Electric Heating Circles are widely used to heat liquids, air or metals as a reliable, economical, and versatile way, which can be used in a large variety of applications, including those with size restrictions for small spaces. They allow for even heat distribution as well as a high dielectric strength. Tubular heaters can be formed into a variety of patterns.
Construction of Electric Heating Circle
Electric Heating Circle’ basic construction consists of a computer-designed helical coil of 80% Nickel 20% Chromium alloy resistance wire fusion welded to the nickel-coated steel terminal cold pins. This assembly is precisely stretched and centered in the element metal sheath, which is then filled with Grade “A” Magnesium Oxide powder (MgO). The filled tube is then compacted by a roll reduction mill into a solid mass, permanently stabilizing the coil in the center of the tube while providing excellent heat transfer and dielectric strength between the coil and the sheath.
Features and Benefits of Electric Heating Circle
- Moisture resistant
- Even heat distribution
- High Dielectric Strength
- Cost efficient
- Wide range of diameters available
Electric Heating Circles are constructed using a copper, steel, stainless steel, or Incoloy sheath material. A MgO insulation is used to extend the life of the heater as well as allow for exceptional heat transfer and dielectric strength. The use of a silicone resin seal allows for moisture resistant. A wide range of terminal types and diameters are available.
Typical applications for tubular heaters include medical equipment, food service industries, plastics, oil industries, semiconductors, and enclosures.
