HR200WK
Overview
A heat recovery unit specifically designed for use in residential kitchens and utility rooms to meet the latest building regulations. The compact, self contained unit is designed for through wall mounting. The unit has a constant trickle ventilation boosted by a remote humidistat or a 3 speed controller. The compact, self contained unit is designed for through the wall mounting. An optional range of sensors are available.
The efficient, polymeric heat exchanger cube will recover up to 75% of the heat from the extracted air, which would otherwise be lost, and transfers this to the intake air.This reduces heating bills whilst maintaining extraction of cooking odours and steam without cross contamination of the airflows. Available in three speeds: 60, 110 and 220m³/h. Suitable for installation in a kitchen.
The unit is also suitable for light commercial requirements up to 220m³/h.
Heat Exchanger
The compact cube interleaves outgoing moist warm air with incoming fresh air and allows the heat from one to warm the other without the two air streams mixing. Up to 75% of the heat, which would otherwise be lost, is transferred to the intake air, ensuring energy saving balanced ventilation.
The incoming air is tempered when it passes over the heat exchanger providing the room with drier air, therefore the humidity level drops due to the constant air movement preventing the air inside the room from becoming saturated with moisture. Energy is saved on room heating with no power being used by the cube itself.
Typical Installation
The HR200WK fits through walls up to 335mm thick requiring a fixing hole 250mm square. The internal grille has washable, polymeric foam supply and extract filters. Only the neat internal twin grille visible from the room.
A wall extension sleeve is available.
Maintenance
Apart from removing odours, providing fresh air and recovering heat, this appliance extracts airborne impurities such as dust, dirt and grease. These gradually build up and detract from the efficiency and appearance of the appliance. Therefore to ensure peak performance, the appliance should be cleaned regularly. Filters should be replaced every six months or as conditions necessitate. Quick release grilles give instant access to the integral washable filters. The heat exchanger and grille should be washed in warm soapy water every twelve months or as conditions necessitate.
