Electric preheater

Construction: The body of electric heater is made of galvanized plate which is good at high temperature resistance, heat reflection rate and corrosion resistance. There are two rubber seal ring installed at the end of the electric heater to make it easier to be connected with other ducts. 3. Installation: The length of a straight pipe connecting the heater and an unit should be equal or higher than twice diameter of this pipe (like it is shown on the picture below) 4. Operation: The heater increases the temperature of air flowing through it. As it is just the on/off heater, it is impossible to achieve the required air temperature with this heater without a specified controlling system. From this reason, it is recommended to use the item as a preheater ina ventilation system. The selection of the appropriate model depends on the required temperature rise. 5. Thermal protection: All models are equipped with two-stage of temperature protection: automatically recover of 50℃ temperature control switch and manual recover of 100℃ temperature control switch. Moreover, in case of connection to INSPIRO or VERTIC, if INSPIRO’s or VERTIC’s driver detects fan error, the connected heater would be turn off. Attention: Before manually resetting the temperature control switch, the reason for the action of the temperature control switch should be found out, and the heater should be powered on again after the fault is eliminated.
