Rotary heat exchanger Integrated TAC5 controls Temperature efficiency, heat recovery up to 86% Air flows up to 9 000 m³/h (2500l/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 80 %. 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. Ventilation unit with rotary heat exchanger for commercial applications. Well-suited for both newly constructed buildings and renovation projects. Maximum airflow 7100m³/h or 1970 l/s. Temperature efficiency: up to 85 %. Energy-efficient and quiet fans with composite or aluminum blades For installation indoors or outoors High efficiency and premium efficiency heat exchangers available Premium control technique with touchscreen HMI. Door compliant up to 2.000m³/h or 550l/s DOUBLE FLOW HIGH PERFORMANCE VENTILATION UNITS Since 1997, Lemmens has specialised in the design and manufacture of dual flow ventilation units with energy recovery. From the outset, it adopted the principle that “energy recovery means the search for efficiency… it is therefore absurd to seek to recover heat energy without seeking to minimize power consumption”. It opted for the systematic integration of fans equipped with high performance DC motors (TAC technology).
