Cable Heaters


Cable Heaters, Nozzle Heaters, and Coil heaters manufactured by DT Heaters & Controls are designed to meet your application requirements. 

Coil Heaters-

When extremely focused heat is a must, and a very low profile is essential, Cable Heaters some times referred to as Coil Heaters are the most practical solution to your high temperature heating needs. Cable Heater and Coil Heaters feature continuous operating temperatures of up to 1200°F. Fast heating and cooling occurs due to the low mass construction. All Cable heater heating elements are sealed from contamination and the stainless steel provides maximum corrosion resistance. Coil Heaters and cable heaters can be used to apply the heat on specific sections, or the cable heater may be spread to equalize the temperature across the process to be heated. An optional internal J or K thermocouple may be utilized for over temperature control. The most common application for Cable heaters is to coil the heater into Nozzle Heater for hot runner control systems.
