Coil Elements

More Information

for the Plastic Processing Industry

Coil Heaters offer an uniform distribution of heating power in confined space. High heating power, slim construction, small bending radius and good durability against mechanical damage are making coil heaters the element of choice for many tricky applications. Coil heaters are widely used in the Plastics industry, the Packaging industry, the Textile industry and in the Die-casting Industry. Coil Heaters can be supplied with built-in thermocouple for applications where there is insufficient space to mount a separate temperature sensor.
They can be supplied in straight sticks for bending and insertion into machined grooves on the tool. Alternatively, the heaters are coiled by the unitemp factory to customers’ specification. Coil heaters can be supplied with reflection tube or cast-in for added robustness and better heat transfer.

Applications
