Efficient Motor Control for HVAC Systems
Variable speed drives such as the Danfoss 131G9661 regulate motor speed by adjusting the frequency and voltage supplied to the motor. This allows HVAC equipment to operate according to real system demand rather than running continuously at full speed, helping to reduce energy consumption, noise and mechanical wear.
The VLT® HVAC Drive FC 102 series is developed for ventilation, heating, cooling and refrigeration applications. Its dedicated HVAC control functions make it well suited for fans, pumps, compressors, air handling units and building management systems where efficiency and reliable operation are essential.
Typical Applications
- HVAC systems and building automation.
- Air handling units and ventilation systems.
- Supply and extract fans.
- Heating and chilled water pumps.
- Cooling towers and refrigeration equipment.
- Compressors and process cooling systems.
- Commercial buildings, industrial facilities and plant rooms.
