How DrivePak Delivers...
NexRev's DrivePak family of products reduce the speed of HVAC equipment blower fans, to match the actual heating and cooling loads, as indicated by the "calls" for heating and cooling from the existing temperature control device or system.
DrivePak delivers significant savings primarily due to the Fan Affinity Law (Physics), which states the power used by a fan motor is reduced exponentially as the speed is reduced.
- 20% Reduction in Fan Speed = 47% Reduction in Power
- 50% Reduction in Fan Speed = 87% Reduction in Power
Matching the fan speed to the actual load needs creates exponential power reduction benefits and dramatic energy savings. The DrivePak line of solutions is designed to meet various applications and needs of customers, as well as many utility incentive programs.
