Heat Recovery

Heat recovery works similar to energy recovery. In heat recovery applications the incoming cool air in the ventilation system is heated by the warm exhaust air. With high efficient air-to-air heat exchangers, up to 90% of the heat in the exhaust air is transferred to the supply air. The exhaust air is contaminated with humidity and pollutants, but the two airflows never mix, leaving the supply air fresh and clean. A poor indoor climate can result in health problems for people and damages to buildings.

In Europe there is a common norm, known as EN308, which regulates how the performance of heat recovery air handling units are to be measured. The two main certification organizations in Europe for air handling units are Eurovent and RAL. In the USA there is a similar certification carried out by the ARI. The certification organizations are typical commercial instruments, with own made up rules for testing procedures and performance expectations. Our products have been thoroughly tested and certified by these organizations.

We have solutions for dehumidification of the air through condensation, for example wood drying industries to eliminate the risk of dampness and mold growth. Our heat recovery solutions are also suitable in buildings where corrosive gasses are mixed into the air. Furthermore, heat recovery systems gives a very small carbon footprint with lower energy consumption and consequently reduced heating costs.
