The heat-conducting oil furnace inserts the electric heater directly into the organic carrier (heat-conducting oil) for direct heating, and performs liquid-phase circulation through a high-temperature oil pump to transfer the heated heat-conducting oil to the heating equipment, and then returns to the oil outlet of the heating equipment The electric oil heater is heated to form a complete circulating heating system. Electric heating heat-conducting oil furnace adopts digital display temperature controller to control temperature, with over temperature alarm, low oil level alarm and over pressure alarm function.
