2 The overall picture will decide Complete systems by Nicotra Gebhardt Depending on the model of the fan, the efficiency grade N set in accordance with the Er Directive must be achieved from 213 and 215 respectively. Efficiency grade N to Er-Directive Year Centrifugal fans with backward curved blades without housing static 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 1 kw. To make the selection easier for our customers, we offer complete systems as defined by the Er Directive! n order to compare the systems, the total efficiency η e of the fan without speed regulation is considered. h e = u(s) / e with housing static total Centrifugal fans with forward curved blades with housing static total h e = Total efficiency u(s) = Fan gas power when operating at the optimal energy efficiency point e = Electric input power when operating at the optimal energy efficiency point f the system has speed regulation, it will be taken into account with the part load compensation factor C c (see below): Nicotra Gebhardt can supply complete systems in all product categories which meet the Er 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 EC standard motors (E2) or internal rotor motors with brushless DC technology. and with C 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. mpellers and blades are optimised for turbulence and therefore particularly efficient. n example: With the latest development, the RLM Evo impeller, the free-running centrifugal fans of Nicotra Gebhardt achieve system efficiency grades never reached before. n 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. η e = u(s) / e(d) C c ed = nput power of speed regulator when operating at the optimal energy efficiency point C c = part load compensation factor without speed regulation: C c = 1 with speed regulation ed 5 kw: C c = 1.4 with speed regulation ed < 5 kw: C c = -.3 ln( ed ) η e n order to take the speed regulation into account via the part load compensation factor C c, the following mathematical losses arise in accordance with the formula prescribed by Er for the following typical motor powers: ed = 4. kw: C c = 1.5 (5 %) ed = 2.2 kw: C c = 1.6 (6 %) ed =. kw: C c = 1.1 (1 %) C c η m η T η r e(d) e u(s)

4 Nicotra Gebhardt technologies like... utomated manufacture of compact scroll and impeller with forward curved blades Own C and Brushless-DC motor production for optimal tuniung of motor and fan! proselect Simple and reliable selection proselect is a technical selection program that allows you to configure your own individually designed fan. t provides you with the opportunity to choose from the entire range of fan types and their associated options. The result from proselect is the provision of all the technical data for your fan, including sound level data, dimension specifications and accessories. part from that, as a registered user, your purchase prices are provided. dditionally fully dimensioned drawings in dxf format are available, which can be downloaded and transferred straight into your CD system. So that you can be sure. Models and options that are technically not permissible, are automatically excluded in proselect. So there is no chance that you will configure a wrong device option. You can register as a proselect 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. 2

6 The best fan for your application! DDM range direct driven fans Direct driven centrifugal fans of DDM range with forward curved impeller directly mounted on the external rotor motor are the ideal solution for your applications in the HVC business. The fact of manufacturing by ourselves each fan component the casing, the impeller and motor enables us to create fans that perfectly meet the requirements of high performances and low power consumptions. The wide range of different versions and motor types allows you to find the fan exactly matching what you really need. You anyway get the generally recognized advantages of the direct drive technology : Maintenance free No transmission losses Long fan life time High reliability Low operating costs nd, more, all the additional product advantages of the DDM range are at your fingertips. Compact casing erodynamically optimized in terms of both airflow and design, scrolls are made of galvanized steel and automatically assembled using an innovative procedure, providing a sturdy and long-lasting product. without welding points for no corrosion troubles high precision manufacturing process for high quality product Real forward curved impeller The impeller has been optimized for the best efficiency, match to the special motor features. We manufacture the high performance impellers through a highly automated and innovative production process. low noise level low power consumption Optimized external rotor motor The fan impeller is directly mounted on the motor thus providing efficient motor cooling by the fan airflow. Motor speed can be adjusted either by the use of transformers and TRC regulators. Motors are generally fitted with thermal protector for against overheating. high reliability and efficiency wide range of operative conditions Vibration isolation The vibration isolation pads of the motor shaft ensures a very low noise during fan operation and no transmission of noise and vibrations to the other parts of the fan, making installation more quiet and comfortable. low noise level no noise and vibrations transmitted to the surrounding structures Easy electrical connection ll fans could be provided with connection box, terminal block or loose cable. wiring diagram sticker, placed on each fan, describes the correct electrical connection. fast and easy wiring safe operation 4
