Variable Frequency Drives
Variable frequency drives (VFDs) save energy and reduce equipment wear and tear by modulating the speed of fans and pumps in HVAC systems.
Honeywell Building Technologies
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. A Honeywell VFD is loaded with labor-saving features, such as startup wizards, PC programming, and an intuitive graphical interface that allows for faster, more accurate commissioning.
