Variable Frequency Drives


Yaskawa is the largest global variable frequency drives manufacturer with over 30 years of Building Automation System (BAS) and HVACR experience. Our variable frequency drives are designed for HVACR applications, which include air handlers, cooling towers and pumps, by combining reduced size and cost with step changes in performance and quality. The drive features for Building Automation Systems include extensive parameter selection which simplifies management of BAS applications for energy efficiency and closed loop control, industry-standard Hand/Off/Auto functionality, an internal PI controller and a Sleep function. Because all variable frequency drives (VFDs) are rigorously tested, Yaskawa ensures that quality and reliability are designed and built in.

E7 Drives have embedded Metasys® and APOGEE™ Communications. BACnet® and LonWorks® are optional.
