The overall picture will decide
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.
η e = P u(s) / P e
If the system has speed regulation, it will be taken into account with
the “part load compensation factor” Cc (see below):
η e = P u(s) / P e(d) · C c

ηe = Total efficiency
Pu(s) = Fan gas power when operating at the optimal
energy efficiency point
Pe = Electric input power when operating at the
optimal energy efficiency point
Ped = Input power of speed regulator when operating
at the optimal energy efficiency point
Cc = part load compensation factor
without speed regulation: Cc = 1
with speed regulation Ped ≥ 5 kW: Cc = 1.04
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 %)
Complete systems by Nicotra Gebhardt
Nicotra Gebhardt can supply complete systems in all product
categories which meet the ErP requirements. We offer highly efficient
fan systems
with matching components and “high efficiency drives” –
belt and direct drive.
with integrated or external control to regulate speed.
with IEC standard motors (IE2) or internal rotor motors with
brushless DC technology.
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.
The fan technology of Nicotra Gebhardt delivers highly
efficient systems for all applications.

Direct driven centrifugal fans / DDM / Description
These fans are intended to be incorporated into finished products for the treatment
of clean and filtered air, free of dust, particles, shavings, grease, etc., within the rated
ranges of temperature and electrical supply.
The design of the installation shall guarantee the essential safety requirements, as
specified by the locally enforceable legislation, including safety against human contact
with moving parts, e.g. by application of the design principles stated in EN ISO
12100.
When the inlet and/or outlet of a fan are connected to a ducting system, or to a
closed plenum, including integral filters or grids, these may be designed also to provide
the specified protection level.
Otherwise, the fan must be protected by fitting appropriate inlet or outlet guards,
designed in accordance with EN ISO 13857, available from Nicotra Gebhardt as
accessories or options.

Air performance ratings shown in this catalogue have been derived from performance
tests made with installation type "B", with free inlet and ducted outlet.
The performance data shall be obtained in a laboratory registered by AMCA for
AMCA 210/99 air performance testing. Data are not certified by AMCA.
Ratings are referred to the standard air density of r 1 = 1.2kg/m 3 at the fan inlet.
4 1 1.1 2 3 In the diagrams, the A-weighted housing and free inlet sound power level L WA7 is
given as the emission parameter for the ventilator.
The A-weighted noise level L pA7 for a distance of 1m (see sketch) is achieved approximately
in that the correction value given below is subtracted from the respective A
sound power level.
It should be noted that site acoustics, duct design, reverberation, natural frequencies
etc. can all influence noise to a greater or a lesser extent.

For a proper fan selection the duty point in the grey area to the left of the leftmost
dashed parabolic line drawn on each performance diagram should preferably be
avoided. In this area the fan stall is producing fluctuating pressure and fluctuating
loads on the fan and motor; some single-phase motors may also be overheating in
this low-load condition.
When the performance curves of a fan are cut to the right with continuous-line
parabola, a fan selection with the duty point located below of this parabola shall
be carefully avoided, because the drive motor would be overloaded and would be
overheating. Such an operating condition may be evidenced by a motor input current
exceeding the maximum rated value.

Speed regulation generally
Direct driven centrifugal fans / DDM / Description
The high level of manufacturing technology and the use of selected materials provide
a considerable fan operating lifetime.
In most applications, the fan components more subjected to wear are the motor
bearings.
The bearings are sized to reach, using 80% of the maximum allowed current and working
at an air temperature not higher than 40°C, a L 10h operating life of 20,000 hours.
This means a 7 years fan lifetime, for fans running 8 hours a day.
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.
Most motors have “F” ISO insulation class but some of the smaller models have
nevertheless “B” ISO insulation class.
Motors could have IP32; IP44; IP54 or IP55 protection class (closed frame) or IP10;
IP20 protection class (open frame).
Detailed information for each fan model are provided with fan specification on the
product pages.
All standard production motors are equipped with an integrated thermal overload
protectors (TOP), as protection against thermal overload.
TOP may be wired internally to windings and then they’ll automatically stop the motor,
if a overheating event occurs, and start the motor again once it is cooled down.
TOP may alternatively be externally wired, that means TOP terminals are available to
the user in the motor terminal block or terminal box.
In this case, the TOP terminals can be manually connected in series between power
supply and motor windings or, alternatively, to an external device that switches off the
mains to prevent that the motor be damaged by an overheating conditions.
All standard production motors can always be used with transformers or devices
which do not modify the sinusoidal wave line to change the fan speed is always
allowed.
Speed regulation for fans equipped with single-phase motors
Single or multiple speed available. Single phase motors are generally suitable for
speed regulation by changing the input voltage with our electronic single-phase RVM
speed regulators (see chapter "Options/Accessories" for further information).
The speed variable types are marked with an dot in the technical data tables.
The reduced – voltage curves shown in the catalogue may be obtained by either
using transformers or our RVM regulators. In the last case, we have commonly used a
2-wires connection for running currents up to 3 Ampere max and a 3-wires connection
for higher running currents.
Speed regulation of multi-speed fans is obtained by connecting the mains to the
correct motor terminals according to the wiring diagram supplied with each fan.
Speed regulation for fans equipped with three-phase motors
Single or double speed available. Performance diagrams of single speed fans usually
shows only the curve referred to a 230V star – 400V delta configuration.
Performance diagrams of double speed fans usually shows the curves referred to a
400V star (high speed) – 400V delta (low speed) configurations.
The use of RVT controllers or inverter is only acceptable with special motors equipped
with a reinforced insulation of the windings. In this case, these devices shall be in
accordance with the requirements of IEC / TS 60034-17:2006.

