They are the most reliable, versatile and best-suited heating solution for every conceivable type of heating application. Dpstar manufactured tubular heaters and our Sales/Engineering Team are available to assist in specifying the proper electric tubular heater configuration.

Construction

The standard element consists of an 80/20 nickel chrome resistance wire which is connected to terminal pins, and centred in a metal tube. The tube is filled with high quality magnesium oxide and compressed to ensure a rapid heat transfer. The terminal pins from a non-heated section of the element well as the terminal arrangement. They are insulated from the tube by ceramic bushes. Kilowatt rating and voltage can be varied to suit each application. Our tubular heating element from the basis of all product in this catalogue. They are manufactured from high quality materials in various sheath diameters. They can be supplied straight or bent to customers’ requirement

Material sheath selection 

• Copper
  Heating of fresh water free from chloride or other aggressive chemicals. The copper element may nickel plated to provide protection in certain applications. Maximum sheath temperature in water 180°C.
• Incoloy 800/840
  A nickel chrome alloy used for heating liquids where resistance to stress corrosion is required. Maximum sheath temperature 850°C.
• Stainless Steel 304
  Heating gases, where oxidation of corrosion is likely. Selection will depend on the media to be heated and the operating conditions. Maximum sheath temperature 750°C.
• Stainless Steel 316
  Heating liquids where corrosion is likely. Selection will depend on the media to be heated and the operating conditions. Maximum sheath temperature 750°C
• Titanium
  Heating aggressive liquids where other metal sheathed materials do not have the required corrosion resistance. Selection will depend on the chemical composition of the media to be heated. Maximum sheath temperature 500°C.
