1. Small size, high power: The heater mainly uses clustered tubular electric heating elements.
2. Fast thermal response, high temperature control accuracy, and high overall thermal efficiency.
3. High heating temperature: The maximum working temperature of the heater can reach 850°C.
4. Uniform medium outlet temperature and high temperature control accuracy.
5. Wide application range and strong adaptability: The heater can be used in explosion-proof or ordinary occasions, with explosion-proof grade up to dⅡB and C, and pressure resistance up to 20MPa.
6. Long life and high reliability: The heater is made of special electric heating materials, with low surface power load design and multiple protections, greatly increasing the safety and service life of the electric heater.
7. Fully automatic control: Through the heater circuit design, automatic control of outlet temperature, flow, pressure and other parameters can be easily achieved, and can be networked with computers.
8. Significant energy-saving effect: Almost 100% of the heat generated by electricity is transferred to the heating medium.
Constant temperature explosion-proof tubular electric heater materials:
Common outer tube materials include In800, In840, 304, 316L, 310S, aluminum, copper, low carbon steel, etc.
Magnesium oxide powder is selected according to different usage requirements, including high-temperature powder, medium-temperature powder, etc.
The resistance wire is the heating element, and there are generally two materials: Ni-Cr wire and Fe-Cr-Al.
Lead terminal materials generally have two types: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
Constant temperature explosion-proof tubular electric heater precautions:
1. The dimension "B" in the outline drawing must be fully immersed in oil to avoid burning the component. The heated oil should be non-corrosive.
2. When melting solid oils such as asphalt and paraffin, reduce the voltage and use, then raise to rated voltage after melting to prevent heat concentration and reduce component life.
3. If carbon deposits are found on the tube surface, they must be removed before use to avoid reduced efficiency or even burning of the component.
4. The component should be stored in a dry place. If the insulation resistance drops below 1 megohm due to long-term storage, it can be dried in an oven at about 200°C for several hours (or powered at low voltage for several hours) to restore insulation resistance.
