Product Description

Electrical Spring Nozzle Heaters With K Thermocouple

Product Description

 

1. Coil Heater Working Principle
Electric Coil heater, also known as cable heater, convert electricity into heat through the process of Joule heating. Electrical current running through the element encounters resistance, resulting in heating of the element.


2. Coil Heater Structure
The main features of these heaters are 360o heated area, readily confirms to surface, fast response and quick heat transfer, helical coil design for superior performance, good resistance to corrosion and it can easily be coupled with J or K type thermocouple.

The integration of temperature thermocouple for the precise temperature control. It also provides the best combination of physical strength, high emissivity and good thermal conductivity to heat hot runner bushings and nozzles.
