  1. R&D Nicotra Gebhardt GmbH released: Dr. Johannes Anschütz, 19.05.2017

  2. FDP new Centrifugal, directdrivenfanwith scroll casing, forwardcurvedimpeller, aluminium Fan Deck application Double inlet internal rotorbrushlessDC („EC“) motor, max. 1 kW ErP 2015 andpresumably 2020 compliant Fans for Ventilation and Air conditioning

  3. New P2M+/P3 new • Significant price step from P2 to P4 Fan solutions for industrial and process applications P3 P2 P4

  4. Fan solutions for industrial and process applications

  5. P3 standardisation

  6. The challenge ? Plug fans Centrifugalfanswithhousing Possibilities for improvement are exhausted. New fan concept maximum efficiency

  7. The challenge ? Plug fans Centrifugalfanswithhousing Possibilities for improvement are exhausted. New fan concept maximum efficiency

  8. Fan efficiencies RLM – RZR - RQM +15% !

  9. Benchmark Up to 78 % system efficiency The RQM MultiEvo reaches approx. 15 % higher energy efficiency than the best free-running or traditional fans with EC technology on the market. The measured absolute system efficiency levels reach values of up to 78% depending on the size. (system = fan, motor, frequency converter). And: Depending on the duty point, the noise emissions of the RQM MultiEvo are up to 4 dB lower.

  10. Erreichbarer Wirkungsgrad Statischer Systemwirkungsgrad Ventilator, Motor, Frequenzumrichter 78% RQM Bis 68%, mit PM motor Bis 64%, Evo Laufrad (Schaufeln profiliert), EC motor 60%, rückwärts gekrümmt, Schaufeln unprofiliert, EC- Motor

  11. Vergleich RQM MultiEvo - RLM

  12. RQM Typenübersicht mit PM-Motoren und integr. Elektronik

  13. RQM MultiEvo Kennfeld mit PM Motor Maximale Drehzahl Baugrößen bei stat. Ventilatorwirkungsgrad über 80 %

  14. RQM MultiEvo – Installation conditions Empfehlung: A/D2 1.8 Recommendation: diamaeter of chamber/impeller size  1.8 D2  0.1*D2 A 1.6*D2

  15. RQM installation losses Installation losses = 100 % 1,6 * D2 Installation losses = 0 % 2,2 * D2

  16. RQM installation conditions • Up to 78 % system efficiency • Easy installation on the floor, wall or ceiling • Simple component replacement while servicing and maintenance • Easy accessibility, for example, in case of cleaning

  17. Vergleich Schallwerte RLM vs. RQM -1…-4db

  18. RQM MultiEvo – Multiple wall configurations

  19. RQM Standard Evo impeller without diffusor in „multi“ housing Size range from 280 to 900; direct drive Possible extension up to size 900 and bigger PM motors (Domel) Versions with integrated controller (OJ) Basic version for wall mounting, bigger sizes with feet up to size 630 mm but generally suitable for all installation positions Standard temperature range -20 to 40°C Ready for future updates of ErP regulation 327/2011

  20. Anwendungsbeispiele RQM Anwendungsbeispiele Server cooling Control cabinets Generator cooling Replacement for RLM and RLE applications
