ηe = Pu(s) / Pe
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 = 1.04
� 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 %)
Efficiency grade “N” to ErP-Directive
Ped = Input power of speed regulator when oper-ating at the optimal energy efficiency point
Cc = part load compensation factor
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.

015 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.
Simple and reliable selection
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.
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.

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.

DescriptionDirect driven centrifugal fans / DD / Description
Fan lifespanThe 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 wor-king at an air temperature not higher than 40°C, a L10h operating life of 20,000 hours. This means a 7 years fan lifetime, for fans running 8 hours a day.
MediaThis 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.
MotorsMost 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.
Motor protectionAll 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.
Speed regulation generallyAll 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 motorsSingle 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 connec-tion 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 motorsSingle 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.

Frequency converterDesignFrequency inverter with variable output voltage and frequency, specially designed for the operation of centrifugal fans with induption motors. Due to the use of modern po-wer 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 EMC-action can be necessary, furthermore do not switch during operation, overvoltages can destroy the switch and the motor-winding.

Permitted am-bient 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 (residential and commercial uses) is integrated into the package as subst-ructure 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)15kW to 250kW rated motor power, 380V to 480V 10% three-phase AC, 47Hz up to 63Hz, three-phase current output 3×400V AC, protection class IP20.Permitted ambient temperature during operation: -10°C up to +50°C. The interfe-rence suppression filter required to comply with the EMC basic interference suppres-sion standard EN 50081-1 (industrial applications) is partially integrated. In order to at-tain 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 addi-tional 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 interfe-rence 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.

Isolator ESH 21
Isolator ESH 21 (≤ 3kW) Isolator ESH 21 (≥ 5.5kW)
DesignBeautifully 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.
FunctionThe isolator disconnects the fan safely from the mains in the event of cleaning, main-tenance or repair work on site and thus avoids accidents due to uncontrolled activati-on 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 supple-mentary 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

Isolator ESH 22DesignShock-resistant metal casing, black switch with symbols 0 and I. Protection class IP65 or IP54, for surface mounting (see determination in the tabular).The isolator is fitted with connection terminals that are very accessible and has a connection diagram glued in the casing.All isolators are equipped with a coupling cover and an integrated locking mecha-nism. In some cases a padlock can be fitted to the rotary switch.
FunctionThe 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 supple-mentary auxiliary contacts,so that the preswitched control device does not drop out during cleaning or servicing work due to motor.
UseThe isolator ESH22 with metal casing is necessary, if screened components must be used. (e.g. frequency inverters or control engineering devices are used featuring electronic components).
Attention!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 22-0075-65 = 7.5kW switch, 6 main contacts, 5 auxiliary contacts.
