What are VSDs, and how do they work?

Variable speed drives – also known as adjustable speed drives (ASDs) or variable frequency drives (VFDs) – control the speed and torque of motors that drive fans, pumps or compressors in HVAC systems.

VSDs can dramatically reduce energy use while prolonging the lifespan of your heating and cooling equipment. They work by adjusting the frequency (Hz), voltage (V) or current of your existing HVAC system to better meet load requirements.

Benefits of VSDs

  • Save approximately 35-50% on energy.*

  • Reduce power consumption.

  •  Lower operating costs.

  • Minimize wear and tear on fans, pumps and compressors.

  • Extend HVAC motor life.

  • Protect equipment from power fluctuations.

  • Limit and adjust the amount of torque delivered to HVAC motors.

  • Prolong the lifespan of your HVAC equipment.
