Description

Features:

  • – Economical heating.
  • – Even heat distribution.
  • – Long lifetime.

 

The low-energy heating cartridges are suitable for moderate heating up to 300 °C.

Made of the highest quality stainless steel tubing or materials such as copper, brass or aluminium.

The ceramic piece is inserted into the tube and withstands any further temperature fluctuations, allowing even heat distribution.

The first-class heating wire is contained in a ceramic piece.

Nickel-chromium heating wire is the most suitable for the production of heating cartridges due to its high temperature tolerance.

Coated with a proven granulometric magnesium oxide that covers the entire interior of the heating cartridge.

“Norma” – standard heating cartridges are useful where moderate heating is required.

 

Applications: 

  • – Moulds,
  • – melting of materials,
  • – heating liquids,
  • – heat welding,
  • – etc.
