Heat recovery ventilation unit for through the wall installation which exhausts stale air whilst introducing warmed fresh air from the outside. As a heat recovery ventilation unit it moves a useful 153 l/s of air. This unit is fully speed controllable with the facility to reverse the supply air fan and provide 'double extraction' for periods when heat loss is desirable.
The unit is the perfect solution to commercial areas that require a high performance balanced intake/extract scheme. Ideal for swimming pools, computer rooms, classrooms, offices and the health and leisure industries. In noise sensitive areas use an auto transformer controller.
The unit should be ducted to atmosphere using an integral wall liner and should fit wall thicknesses between 450 and 670mm and should have washable reticulated foam filters provided in the supply and extract airflows.

Efficiency: The unit should retain up to 70% of the temperature differential of out going air.
Heat exchanger: Should be of a multi plate cross-flow type constructed out of a polymeric plastic with ultra sonic welded joints.
Motor: Should be a 240V 50Hz A/C with sleeve bearings, greased for life. It shall operate up to an ambient temperature of 40°C and be fitted with a manual reset thermal overload protective device.The supply motor shall be configured to be reversible thus providing an extract only option.
Fan: The 2-N° polymeric fan impellers should be of a mixed flow type, dynamically balanced mounted on a fixed stator housing.
Controls: The unit should be operated via a dedicated remote infinite variable speed and reverse switch with sensor option to allow for humidistat or PIR input.
Back Draught Shutter: The unit should have the option back draught shutter operated via a thermal actuator set to close when unit is powered down.
Filter: Should be a washable reticulated foam type coarse filter.
Construction: The unit outer case should be a rigid HIPs moulding configured so as to make the unit telescopic. The internal/external grille should be a cream coloured ABS moulding.
