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.
he = Pu(s) / Pe
he = T otal efficiency Pu(s) = Fan gas power when operating at the optimal
energy efficiency point
Pe
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.
=E lectric input power when operating at the
optimal energy efficiency point
If the system has speed regulation, it will be taken into account with the “part load compensation factor” Cc (see below):
ηe = Pu(s) / Pe(d) · Cc
Nicotra Gebhardt can supply complete systems in all product categories which meet the ErP requirements. We offer highly efficient fan systems A with matching components and “high efficiency drives” – belt and direct drive. A with integrated or external control to regulate speed. A with IEC standard motors (IE2) or internal rotor motors with brushless DC technology. A and with AC external rotor motors or brushless DC external rotor motors.
The fan technology of Nicotra Gebhardt delivers highly efficient systems for all applications.
Ped = Input power of speed regulator when operating at the optimal energy efficiency point Cc = part load compensation factor
without speed regulation: with speed regulation Ped ≥ 5 kW: with speed regulation Ped < 5 kW:
ηe
Cc = 1 Cc = 1.04 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 %)

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
The benefits of rotavent RZM The high value and precisely manufactured components of rotavent, manufactured with most modern machinery for demanding tolerance standards, are the basis for a product range satisfying highest quality requirements. Version

Fittings / Accessories 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.

Fittings / Accessories Anti Vibration Spring Diffusers 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 AVMs 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. The AVMs are supplied with the suitable mounting material for the base frame (CC- or U-Profiles). Anti Vibration Spring Diffusers

Standard-calibration faktor K10 <10 % 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.

Description 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 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.
Performance data The curves show the total pressure rise pF as a function of the volume flow rate qV plotted in a double logarithmical diagram. The throttle curves (system resistance parabolas) are then represented by straight lines. The curves are established with a reference density of r1 = 1.2 kg/m³ at the fan intake. The pressure and impeller input power are directly proportional to density r1. Outlet velocity v2 and the dynamic pressure pd2 refer to the flanged cross section area at the fan discharge. The increase in static pressure psF when a duct is fitted to the discharge (Installation B) can be calculated from the equation: psF = pF – pd2
Where no duct is fitted (Installation A) there is no static pressure regain. The increase in pressure psF can be calculated from formula: psF = pF – fpd × pd2
The limits of application indicated in the fan curves (by blue dotted lines) outline the recommended functional range of the fans, where a stable operation with high efficiency can be expected. The efficiency marked on the straight system lines is only applicable at the maximum fan speed Nmax; it decreases with lower fan speed.

Direct driven centrifugal fans / RZM / Description
Description 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 (LWA4). An approximation of the “A” weighted sound pressure levels LpA7/LpA6 at a distance of 1m at fan Inlet or discharge may be obtained by subtracting 7dB 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. Inlet side: Discharge side:
LWfc7 = LWA4/7 + LWrel7 LWfc4 = LWA4/7 + LWrel4
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. In some cases the noise level - calculated by this way - may in some cases be higher than expected at the blade passing frequency.
N×z fBP =— 60
LWfc6 = LWfc4 + LWer
Blade passing frequency fBP = Blade passing frequency in Hz N = Fan speed in 1/min z = Number of blades For a free discharge situation i.e. without duct connected the sound level will be lower because of an end reflection. This is specially true for low frequencies. For this case a correction may be applied to LWfc4 of the first 3 octave bands as follows: RZM ..-
