Variable Frequency Drives

VFDs drive powerful savings


Control motors in equipment, pumps and fans for savings up to 40%


Every motor is a candidate for a VFD

Variable frequency drives (VFD) can deliver the biggest savings when applied to motors and pumps in industrial equipment, fans, HVAC and water systems.

Currently, many motors are “always on”, running full out only to be throttled by dampers and valves. This wastes energy and puts extra strain on the motor. VFDs can control and adjust the speed and torque of motors as demands change. That means you save energy and cut costs.

Managers of commercial or residential high-rise buildings should evaluate their water systems for the application of VFDs. Often, even newer buildings can benefit.

On farms, look at motorized equipment such as conveyors and ventilation fans for savings opportunities.


Savings and daily benefits

Cut costs between 10% and 40%


The savings delivered by VFDs will depend on the size of the motor and hours of operation. However, savings between 10% and 40% are typical, and paybacks can be a matter of months.

Benefits of VFDs beyond savings


VFDs reduce the wear and tear on your motors, which means longer life and reduced maintenance time and costs. Depending on the number of motors, this can be a substantial secondary saving.

Installation can be accomplished in a day for minimal down time.

An audit will identify opportunities


Pumps and motors can be “hidden” deep in equipment and pumping systems. That’s where an audit can be useful to uncover and prioritize your potential savings.

Audits can also identify motors that should be replaced with more energy-efficient alternatives. Audits also qualify for incentives up to 50% of the cost of the audit, up to $25,000.

Premium efficiency motors bring premium benefits


Premium efficiency motors are typically 4% more efficient than standard motors. They’re also higher quality, more reliable and give off less heat. There are two types:

  • Open Drip Proof (ODP) motors are well suited to cleaner applications where dust and dirt won’t contaminate them.
  • Totally Enclosed Fan-Cooled motors (TEFC) are better for spaces with dust or corrosive material.
