Heat recovery ventilation

Heat Recovery Ventilation

A heat recovery ventilation system modulates the temperature and humidity of incoming fresh air to match indoor conditions.

A balance is therefore achieved between indoor and outdoor ambients, enabling the cooling or heating load placed on the air conditioning system to be reduced significantly.

HRV units can be controlled individually or integral with air conditioning system.
