NexRev DrivePak
http://www.nexrev.com/products/drivepak/
DrivePak by NexRev LLC is a proven, cost-effective variable frequency drive (VFD) upgrade for existing packaged rooftop HVAC equipment. DrivePak greatly reduces the cost of operating rooftop units (RTUs) while optimizing occupant comfort by reducing the speed of the blower fan to the actual heating or cooling load as indicated by the “calls” sent by a thermostat or EMS system. Local utilities are subsidizing the installations through their rebate programs.
