Vibration Mounts (AVM) are designed to prevent noise and vibrations being
transmitted through the base of the fan. AVMs should be mounted beneath the fan
base frame so the weight and spring deflections are evenly distributed.
They should not be mounted symmetrically around the centre of gravity of the system
when idle, 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.
Rubber buffers
for both vibration and noise insulation at fan speeds above 1400 rpm or 850 rpm
Rubber buffers
for noise insulation only at fan speeds under 800 rpm or 1700 rpm

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.

Volumeter
With the flow measuring device it is possible to easilymeasure / 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.
volume flow qV [m3/h]
calibration factor K [m2s/h]
density of media r [kg/m3]
pressure difference at cone DpDü [Pa]
In order to calculate the flow rate, a calibrating factor "K" is required. This factor is
determined by comparativemeasurement on a standard test rig.
Calibration factors
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.

Volume flow determination
With the represented chart and a measured difference pressure at the nozzle can
streamed determined become the volumes in the indicated density. The chart can be
used also to the determination of the needed pressure area of a manometer. In addition the difference pressure is determined at the nozzle for the maximally appearing
volume current with the chart.

Description
Performance data
The performance curves of the fans are determined at the plenum test rig according
to ISO 5801.
The curves show the pressure increase for a fan with free discharge as a function of
the flow rate. The diagramme scale is a double logarithmical net.
The throttle curves (system resistance parabolas) are then represented by straight
lines.
All fan curve and related data are based on a reference density of r1 = 1.15 kg/m3 for
the conveyed medium at fan intake.
For a medium density r1 different to this standard value the fan curves and the motor
load, as a consequence, will be changing.
The efficiencies and power consumption given in the performance curves include all
losses due to the motor and the frequency converter unit.
The data are established for a fan with free discharge i.e. without duct connection at
the presurre side, installation A.
Sound
Sound measurement and analysis are carried out in accordance with DIN 45635-38
”Sound measurement at machines; fans”.
The sound data of the fan curves are given as “A” weighted sound power levels LWA.
The “A” weighted sound power level are identical for fan intake (LWA7) as well as for
fan discharge (LWA6).
An approximation of the “A” weighted sound pressure levels LpA7/LpA6 at a distance
of 1 m at fan Inlet or discharge 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, in function of the fan speed and flow rate, are to be found
with the corresponding table on the fan curve page.
Inlet: LWfc7 = LWA6/7 + LWrel7
Discharge: LWfc6 = LWA6/7 + LWrel6
In some cases the noise level - calculated by this way - may in some cases be higher
than expected at the blade passing frequency.

Motors
The specially developed integral motors are designated as having protection class
IP54 and heat class F.
They are optimised to a high rate of efficiency, with speed that can be adjusted
between 0 and 100 % via the frequency inverter.
The motors are fitted with an easily accessible metal clamping box. To prevent
overloading, PTC are inserted in the windings of the motors. In conjunction with
PTC release equipment or a frequency inverter with PTC connection, effective motor
protection is guaranteed.
The motors ex works are in star connection (Y). When operating with a
frequency inverter, the links must be placed in delta connection (g) (see
wiring diagram).
Electric connection
All fans are delivered ready for connection. Electrical connection takes place in
accordance with the enclosed operating instructions and observing the relevant
applicable local regulations and directives. Every fan is accompanied by a connection
circuit diagram. You can also find the relevant circuit diagram online at:
www.nicotra-gebhardt。。ｃｏｍ.
Frequency inverter operation
Frequency inverter operation with a nominal voltage of 400 V the edge frequency of
87 Hz must be set. The motor must then be delta (g) connected.
The inverter exit voltage is a square function of the frequency and the voltagefre-quency-curve has a corresponding shape. In the case of direct mains (400 V)
operation the motor should be star (Y) connected.
If frequency inverters are allocated by the customer, then it must be ensured that the
voltage gradient of the frequency inverter does not exceed the figure of 500 V/μs
and the maximum peak voltage at the motor terminals is kept to 1200 V. Depending
on the frequency inverter employed and the length of cable between the frequency
inver-ter and the motor, additional units (such as motor choke, active sinus filter, for
examp-le) may be needed to ensure that the limits named above are kept to.
Non-compliance may lead to damage to the motor!

Through the combination of two pioneering technologies - the aerodynamics of the
rotavent impeller combined with energy efficient brushless integral motors, Nicotra
Gebhardt has developed a series of controllable direct drive centrifugal fans setting
new standards for economy and quiet operation.
Your benefits:
a greater motor efficiency due to the elimination of all slip losses and marked
reduction in copper losses
a compact range of fans from using built-in brushless DC motors (no belt drives)
maintenance and wear free drive (no V-belts)
short payback time due to high energy saving, especially with long operating
periods
higher comfort levels through particularly low noise fans and motors

reduced motor heat from higher motor efficiency – reduced energy expenditure for
the cooling systems
System efficiency
The given System Efficiency is the efficiency of the whole system and includes the
individual efficiencies of the component Fan – Motor – Control electronics.
ErP conformity
Depending on the model of the fan, the efficiency grade "N" set in accordance with
the ErP Directive must be achieved from 2013 and 2015 respectively.
The efficiency grade designates a parameter in the calculation of the target energy
efficiency of a fan depending on the electric input power when operating at the
optimal energy efficiency point. The figure of parameter "N" corresponds to the target
energy efficiency with a power of 10 kW.

