VX,VR – Heat recovery units www.systemair.com Good ventilation for private houses, daycare centres, smaller offices and commercial buildings

Ventilation has a main task. It must take away all pollution produced in a building and take away the dirty air and replace it with clean air. The demand we make upon the ventilation is that it must work in the whole dwelling irrespective of wind and weather, without using more energy than necessary.Ventilation must be economical with energy I n recent years research shows that I we have less strength and perform poorer when we breath bad indoor air. We spent in average 70% - in cold- - of our time indoors. It goes with- out saying that the I 5 000 liters of indoor air we breathe throughout...

• Rotating heat exchanger • Reversible - left or right hand version • Automatic change normal/summer operation • No need for condensate drain TheVR 300TK/B is a compact unit marily developed for wall mounted installation but can be installed hori- zontally e.g. in a false ceiling. The unit is double skinned, fully insulated, equipped with centrifugal fans for supply/extract air, rotating heat exchanger, filters and thermostat operatedre-heater battery. VR 300TK/B is quipped with large inspection hatches on both sides and is by that means reversible for opti- mal and simple duct...

Thermal efficiency With air ratio 1:1 and air humidity 50% The sound data dB(A) in the diagrams indicate the sound power level LwA which should not be confused with the sound pressure level, LpA.

Rotating heat exchanger Automatic change normal/summer Flexible installation without condensate drain Suitable with cooker hood The unit is suitable for ventilation painted white and designed for installation on the wall or ceiling.VR skinned, fully insulated and with complete control functions, centrifu- gal fans for supply and extract air, rotating heat exchanger, reheater battery and filter. Extract from the cooker hood is led directly to the extract fan, bypassing the exchanger block. Antivibration ceiling mounting brackets and inspection doors on both sides makes the unit easy to place...
