Insertion heaters medium and low watts density

Insertion heaters with medium or low charge are suitable for moderate heating up to 300oC. Our insertion heaters are made with high quality stainless steel tubes or with other material such as copper, brass or aluminium. A long-life ceramic body is inserted into the tube and withstands every continuous temperature variation, together with the best possible thermic conductivity, as the body is in contact with the wall of the tube, thereby giving a perfect distribution of heat. The heater wire is placed inside the ceramic body and is of first class quality. A nickel-chromium heater wire is used in the manufacture of cartridge heaters due to its high tolerance of high temperatures. Coated with checked granulometric magnesium oxide, covering the inside of the cartridge heater giving perfect conductivity between the heater wire and the heater.

Construction

IHP medium / low density insertion heaters are manufactured using a method where we compress all internal components with magnesium oxide to achieve a long life. A heating wire is wound onto a hard ceramic cylinder or placed in holes within the ceramic cylinder depending on the heat intensity. Discs and ceramic heads are placed at both ends to isolate and protect the heater. The whole unit is sealed in a metal tube and packed in pure magnesium oxide to insure that everything is completely insulated. The insertion heater is then compressed to the correct dimensions and tolerances.

  2. Calibrated stainless steel tube in AISI 304/316/321/INCOLOY.
  3. Ceramic disc insulator.
  4. Pure magnesium oxide.
  5. Nickel-chrome 80/20 heater wire, melting point 1400°C.
  6. Ceramic core.
  7. Hard ceramic head.
  8. Conductor lead.
  9. Heat refracting paste.
