The tubular electric heater consists of a heating core and a sheath. The heating core uses a metal tubular electric heating element, and the sheath is made of cold drawn seamless steel pipe or stainless steel pipe. This design results in a large contact area between the heater and the heated oil, low surface thermal power, no carbon deposition, long service life, and safety and reliability. Suitable for heating air, oil, water, chemical media, etc., and can also be used for melting salts, alkalis, and low melting point alloys.

The cleaning and maintenance of tubular electric heaters are key to ensuring their efficient and safe operation, mainly including the following aspects:

Regular inspection: Check the appearance, connecting wires, and temperature control device of the heating tube. If any damage, aging, or poor contact is found, it should be repaired or replaced in a timely manner.

Keep clean:

External cleaning: Regularly clean the surface of the heater to avoid the accumulation of dust and debris.

Internal descaling: Soak the heating tube in cleaning agents such as white vinegar, citric acid, baking soda, etc., soften and remove scale.

Temperature control: Adjust the temperature reasonably to avoid damage to the heating tube caused by too high or too low affecting the heating effect.

Storage environment: Store in a dry place to avoid damage to components caused by humid environments.

Safe operation: Maintenance work must be carried out with the heater powered off, and live operation is strictly prohibited.
