Variable Frequency Drives (VFDs)

Reltech Drives and Controls specializes in the sales, installation, commissioning, preventative maintenance, and servicing of Variable Frequency Drives (VFDs). These are sometimes also known as soft starts, inverters, or variable speed drives (VSDs). A VFD is an Adjustable Speed Drive (ASDs) used in electro-mechanical drive systems to control Alternating Current motor speed and torque by varying motor input frequency and voltage.

It is estimated that 18% of the energy used in electric motors could be saved by efficient energy improvement technologies such as VFDs. The net payback in energy savings that can be achieved in many applications is substantial.

VFD’s have numerous applications, including pumps, fans, make up air units, chillers, motors, ventilation systems, industrial drive systems and more.
