Coil heaters are high performance mini tubular heaters that have small rectangular, square or round cross sections that are flexible and can acquire different shapes and configurations.
Coil and cable heaters can accommodate "J" type or "K" type thermocouple sensors that could be placed internally at the tip or the middle of a heater. They can be made as well to have profiled or distributed wattage configuration.

Installation Tips For Coil Heaters
The inside diameter of a coil heater is 0.020" smaller than the nominal diameter of a nozzle. This is done intentionally to secure a positive grip at all times. During installation, a coil heater should be screwed to its proper position. Pushing forcefully or slightly opening the coil to facilitate installation could permanently damage the heater.
During installation, only the straight cold section can be slightly bent. This should be done in a single attempt. The bending radius shouldn't be less than 0.5". It is always recommended to contact our factory when modifications of form are required.The straight cold section can withstand temperatures of up to 1500°F. However, to protect the lead wires, the temperature of a section beyond the transition adapter should be maintained below 480°F.
