VFDs and Electrical

Better control while saving energy. VFDs do that for you.

Honeywell Process Solutions

Honeywell variable frequency drives (VFDs) maximize energy savings by modulating the speed of fans and pumps in HVAC systems. VFDs, sometimes called inverters, achieve these savings by operating in conjunction with a building automation system (BAS) or independently through its internal PID capabilities. Honeywell VFDs  are loaded with labor-saving features such as startup wizards, PC programming, and an intuitive graphical interface that allows for faster, more accurate commissioning.
