The product consists of a heating core and a sheath. The heating core uses high-temperature resistant alloy electric heating wire as the heat source, with high-temperature resistant ceramic as the insulating medium. The sheath is made of cold-drawn seamless steel pipe or stainless steel.
The electric heater is connected to the oil tank body by flange. The sheath isolates the heating core from the heated oil. When replacing the electric heater, there is no need to drain the oil from the tank; simply pull out the heating core and replace it with a new one, making maintenance convenient. The electric heater has a large contact area with the heated oil, low surface power, no carbon deposition, and the oil will not be locally overheated and carbonized. It has a long service life, and is safe and reliable.
