Variable Speed Drives

Cochran supply, install, and commission all major makes of drive invertor.

Using Varible Speed Drives can offer electrical savings in excess of 50% if running on part load. They also overcome other problems experienced with fixed speed motors such as star/delta transients and shock loads, which decrease component life.

Linked to a suitable boiler controller, Variable Speed Drives offer refined combustion control. Cochran offers complete control and motor packages with the option of motor control from the boiler controller itself or via an oxygen trim package.

These packages are particularly suited to boilers that run on low to mid fire or have to provide a fluctuating load throughout the day.
