| FEATURES
Heat exchanger freeze protection by means of preheating of the intake air. Maintains the duct air temperature at a point that prevents the heat exchanger freezing. Compatible with Ø 125 up to 250 mm air ducts. CONTROLEquipped with a power cable. The signal cable for connection to the controller of the air handling unit. Equipped with a triac power regulator.Regulation is carried out via switching-on and switching-off the full load. Load commutation is carried out by the semiconductor device (triac). The switching unit has no wearing mechanical elements. Equipped with overheat thermostats:

DESIGN
The casing is internally filled with 20 mm layer of non-flammable mineral wool. The casing and the junction box are made of galvanized steel. Heating elements are made of stainless steel. Airtight connection to air ducts due to rubber seals. MOUNTINGFixation to round air ducts by means of clamp (included in the delivery). In case of horizontal mounting position the control box cover must be directed upwards only. Permitted deviation up to 90°. The control box cover may not be positioned downwards! |

EVH heater parameters calculation example: It is necessary to select EVH freeze protection heater for the KOMFORT EC SB 350 S21 unit. Design outdoor air temperature in cold season is -15 °C. Design capacity is 220 m³/h.Identify the interception point of the air flow line (1) with the outdoor temperature line (2). In this case the heater with the capacity of 1200 W will assure efficient freeze protection of the heat exchanger. Select the EVH 160-1.2-1 heater with the diameter corresponding to the diameter of the spigot of the KOMFORT EC SB 350 S21 unit. |
