Variable Speed Drives

Vesta Group’s preferred products are the Danfoss VLT range, specifically designed for HVAC applications.

Variable speed drives (VSDs) are designed to vary the speed of a normally fixed speed motor. In HVAC applications, they are used primarily to control fans and pumps. If your Cooling Tower fan is not required to run at constant full speed or full time, introducing a VSD to control these requirements, can increase the efficiency of the unit and drastically reduce your energy costs.
