Our tests show that current VFDs designs are not operating at the high efficiency levels that manufacturers claim as, in the real-life operational conditions of varying speeds, the efficiency varies significantly -- dropping well below the 97% efficiency, which is widely claimed, to as bad as 60% or even less!

Naturally, not all VFDs are created equal and vary in quality and price but, in every test comparison, our next generation QPT VFD provided significant energy savings. Which also means less energy is wasted in the form of heat so less or no cooling is required.

The proof point for our mission to reduce climate change by reducing energy wastage.
