Greentek RD-4P Professional Dehumidistat (4-Wire) for air exchangers
An Air Exchanger otherwise known as an HRV (Heat Recovery Ventilator) or an ERV (Energy Recovery Ventilator), is a whole house mechanical ventilation system. It is typically connected to your existing furnace return duct and contains two high-efficiency motors. The supply motor draws fresh air in from the outside while the exhaust motor pushes stale indoor contaminated air outside. The two airstreams never mix when passing through the HRV or ERV cores.
Benefits of Air Exchangers:
Air Exchangers bring a continuous supply of fresh outside air into your
Air Exchangers exhaust environmental contaminants for improved indoor air quality.
Air Exchangers save energy in the winter by recovering heat from exhaust air.
Air Exchangers save energy in the summer by recovering cool indoor air from exhaust air.
Air Exchangers help prevent mould and mildew.
Air Exchangers help minimize odours and cooking residue.
Air Exchangers can reduce harmful Radon Gas levels where active soil depressurization is unlikely to be successful.