All options and accessories must be specified separay.
Please take the technical data and dimensions from the corresponding page of the
catalogue.
Drain Plug
If the fan is installed outside, or if conveying a medium containing humidty, condensation of water may accumulate inside the fan scroll.
For extraction of this water a condense water drain has to be installed at the lowest
point of the scroll. The drain will be provided with a thread R1/2" for connecting it to
a piping.
At order please indicate the required casing position.
Inspection Door
For the purposes of maintenance and cleaning there is an opening, which can be

As it can only be opened with a tool, the access door complies with safety and
accident prevention regulations. Additional securing with locking bars can be supplied
on request.
The site and orientation of the inspection opening depends on the casing position.
The position should be specified when ordering according to the following diagram:
e.g. Access door, Pos. 2.

Anti Vibration Rubber Buffers
Anti Vibration Mounts (AVM) are designed to prevent noise and vibrations being
transmitted through the base of the fan. AVMs should be mounted beneath the fan
base frame so the weight and spring deflections are evenly distributed.
They should not be mounted symmetrically around the centre of gravity of the system
when idle, 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.
Rubber buffers
for both vibration and noise insulation at fan speeds above 1400 rpm or 850 rpm
Rubber buffers
for noise insulation only at fan speeds under 800 rpm or 1700 rpm
Dimensions in mm, subject to change.
Volumeter
With the flow measuring device it is possible to easilymeasure / 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.
volume flow qV [m3/h]
calibration factor K [m2s/h]
density of media r [kg/m3]
pressure difference at cone DpDü [Pa]
In order to calculate the flow rate, a calibrating factor "K" is required. This factor is
determined by comparativemeasurement on a standard test rig.
* A = for U-profile; C = for CC-profile
Calibration factors
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.

Safety
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

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.
Performance data
The performance curves of the fans are determined at the plenum test rig according
to ISO 5801.
The performance curves show the unrestricted outlet pressure increase psF of the fan
as a function of the volume flow.
For ease of use, equipment parabolas are included in the diagrams. It should be
noted that the efficiency varies with the controller position on the curve. For the
con-troller positions 100 % the efficiency is shown on the per-formance curve at the
points.
All the given characteristics are based on a density r1 for the conveyed medium at
the fan entry of 1.15 kg/m3.
Pressure increase and drive output vary proportionally with the density r1.
The free discharge pressure increase psF is the usable static pressure increase of the
fan.
The given data is applicable to free discharge installation "A" only.
The performance curves given in the catalogue only apply for the application of the
Commutation Unit and the given nominal voltage.
The efficiencies and power consumption given In the performance curves include all
losses due to the built-in motor and the electronic commutation unit.
Sound
Sound measurement and analysis are carried out in accordance with DIN 45635-38
"Sound measurement at machines; fans".
The sound data of the fan curves are given as "A" weighted sound power levels LWA7.
The "A" weighted sound power level are identical for fan intake LWA7.
An approximation of the "A" weighted sound pressure levels LpA7/LpA6 at a distance
of 1 m at fan Inlet or discharge 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, in function of the fan speed and flow rate, are to be found
with the corresponding table on the fan curve page.
Inlet: LWfc7 = LWA7 + LWrel7
Discharge: LWfc6 = LWA6 + LWrel6
In some cases the noise level - calculated by this way - may in some cases be higher
than expected at the blade passing frequency.

Direct driven centrifugal fans / RZP / Description
Description
Media
This range of fans are specially designed for use into air handling units (AHU) and
ventilation systems.
The centrifugal fans are ideal for conveying clean air. The allowed air temperature
comes from -20 °C to +40 °C.
Motors
The motors do not have direct temperature monitoring through termistors or probes.
Motor protection is achieved through the current monitoring of the electronic
commutation unit.
Attention!
In no case may the fan be driven with a larger output electronic commutation
unit than the one indicated in the catalogue or be used in a conveyor medium
temperature greater than the maximum permitted one.
Electric connection
The fans will be delivered ready for installation and are fitted with a connection cable
or an easily accessible motor connection box.
The electrical installation is to be carried out in accordance with the applicable
conditions and in observance of local regulations.
Each motor is accompanied with a terminal connection diagram which clearly shows
the correct connections.
All motor and position sensor leads must be screened!
Recommended cable e.g. Fabrikat Oilflex 100-CY from the Lapp Co.
Basically the operating instructions of the Electronic Commutation Unit are to be
observed.

The powerful high technologie!
Optimal aerodynamics
Low turbulance velocity for both inlet and discharge due to the large
free cross section and minimal flow restraint of the impeller, an example of aerodynamics and performance of the rotavent.
Acoustics
Reduction of high frequency noise levels is just one of the advantages
of the rotavent, together with optimised AC-motors.
Minimal sound levels due to low blade passing frequencies from the
optimised impeller geometry of the rotavent. The impeller has obliquely
inclined blades with trailing edges, and the throat plate is inclined
opposingly.
High efficiencies
Nicotra Gebhardt fans of the RZM rotavent range are operating at high
efficiency in wide area of the fan curve.
Wear-free drive by direct coupling
The use of direct coupling drive avoids wear of the drive as this is the
case with belt driven fans.
Your benefits:
negligible sensitivity to built in disturbances
minor pressure loss with free discharge operation
smaller, yet greater energy performance
Your benefits:
reduced size and costs of attenuation and silencers
Your benefits:
low running costs
high efficiency
Your benefits:
no subsequent filter necessary
less dust in the system
