Fans in evaporators have to overcome high counter-pressure since the ice that often forms on the heat exchanger constricts the air channels. AC axial fans in particular, which are in widespread use, will reach their limits at the very latest when the next stage of the ErP Directive goes into effect.
That is why ebm‑papst has developed the AxiEco axial fans, which have successfully established themselves on the market for two years. These fans also offer exceptional pressure stability with high efficiency. Its air performance curve has a much steeper slope than comparable axial fans. Aerodynamic optimization of the impeller achieves a better and even airflow, and the noise level has been significantly reduced again. When used in evaporators, for example, the service life is also extended, i.e. the intervals between defrosting cycles. This also saves energy and increases the device’s overall efficiency.
Higher air flow rates and pressures thanks to new sizes
The existing AxiEco EC fan series, with sizes 300, 350, 400, 450 and 500 mm, has now been expanded with the three new larger sizes 630, 800 and 910 mm, meaning that even higher air flows of over 25,000 m³/h and pressures of up to 700 Pa can be achieved. All AxiEco fans meet the requirements of the future ErP Directive and can be easily integrated into applications as a compact plug & play solution with CE marking. Users will not have to worry about nozzles or distance to the impeller, nor concern themselves with conducting their own ErP assessment. These new sizes cover other areas of application in ventilation, air conditioning and refrigeration technology, such as use in chillers and evaporators, industrial process refrigeration, data centers and mobile refrigeration technology (rented refrigeration).
