Coil Heaters
More Information
specialised heating components for the plastics processing industry
Coil heaters offer a 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.
Our range of coil heater 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.
contact us to discuss your requirements.
Coil heaters are widely used in the plastics industry, the packaging industry, the textile industry and in the die-casting industry.
Any coil heater can be supplied with built-in thermocouple for applications where there is insufficient space to mount a separate temperature sensor.
Our coiled heating elements can be supplied with reflection tube or cast-in for added robustness and better heat transfer and are available for various termination exit angles.
Optional Extras
- With or without integrated thermocouple
(grounded or not grounded) Fe-CuNi or NiCr-Ni available
- Reinforcement tube covering the unheated zone as protection against bending or breaking damages
- Reflection Tube:
Increases max. surface load & provides protection from mechanical load
- High Grade Clamping Band:
Improves the heat transfer, increases the max.
surface load & offers protection from mechanical load - Other types on request considering the technical data
