Nicotra Gebhardt’s new compact fan delivers unrivalled energy efficiency.
The RQM ‘MultiEvo’ beats traditional plug fans on energy efficiency* thanks to the optimisation of key components, including a hollow section ‘aero-foil’ backward curve impeller, a permanent magnet (PM) internal rotor motor rated at IE5 efficiency and integrated electronic controls.
The compact RQM can be fitted at multiple access points for ease of maintenance and is ideal for ‘new build’ and refurbishment/retrofit.
The company’s ‘MultiEvo’ technology has delivered a range of directly driven hybrid centrifugal fans with multiple discharge outlets and static system efficiencies of up to 78%. The multispiral technology combines the compact design of plug fans with the effectiveness/reliability of traditionally ‘housed’ fans that offer static pressure increase and energy efficiency.
Depending on fan size, the RQM reaches 8 to 15% higher energy efficiencies than ‘best on market’ traditional plug fans The RQM range includes all standard fan diameters from 355mm to 710mm, providing performances of up to approximately 6.5m3/s (23,000m3/h) and/or total pressures of up to 1750Pa. The PM motors are, as standard, IE5 rated and available with motor powers up to 6.5kW (free of rare earth materials) together with integrated electronics.
