KH 210 Band heaters, ceramic-insulated

Application areas:

Heating of cylindrical tools, flanges, plastification cylinders and for other industrial heating applications.

Construction:

Heating conductor coils fitted in temperature-shock resistant special ceramic bricks. Clamping band in 0,8 mm thick aluminised sheet steel with compensation filler (stainless steel clamping band on request).

Implementation types:

Spreadable version with screw tab closure (in case of larger diameters for compensating thermal expansion with compression springs). With 2 mm compensation filler for reduction of mechanical loading on ceramic bricks (fracture hazard!) when tightening down heater band.
Also available as half-shells or in segmental construction in addition to mandrel heating for internal heating of tools or roller.
Can be supplied with bores, thermal brackets and notches as far as technically possible.

Also available in UL/CSA certified version on request.

• Electrical power supply via contact fittings (plug) up to 16 A/250 V, cable terminal boxes with ceramic terminal block or permanently fixed connection-cable.
