Variable speed drive grant

Variable speed drives (VSD) are one of the most cost effective energy saving technologies you can install across a range of commerical applications.

What is a variable speed drive?

A Variable Speed Drive (VSD) is like a ‘dimmer switch’ that automatically reduces the speed of a motor when it is not busy. You may have noticed this effect on escalators which slow down when no one is on them and speed up when in use. A VSD can dramatically reduce the amount of electricity used by motors used for intermittent jobs e.g. pumps, ventilation fans, air compressors, refrigeration etc.
