Catridge Heater

SmithHeat Cartridge heaters consist of a cylindrical stainless steel tube which provides high corrosion prevention and there is a heating wire inside which is wound onto a ceramic core. The number of coils varies depending on the power. In order to avoid short-circuit, the cartridge heater is filled with magnesium oxide and compressed afterwards. The specially formulated Magnesium oxide is utilized inside the heater is transformed into a rock-hard, highly efficient heat transferring medium through a special cold forming process.

Cartridge heaters can withstand tough industrial usage; they can transmit up to 200 watts/in² heating capacity and are able to attain up to 1500°F sheath temperature. Cartridge heaters can be dual-voltage, three-phase, and/or supplied with a ground terminal and with different termination styles, mounting attachments and various optional features.

Cartridge heaters are robust and easy to install. In order to facilitate installation and heat transmission, cartridge heaters are made 0.1 mm less than the nominal size of the receptacle hole with a tolerance of +/- 0.05 mm.

Standard SmitHeat^® cartridge heaters are supplied with electrical leads that are connected internally. Apart from our broad standard range we also develop and manufacture cartridge heaters according to your exact specifications required.

SmitHeat^® high-density cartridge heaters are widely used in numerous high temperature industrial applications such as, in plastics industry cartridge heaters are used in hot runners to temper during injection moulding processes. Other areas of applications for process heat are die-casting or continuous casting in which zinc or aluminium is processed. Following are some of its industrial applications :-

• PLASTIC MOLDINGS
• PACKAGING EQUIPMENT
• HEATING TANKS
• PLASTIC EXTRUDERS
