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.
To make the selection easier for our customers, we offer
complete systems as defined by the ErP Directive!
In order to compare the systems, the total efficiency ηe of the fan
without speed regulation is considered.
If the system has speed regulation, it will be taken into account with
the “part load compensation factor” Cc (see below):
without speed regulation: Cc = 1
with speed regulation Ped ≥ 5 kW: Cc = 1.04ATOS    QV-10/2    油壓傳動(dòng)閥
with speed regulation Ped < 5 kW: Cc = -0.03 ln(Ped) + 1.088
In order to take the speed regulation into account via the part load
compensation factor Cc, the following mathematical losses arise
in accordance with the formula prescribed by ErP for the following
typical motor powers:
Ped = 4.00 kW: Cc = 1.05 (5 %)
Ped = 2.20 kW: Cc = 1.06 (6 %)
Ped = 0.75 kW: Cc = 1.10 (10 %)

and with AC external rotor motors or brushless DC external
rotor motors.
Building blocks for best values
Thanks to the decades-long experience of Nicotra Gebhardt all the
components of our fans contribute to their high performance.
Impellers and blades are optimised for turbulence and therefore
particularly efficient. An example: With the latest development,
the RLM Evo impeller, the free-running centrifugal fans of
Nicotra Gebhardt achieve system efficiency grades never reached
before.
In addition, the brushless DC drives which Nicotra Gebhardt
offers for its direct drive fans improve the system efficiency grades.ATOS    QV-10/2    油壓傳動(dòng)閥

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

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.

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.
Flanges and Flexible Connections
Made from galvanized or painted steel, to connect ducts and system components to

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.
Measuring connector in inlet cone
Hose pipe to connecting piece in the side wall
Connecting piece (external diameter of 6mm) for the pressure
measurement
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.

The centrifugal fans are ideal for conveying clean air. The allowed air temperature
comes from -20 °C to +40 °C.
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

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!

Highest system performance and best energy efficiency
The RZP rotavent serie
Economic, quiet and compact.
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
setting unrelated to mains frequency – same operating point for 50/60 Hz
problrm free speed control from 0 up to 100 %
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.

Measurement category / Efficiency category = B / TOTAL
VSD power range at optimum Ped = 4.12 kW (<10 kW)
Efficiency grade according to ErP Directive N2015 = 64
Calculation of the ErP energy efficiency ηtarget required 2015:
ηtarget = 4.56 · ln(4.12) - 10.5 + 64 ηtarget ≈ 60.0 %
Fan energy efficiency ηe:
System efficiency (total) by proSELECTA II ηe ≈ 65.6 %
Calculation of the Fan efficiency grade "NF":
N
F = 65.6 - [4.56 · ln(4.12)] + 10.5 NF = 69.6
Result: ηe 65.6 % > ηtarget 60.0 % resp. NF 69.6 > N2015 64
The energy efficiency of the fan surpasses the requirements of the ErP for 2015.
A technical data list according to ErP-REGULATION 327/2011/EU of all fans is
available at the end of this chapter "RZP".

RZP 11-0200/-0400
The compact pioneering technology
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 brushless integral 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 efficiency
A 10% up to 20% better system efficiency is achieved in comparison
to similar performance data for voltage controllable fan systems.
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
