Variable Frequency Drives

The world is moving towards electronic controls as the standard for controlling electric motors. AC drives improve the ability to control speed, accuracy, product quality, energy efficiency, and motor protection. We are a leader in the field of AC Variable Frequency Drives. We provide installation, programming, and service on the AC drives we sell.

Variable frequency drives (VFD) are reliable electronic devices that control three-phase electric motor speed. They are used in building automation, industrial, pumping, agricultural, irrigation, and water/wastewater applications to control the speed of fans and pumps in various systems. 


Drives do more than reduce energy cost:

  • Drives reduce fan noise and duct rumble.
  • Drives reduce amps during motor starting, lowering demand charges; another significant part of the electric bill.
  • Drives are less expensive to maintain than mechanical controls.
  • Drives inherent soft-starting reduces wear and tear on motors, sheaves, belts, couplings and other system components.
  • Drives provide accurate and repeatable control of HVAC settings, eliminating frequent readjustments.
  • Drives offer greater motor and application protection.
