The AxiEco Protect fan with guard grill is particularly well-suited to noise-sensitive applications, as its noise emissions are very low. By contrast, the AxiEco Perform fan with housing is recommended in situations that require a ready-to-install fan. With air flows over 12,000 m³/h and pressures of up to nearly 500 Pa, its range of applications is very wide, from heat pumps and evaporators to industrial ventilation systems and cooling air compressors. The AxiEco Perform can be used to draw air in or push it out.

Ice formation particularly afflicts evaporators if the humidity precipitates on the heat exchanger as ice at cold ambient temperatures. This means that the air path is restricted and the pressure increases. This is where the AxiEco Protect’s key benefit comes in: At higher back pressures, it offers much greater pressure reserves than other fans. This extends the intervals between defrosting cycles and means that the refrigerating plant can be operated more efficiently for longer periods. Another advantage is its optimized ice formation behavior: AxiEco axial fans have no tip gap. meaning that the impeller is unlikely to freeze up. Last but not least, its better flow profile delays ice formation on the guard grill because the interior air is not drawn in again but remains in an axial direction.

Since the AxiEco series can be operated at higher speeds, it achieves a higher air performance per area. Compared to other axial fans, this means that fewer fans are required to deliver the same performance. This not only increases the overall efficiency, but also saves space.

There will be more stringent requirements for the efficiency of fans by the time the next stage of the ErP comes into force. The AxiEco series already easily fulfills these criteria: in terms of performance, the AxiEco Perform impresses compared to the HyBlade; with its full nozzle, it is much more efficient.

The AxiEco series is up to 6 dB(A) quieter than the HyBlade (depending on the size). The main reason for this is that the impeller, integrated diffuser ring and hub form a compact unit. The blade tips seamlessly join the integrated diffuser ring so there is no longer any tip gap between the fan housing and the impeller. This results in hardly any turbulence in the edge area – and therefore also less noise. The integrated diffuser also helps to reduce noise, meaning that the noise level remains pleasantly low even at higher pressure ranges.

With the next stage of the ErP Directive (Energy-related Products Directive), the EU has set out binding minimum efficiency levels for fans. Only those who meet the required standard values will receive the CE mark for their end devices. With the AxiEco series, manufacturers are on the safe side and are ideally equipped for the future. The AxiEco series fully complies with the new ErP requirements. These fans are considerably more efficient than previous axial fans, meaning that they operate much more efficiently.
