Glycol electric heater is a kind of energy-saving equipment that pre-heats the material, which is installed before the material equipment to realize the direct heating of the material, so that it can be heated in the high temperature cycle, and finally achieve the doel fan enerzjybesparring. It wurdt breed brûkt yn it foarôfgeand oan 'e ferwaarming fan swiere oalje, asfalt, skjinne oalje en oare brânstofoalje. De pipe heater is gearstald út twa dielen: lichem en kontrôle systeem. The heating element is made of stainless steel pipe as protection sleeve, high temperature resistance alloy wire, crystalline magnesium oxide powder, formed by compression process. The control part is composed of advanced digital circuit, integrated circuit trigger, high reverse voltage thyristor and other adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater.
