Variable Frequency Drives

Variable Frequency Drives (VFD)

Increased operational life and reduced maintenance and repairs

Variable Frequency Drives (VFD)

The trend within industry to use VFD stemmed from the need to reduce operating costs by optimizing energy consumption and improving flexibility for their users. They incorporate specific motor control features, such as energy savings ratio which can be reduced by up to 50% when compared to traditional solutions. Introducing energy efficient VFDs can result in receiving LEED credits from the USGBC. On most models at any given time, the consumption of the drive is displayed on a readout panel. All our VFD systems conform to safety standards and codes.

The benefits of variable frequency drives

Unlike their fixed speed predecessors, VFDs are adjustable to control motor speeds, torque, and energy usage. This results in marked improvement for fan, compressor, and pump industrial uses such as temperature, pressure, flow, and acceleration. Reducing the stress on devices like AC motors greatly increases their operational life and reduces maintenance and repairs.
