SHR 6905R
Commercial Heat Recovery Ventilators
The SHR 6905R Commercial Heat Recovery Ventilation system (HRV)
complements today's tight buildings. Fantech Heat Recovery Ventilators (HRV)
are designed to supply air into a building while exhausting an equal amount of
contaminated air to the outside. The aluminum heat exchange core transfers
sensible energy between air steams resulting in tempering of the supply air and
reduced loads on the HVAC system.
During the defrost sequence, a motorized damper temporarily blocks the
incoming fresh air stream so that the warm air from the building can circulate
through the HRV. The exhaust blower shuts down and the supply blower
switches into high speed to maximize the effectiveness of the defrost strategy.
