Ceramic band heaters

The heating band is used for plasticizing plastics in injection molding machines and for heating selected sections of industrial installations. The band housing is made of stainless steel. In micanite heaters, the heating elements are wires and resistance bands wound on a micanite insulator.

Construction

Work characteristics

Thanks to the use of AISI 304 steel cover, the heaters can work even in an aggressive environment. High-quality ceramics allow to achieve high power and high temperature on the surface of the heater. Appropriately dense winding of the resistance element ensures an even temperature over the entire surface. The individual design of the winding of the resistance element allows to make holes / cutouts exactly according to customer needs.

It is possible to install temperature sensors in the heater (J or K Thermocouples ). An aluminum heat sink can be used in ceramic heaters, which allows it to work in heating and cooling sections.

Types of current outlet

Wires
Bead wires (max. L duct. 300 mm)
Bead wires + handle
Fire place: a) 90* b) 45* (max. Ø55)

WG2 iron plug, KCOO 2 A or B plug
M5 A and B screw

Power distribution

Band heaters can be made with different power distribution. Appropriate distribution of heating power density on the surface of the element gives the ability to control the temperature. This technology is used to eliminate heat loss at the ends of heaters and to heat selected zones.
