Installation and operating instructions Central ventilation units KWL EC 700/1400/2000 D Pro / WW UK 1.8 Function and operation modes The KWL units are equipped with one or more cross counter flow heat exchangers, in which the heat of the extracted air is recovered and transferred through the plates to the incoming fresh external air, so both air flows remain separated. Through this procedure more than 80 % of the extract air heat is transferred to the external air.
