Modern heating calls for new concepts based on renewable energy instead of fossil fuel. This is why heat pumps are enjoying increased popularity. The size 500 axial fans from ebm-papst were specially engineered for use in outdoor heat pumps and now they have been optimized for energy efficiency and noise reduction. The ready-to-connect plug and play unit consists of the new,
patented fan housing system with an integrated diffuser, motor, electronics, and HyBlade impeller - all perfectly harmonized. With its pressure-raising effect, the diffuser integrated in the fan housing lowers outlet losses significantly, allowing an air performance increase of up to 10% while reducing noise by up to 3 dB(A). For the entire fan system, this adds up to 23% more efficiency than conventional solutions - the best prerequisite for a high coefficient of performance (COP) value for the entire heat pump.
