FanTech SH 704 HRV
Compact HRV with easy-mount, wall bracket. Brings a continuous supply of fresh air into a home while exhausting an equal amount of contaminated air. HRVs use what is called a “sensible” heat recovery core. This special core transfers heat from the exhaust air stream to the incoming air stream. Fresh incoming air is tempered by the heat that is transferred from the outgoing air to save on energy costs. The SH 704 is equipped with automatic defrost mechanisms so even if you live in the coldest climates you can use your HRV all year long.

Defrost:
The automatic defrost cycle consists of a fan shutdown. When the supply air stream temperature goes below 23°F, the supply motor shuts down while the exhaust motor continues to ventilate. Ambient air is passed through the unit for a period of 3 or 5 mintes. The supply motor will then restart and run at the present speed. This fan shutdown defrost cycle contunes until the supply air stream rises above 23°F.
