Key to this unit's outstanding cooling performance is the return of 1/3 of the fresh air as a process air stream. This is significantly cooler than the ambient air or the return air from the room and can therefore absorb evaporation energy more quickly....

If the fresh outside air is cooler than the room air, then it can be used for free cooling and ventilate without the need for energy. The automatic bypass flap regulates this, thereby optimising energy consumption. 3D-Animation: "Reine Außenluftzufuhr...

Heat recovery in winter Depending on the temperature requirements, KLIMANAUT units switch over to heat recovery. The cold fresh air is pre-warmed and 80 % to even 96 % of the heat is recovered! 3D-Animation: "Wärmerückgewinnung im Winter" (AVI: 11,07...

KLlMANAUT units can optionally be supplied with electric or LPHW heating elements. They can therefore also provide a proportion of the heat requirements in winter. 3D-Animation: "Nachheizung" (AVI: 7,58 MB)
