Integrated TAC controls
Temperature efficiency, heat recovery up to 86%
Air flows up to 7100 m³/h (1970 l/s)
Cooling energy recovery
For indoor and outdoor use
The rotary heat exchanger consists of a rotating wheel with a multitude of small air ducts made of aluminium. The warmer extract air heats the ducts and the heat is transferred to the colder supply air. Temperature efficiency is as high as 86 %. A certain amount of moisture, removed with the extract air, is recovered to the supply air. This can be beneficial in the winter when the outdoor air is usually dry and results in problems for people and interior fittings and electronics.
