It is the standard way to ventilate offices, schools, gyms and clinics efficiently.

What the work involves
Units use plate exchangers (no mixing of air streams) or rotary wheels (higher efficiency, small transfer of moisture). The right choice depends on the use: a gym or swimming area has very different moisture loads to an office. We size units to the building's occupancy and fresh-air needs, plan the duct connections and controls, and commission the system so the design airflows are actually achieved.
Floor or roof units
Larger units for schools, gyms and halls.
Demand control
CO2-led control for variable occupancy.
Replacement of old ventilation
Extract-only systems upgraded to balanced heat recovery.
