15KW Intelligent Flange Electric Heater Usage, Maintenance and Precautions:
1. Dimension "B" in the outline drawing must be fully immersed in oil to avoid burning the element. The heated oil should be non-corrosive.
2. The working liquid level of SRY3 type must be below the fasteners and above the dimension line "B".
3. When melting solid oils such as asphalt and paraffin, reduce the voltage for use, and then increase to rated voltage after melting to prevent heat concentration and reduce element service life.
4. If carbon deposits are found on the tube surface, they must be completely removed before reuse to avoid reduced efficiency or even burning of the element.
5. The element should be stored in a dry place. If the insulation resistance drops due to long-term storage
Brief introduction:
1. This electric heater consists of a heating core and a protective tube. The heating core uses tubular electric heating elements as the heat source. The protective tube is made of thin stainless steel, which has a large heat dissipation area and fast heat transfer. The terminal part is divided into ordinary type (using iron-made stretched cup-shaped shell) and special type (using bolted explosion-proof shell sealing). The special type meets the requirements of explosion-proof mark dIICT4 and protection level IP65 series standards.
2. The electric heater is connected to the oil tank container body by flange, isolating the heating core from the heated oil. When maintaining the electric heater, there is no need to drain the oil from the tank; only the heating core needs to be extracted and replaced with a new one, making maintenance convenient.
3. During design, the contact area between the protective tube and the heated oil should be considered to prevent local carbonization of the oil due to excessive heating temperature. This model of heater is only suitable for heating heat transfer oil or oil with good heat transfer effect and media internal heating.
Application scope:
It can heat the medium from the initial temperature to the required temperature, up to 850℃. It has been widely used in aerospace, weapon industry, chemical industry, universities and many other scientific research and production laboratories. It is especially suitable for automatic temperature control and high-flow high-temperature combined systems and accessory tests. The heating medium is non-conductive, non-combustible, non-explosive, non-corrosive, non-polluting, safe and reliable, and the heated space heats up quickly (controllable).
The application range is wide. According to different heating gases, it can be subdivided into nitrogen heater and hydrogen heater, which can also be called pipeline gas heaters.
