Heat-recovery units

Model PVe heat-recovery units are designed to recover up to 60 percent of the sensible energy in exhaust air and return it to supply air. The cross-flow plate-exchanger units use an aluminum core to recover only sensible energy, with low leakage and no moving parts. Features include stainless-steel drain pans, belt-drive blowers with adjustable pulleys, a pitched roof, and integral lifting points and lift locations. Useful for applications that involve dirtier air, such as garages, welding shops/facilities, and areas with drier climates, the units' performance ranges from 1,000 to 6,000 cfm. Visit for more information.
