One concern of controlling a ventilation system is poor air quality. The programmable minimum frequency can be set to maintain a minimum amount of supply air regardless of the feedback or reference signal.

Several features of the Danfoss HVAC dedicated frequency converter, the HVAC frequency converter can be utilised to improve the performance of a cooling tower fans application. As the cooling tower fans drop below a certain speed, the effect the fan has on cooling the water becomes small.
