Variable Frequency Drives

At Mechanical Air Concepts we trust Danfoss Variable frequency drives.  Please contact us if you need pricing or startup of Danfoss Variable frequency drives.

Save Big with Installation of Variable Frequency Drives!
While constantly expected to do more with less, managing energy consumption and optimizing occupant comfort remains of utmost importance to facility managers. Products that integrate seamlessly into existing equipment and building management systems are also essential. Sander Mechanical’s variable frequency drive (VFD) portfolio can deliver all of this and more.
What are Variable Frequency Drives or VFDs?
A variable frequency drive (also termed variable-speed drive, adjustable-frequency drive, adjustable-speed drive, AC drive, micro drive, or inverter drive) is a type of electric motor controller used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage. Motors are usually sized for maximum demand volume, but typically need to operate at this level only a small percentage of the total operating time. For this reason, VFDs are an incredibly effective tool for achieving energy savings by reducing motor speed, volume, and power usage to match actual load requirements.


VFDs can be utilized effectively on a variety of equipment:

  • Air Handling Units
  • Return & Supply Fans
  • Exhaust Fans
  • Centrifugal Pumps
  • Domestic Water Booster Pumps
  • Cooling Tower Fans
  • Condenser Water Pumps
  • Centrifugal Chillers
  • Primary / Secondary Chilled Water
  • Boiler Feed Pumps
For example, cutting fan speed in half with a VFD lowers the required horsepower by a factor of eight, as fan power is proportional to the cube of fan speed. So depending on motor size, the energy savings (combined with energy efficiency incentives and utility rebates) can often payback VFD installations in less than one year.

Benefits of using Variable Frequency Drives VFDs
Reduce Energy Consumption and Operating CostsVariable Frequency Drives allow for the precise matching of the speed of motor-driven equipment to the load requirement, thereby reducing energy consumption by as much as 50%. There is no other method of AC electric motor control that allows you to accomplish this.
