SHR 6904
Commercial Heat Recovery Ventilators
The SHR 6904 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.
A preset defrost sequence is activated at an outdoor air temperature of 23ºF
and lower. During the defrost sequence, the supply blower shuts down & the
exhaust blower continues to ventilate for a few minutes. The unit then returns
to normal operation, and continues cycle.
