Demand-Controlled Fans

Demand-Controlled Fans (infographic)

In ventilation plants, G120P variable speed drives help you cut costs and optimize safety. The drives ensure that supply and exhaust fans are operating according to actual demand.

More safety and efficiency

As standard, the G120P can detect a variety of events, such as when:

  • Belt has failed

  • Fan is blocked

  • Motor is overloaded

  • Bearing is worn down

The G120P continuously monitors key parameters such as power consumption and speed and alerts the user if the airflow is interrupted. An external belt monitor is not required. Whenever demand is low, the intelligent hibernation mode kicks in, reducing energy consumption and wear. Last but not least, the G120P also has an automatic restart function in case a short disturbance or power outage should occur.
