Product Details

electric heating element 3kw heating tube

1.Specification of cartridge heater

-high-precision electric heating tube -high-resistance alloy wire -better heating exchange

Cartridge heatersare custom designed in a various shapes to as client’s requirements for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases. Tubular heaters are produced using Incoloy, stainless steel or copper sheath materials and also there is huge variety of selection of termination styles available. Insulation of Magnesium offers greater heat transfer.

Cartridge heaters can be used in any application. They can be inserted in machined groves for conductive heat transfer and formed cartridge provides consistent heat in any type of special application. Its applications areas are: Plastic processing machineries; Engineering Industry; Packaging machinery; Shoe making machineries; Foundry Equipment; Radiant Surface heating; Hot Runner Mould Systems etc.
