SHR 3205RD
Heat Recovery Ventilator
Suitable for very large residential or small commercial applications, the compact
SHR 3205RD comes with access panels on both sides of the unit for installation
versatility. The unit is designed for higher static pressure and higher airflow
applications. The unit brings a continuous supply of fresh air into a home while
exhausting an equal amount of contaminated air. During winter, fresh incoming
air is tempered by the heat that is transferred from the outgoing air so you save
on energy costs, while during summer, the incoming air is pre-cooled if the
house is equipped with an air cooling system.
During the def rost sequence, a motorized damper temporarily blocks the incoming
fresh air stream so that the warm air from the house 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. During this cycle,
household odors from the kitchen or bathroom are prevented from entering the
home and the unit will not create negative pressure.
Airflow up to 267 cfm @ 0.4” Ps serves up 7 bedroom homes
Access doors on two sides of the cabinet for multiple
