ComfortDisc can be used as a stand alone heat recovery. Its modular construction makes installation in tight spaces easy. The large capacity supply and exhaust fan motors are designed for multiple extract points and air volumes of up to 750 M3/Hr at 300pa.  This makes the ComfortDisc HRV ideally suited to large homes and commercial spaces where large amounts of supply and extract duct may be required.

The controller can be configured to supply a fixed amount of extract air and fresh air or can use a carbon dioxide CO₂ sensor to vary the ventilation rate as the occupancy levels increase or decrease. This gives exceptional energy efficiency in buildings with variable occupancy.
