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.
