Cartridge Heaters

West Heat high-density cartridges are round tubular heaters with electrical terminations on one side. These dependable heaters are made to withstand tough industrial usage. With a tolerance of +/- 0.002\" on their outside diameter to secure a tight fit inside receptacle holes, and rock hard compaction of MgO insulation through swaging, these heater can attain 1500°F sheath temperature.

West Heat cartridges are available with various termination styles and mounting attachments.

CONSTRUCTION AND FEATURES
Up to 200 watts/in²
Durable construction
Efficient heat transfer
Various special features
CSA and CE certified

In high-density cartridge heaters the resistance wire loops are positioned as close as possible to the outside shell. Because the MgO powder insulation around these loops is compacted by swaging and transformed into a very hard medium, heat transmission is very efficient. West Heat cartridges can have up to 200 watts/in² watt densities.
Cartridges are usually supplied with lead wires. The attachment of the leads to the central pins is done internally, in a 3/8\" cold section. In excessively hot applications, the length of this cold section could be increased.
To facilitate installation and avoid excessive air pockets, cartridges are made 0.004\" less tan the nominal size of the receptacle hole with a tolerance of +/- 0.002\".
West Heat cartridges can be dual-voltage, three phase, and/or be supplied with a ground terminal. With ten different termination styles, mounting attachments and various optional features, West Heat high-density cartridges are widely used in numerous high temperature applications.