Direct driven centrifugal fans / DDMB / Description
These fans are intended to be incorporated into finished products for the treatment
of clean and filtered air, free of dust, particles, shavings, grease, etc., within the rated
ranges of temperature and electrical supply.
The design of the installation shall guarantee the essential safety requirements, as
specified by the locally enforceable legislation, including safety against human contact
with moving parts, e.g. by application of the design principles stated in EN ISO
12100.
When the inlet and/or outlet of a fan are connected to a ducting system, or to a
closed plenum, including integral filters or grids, these may be designed also to provide
the specified protection level.
Otherwise, the fan must be protected by fitting appropriate inlet or outlet guards,
designed in accordance with EN ISO 13857, available from Nicotra Gebhardt as
accessories or options.

Air performance ratings shown in this catalogue have been derived from performance
tests made with installation type "B", with free inlet and ducted outlet.
The performance data shall be obtained in a laboratory registered by AMCA for
AMCA 210/99 air performance testing. Data are not certified by AMCA.
Ratings are referred to the standard air density of r 1 = 1.2kg/m 3 at the fan inlet.

given as the emission parameter for the ventilator.
The A-weighted noise level L pA7 for a distance of 1m (see sketch) is achieved approximately
in that the correction value given below is subtracted from the respective A
sound power level.
It should be noted that site acoustics, duct design, reverberation, natural frequencies
etc. can all influence noise to a greater or a lesser extent.

These brushless DC external rotor motors (BLDC) are especially designed. They have
an highest efficiency also in the partial load area.
The motors are protected via safe operating area (SOA). SOA defines the conditions
(voltage, power, current, speed) over which the drive can be expected to operate
without self-damage. The SOA of the DDMB is automatically guaranteed by the motor
design and the controller settings. Additionally to that the motors are equipped with
thermo contact (PTO) to protect the motors against thermal overload.
The speed limits are defined by the presetting of the dip switches and the winding
configuration. Between that limits the speed can be controlled via analogue (0...5V or
0...10V) or MODBUS-interface.

Direct driven centrifugal fans / DDMB / Description
For a proper fan selection the duty point in the grey area to the left of the leftmost
dashed parabolic line drawn on each performance diagram should preferably be avoided.
In this area the fan stall is producing fluctuating pressure and fluctuating loads on
the fan and motor; some motors may also be overheating in this low-load condition.
When the performance curves of a fan are cut to the right with continuous-line
parabola, a fan selection with the duty point located below of this parabola shall
be carefully avoided, because the drive motor would be overloaded and would be
overheating. Such an operating condition may be evidenced by a motor input current
exceeding the maximum rated value.
The high level of manufacturing technology and the use of selected materials provide
a considerable fan operating lifetime. Only the motor bearings are subject to wear in
most applications. The calculated bearing life time L10h is appr. 30,000 hrs.
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.

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), RS485 serial interface as well as a detailed
operating instructions. Caution about combination with isolators (ESH)! Special EMCaction
can be necessary, furthermore do not switch during operation, overvoltages
can destroy the switch and the motor-winding.

Permitted ambient temperature during operation: -10°C up 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.
The selected frequency inverters (G110 und MM420) are units contains the
frequency inverter (as shown in the following tables) with the matching interference
suspression filter (Class B) and a control panel. A further component
is the line choke which is available as an accessorie. For more information the
available frequency inverters are shown in the following tables.

424
Direct driven centrifugal fans / Appendix / Accessories
Motor protection unit for three-phase current motors (standard motors) without thermal
contacts.
Design
Plastic casing in protection class IP55, permissible ambient temperature +40°C, 40Hz
up to 60Hz, 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 EUM33 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.

Direct driven centrifugal fans / Appendix / Accessories
Design
Beautifully shaped, shock-resistant plastic casing. Protection class IP44/IP65, for
sur-face mounting, switching symbols 0 and I. The isolator is fitted with connection
terminals that are very accessible and has a con-nection diagram glued in the casing.
The ESH21 up to 3kW is designed to IP44. It is equipped with an integrated lo-cking
mechanism.
The ESH21 up to 5.5kW is designed to IP65. It is equipped with a coupling cover
and an integrated locking mechanism. A padlock can in some cases be fitted to the
rotary switch.
Function
The isolator disconnects the fan safely from the mains in the event of cleaning, maintenance
or repair work on site and thus avoids accidents due to uncontrolled activation
of the unit by third parties. It is no main switch or emergency switch.
All of the classified isolators are fitted with potential-free contacts (1 closer
and 1 opener).
The isolators for motors with a built-in thermal contact have on principle three supplementary
auxiliary contacts, so that the pre-switched control device does not drop out
during cleaning or servicing work due to motor.
Caution about combination with frequency inverter!
Special EMC-action can be necessary, furthermore do not switch during operation,
overvoltages can destroy the switch and the motor-winding.
The isolators are grouped according to motor rated power. All important characteristic
data are evident from the model designation.
E.g.: ESH 21-0030-65 = 3kW switch - 6 main contacts - 5 auxiliary contacts
