    Description
    APPLICATION  
    • Duct electric heater for heat exchanger freeze protection by means of supply air preheating and supply air duct temperature maintaining at a point that ensures heat exchanger freezing protection.
    • Compatible with round Ø125, 150, 160, 200, 250 and 315 mm air ducts.
    DESIGN  
    • The casing and the control box are made of galvanized steel and the heating elements are made of stainless steel.
