Blauberg UK Komfort SB-550 MVHR Heat Recovery Unit with S11 Controls

DESIGN: The casing is made of double-skinned polymer coated steel panels, internally filled with 20 mm mineral wool layer for heat- and sound-insulation. The hinged panel of the casing ensures easy access to the internals for cleaning and other maintenance operations. The spigots for connection to the air ducts are located at the top of the unit and are rubber sealed for airtight connection to the air ducts. FANS High-efficient external rotor EC-motors and centrifugal impellers HEAT RECOVERY The unit is equipped with a plate counter-flow polystyrene heat exchanger with a large surface area and high heat recovery efficiency. Heat recovery is based on utilization of heat energy contained in the extract air stream for heating up the supply air stream. Extract air transfers most of its heat to the intake air flow. Heat recovery reduces heat energy losses in cold seasons. In summer the heat exchanger performs reverse and transfers a part of the accumulated coolness from the cooled extract air for warming up the intake air. This contributes to better performance of air conditioners in ventilated premises. The drain pan under the heat exchanger block is used for condensate collection and drainage. The drain pan is fitted with a drain pipe for condensate removal. The electronic freeze protection system is used to prevent the heat exchanger freezing in cold seasons. In case of a freezing danger registered by the temperature sensor the supply fan turns off to let the heat exchanger surface get warmed up with warm extract air flow. After a freezing danger is over the supply fan in turned on and the unit reverts to the standard operation mode. BYPASS Equipped with the 100% bypass for summer ventilation (room cooling by the cool intake air). S11 automation functions: Bypass damper opening / closing for summer ventilation. Setting and maintaining room or duct air temperature. Timer turning on/off and timer operation adjustment. and many more.
