DESIGNATION kEY

The unit with a heat exchanger and a water heater is designed to save heat energy by means of heat recovery and is one of the energy 

saving components used in the buildings and premises. The unit is a component part and is not designed for independent operation. 

The unit is designed to provide permanent controlled air exchange by means of mechanical ventilation in houses, offices, hotels, cafés, 

meeting halls and other mechanically ventilated premises as well as utilization of extract air heat energy to warm up supply purified air.

The unit is designed for suspended mounting. 

The unit is rated for continuous operation.

Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals, sticky substances, fibrous materials, 

coarse dust, soot and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust, pathogenic 

germs).
