Best solution for a wide range of applications.

Refrigeration, ventilation, air conditioning and mechanical engineering are accompanied by tough ambient conditions. If you want to cope with them effectively, you need electrically and mechanically robust solutions that also work at a high level of efficiency. 

Durable, highly efficient and quiet.

Over the entire product series, the AxiEco Protect makes a great impression with its robustness, high performance, low noise levels and economical operation both in its EC and AC design.

Clever design details for perfect protection.

In accordance with the latest findings in aerodynamics, the blade shape has undergone three-dimensional improvements and the impeller has been optimized.

The fan guard grill is made of metal, making it very robust.

In the AxiEco Protect, there is no longer any tip gap between the fan housing and the impeller. The impeller, integrated diffusor ring and hub form a compact unit and the blade tips seamlessly join the oil slinger. This brings two advantages: Firstly, there is no flow over the blade tips. This increases efficiency and reduces noise. Secondly, the blades can no longer freeze on the nozzle.

The fan blades of the AxiEco Protect have grooves. This increases its mechanical stability, in turn enabling a higher power density

false

The integrated diffusor ring of the AxiEco Protect also performs the function of a diffuser. This means that it is integrated directly into the impeller, which has a larger outflow angle than other axial fans. As it makes the pressure increase, the diffuser reduces outlet losses, meaning that it contributes to noise reduction.

Questions and answers about the AxiEco Protect.

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 many more 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: The AxiEco Protect has no tip gap, therefore it is unlikely that the impeller freezes up. Last but not least, its better flow profile delays the formation of ice on the guard grill, because the interior air is not drawn in again but remains in an axial direction.
Since the AxiEco Protect 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 overall efficiency, but also saves space.
More stringent demands will be placed on the efficiency of fans by the time the next stage of the ErP comes into force. The AxiEco Protect already easily fulfills these criteria: its efficiency ratings are impressive. It boasts an efficiency increase of over 20% compared to the HyBlade with full nozzle (depending on the size).
The AxiEco Protect is up to 6 dB(A) quieter than the HyBlade (depending on the size). The main reason behind this is that the impeller, integrated diffusor ring and hub of the AxiEco Protect form a compact unit. The blade tips seamlessly join the integrated diffusor 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.
In the next stage of the ErP Directive (Energy-related products directive), the EU is stipulating mandatory minimum efficiency levels for fans. A device will only be able to bear the CE label if it fulfills the required standard values. With the AxiEco Protect, manufacturers are on the safe side and are ideally equipped for the future. The AxiEco Protect fully complies with the new ErP requirements. Its efficiency is considerably better than that of previous axial fans, meaning that it operates much more efficiently.
The new AxiEco Protect meets the requirements of the next stage of the ErP regardless of the motor technology used, but EC technology offers additional benefits:
– better efficiency than AC motors
– less waste heat and, therefore, lower energy consumption
– demand-based control via a 0 to 10 V signal
– some motor variants can also be controlled via MODBUS-RTU
