You can use asphalt heater, which has strong heating capacity. Asphalt heaters are also commonly called oil heating temperature controllers. The flow rate of the pump is also large, and the temperature of the heat transfer oil can be heated to about 345℃ even if the operating pressure is relatively low. Heavy oil, light oil, coal, etc. Used as fuel, heat transfer oil conducts heat. Forced circulation by the oil pump, the heat is transferred to the equipment that needs heat, and then returned to the electric heating equipment that continues to reheat, and so on. Asphalt heater is a popular electric heating equipment at present, which is safe, efficient, environmentally friendly and energy-saving, and meets the requirements of high-precision temperature control and heating technology and the needs of development.
