Trane DRV3113 1.5HP Variable Speed Drive 208V TR170

The Trane DRV3113 is a variable speed drive that enhances performance an functionality of HVAC systems. Unlike on/off switches, a VSD fine tunes the speed of the attached motor, which in the case of the Trane TR170 air handler unit is a blower fan. This enables constant control of the flow of air as a result of the cooling or heating needs at any one time. It uses less energy than systems with fixed speed blowers. Also, it reduces temperature swings, making for more steady comfort in your area of living or working. In addition, the fact that the motor operates at variable speed means that your HVAC system will run more quietly.
