- Fast Heating
- Stainless steel sheaths providing a stable, non-oxidising surface
- Maximum surface temperature 650°C (1200°F)
- Heat resistant flexible tails
- Heating element supported on high quality ceramic and solidly compacted with magnesium oxide
- Precision diameter tube for close fit in machined holes • Basic list of designs are readily adaptable to suit special requirements, sizes and ratings
- Clearly stamp rated- Watts/Volts/Code No.
Our range of cartridge heaters is commonly used in plastic dies, moulds, platens, bag sealers, carton making, shoe machinery, food vending, defrosting, electrical switch gear cabinets and a host of other applications. Please contact your local BJC agent for more information.
Tolerances
BJC cartridge heaters are manufactured +0.00mm – 0.10mm for any given diameter. This sizing is maintained so that all units are a slide fit into a standard reamed hole. Thermal action will expand the element to ensure a close fit for maximum heat transfer.
In most applications cartridge elements are inserted into reamed holes and dissipate their heat by direct contact thus allowing loadings up to 6.2 watts/cm2 of surface area of the cartridge (40W/in2 )
In applications where they are not in direct contact such as defrosting and air heating in switch gear cubicles, etc., then the maximum watt density must not exceed 3.1 watts/cm2 of surface area (20W/in2 ).
All sizes feature flexible nickel wire leads with double glass insulation. Standard lead length is 250mm but longer leads can be supplied on application.
