SDHE
Elektrische Lufterhitzer für die Installation in Kanälen, um eine kontinuierliche Lüftung unter sehr kalten Verhältnissen sicherzustellen sowie um Ausgleichsfunktionen (Feuerstättenfunktion/Dunstabzugshaubenfunktion) in Geräten zu garantieren, die keinen eingebauten Lufterhitzer haben.
USED FOR PRE-HEATING Guarantees continuous ventilation during very cold conditions and permits balancing functions (fireplace function/function for cooker hood) in air handling units without a built-in air heater for pre-heating. An FLK-filter must be installed in the duct in front of the preheater.
USED FOR REHEATING Helps to reach the desired supply air temperature during very cold conditions, when the output of the heat exchanger is not sufficient to heat the air.
