Process VFDs
A Variable Frequency Drive (VFD) controls the speed and torque of electric motors and is used in a wide range of industrial processes to optimize energy efficiency and improve process control.
Motors can use more energy than any other piece of equipment in a building — supplying ventilation, running pumps, and heating and cooling your space. But many motors run at a constant speed even at times of low demand — wasting energy and wearing out your equipment more quickly.
Variable frequency drives (VFDs) operate at lower speeds during periods of lower demand to help your pump and fan motors operate more efficiently and reduce wasted energy.
Financial Incentives for Process VFDs
Financial incentives to install VFDs on existing pump or fan motors could cover up to 80% of your total project cost. Individual motors over 500 hp may be eligible as a Custom project.
VFDs are versatile and can be used in a variety of ways, including:
- Air-cooled chillers
- Gas furnaces
- Gas air heaters
- Gas boilers and boiler controls
- VFD on HVAC motors
- High Temperature High Volume (HTHV) direct fired heaters
- Demand-controlled ventilation
- Advanced rooftop controls
- Commercial water heaters
- HVAC tune-ups
