Fan efficiencies RLM – RZR - RQM +15% !
Benchmark Up to 78 % system efficiency • • The RQM Multi. Evo reaches approx. 15 % higher energy efficiency than the best freerunning 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 Multi. Evo are up to 4 d. B lower.
