Often large companies doubt energy saving investments and question the speed of their ROI. According to Control Engineering Magazine, the following areas are the most effective in providing the largest savings in terms of cost and energy.

• Power management

• High efficiency motors

• Variable speed drives

Variable frequency drives (also known as an inverter or a VSD) are the most straightforward forms of energy saving technology a company can invest in. But just how efficient are they? You may be surprised at the savings you can make with variable speed drives.

Save Up to 50% on Energy Use with a VSD

Did you know most fans and pumps are over-sized for the duties they perform? According to the Carbon Trust, using a VSD to slow down a fan or pump motor from 100 to 80% can save as much as 50% on energy use. Reducing fan speeds not only provides vital savings on energy but can also lessen noise and vibration. Other assets that can make use of these drives include mixers, centrifuges, reciprocating compressors and extruders.

According to figures by the Carbon Trust, a VSD can have a payback period of less than two years – making variable speed drives the ideal investment.
