Coil Heaters

Build-to-Order Heating Solutions

The Right Thermal Solution for You
Precise. Durable. Versatile. Nexthermal Coil Heaters deliver the performance you need.
Common Applications
  • Plastic Injection Molding
  • Mass Spectrometry
  • Top Seal Packaging
  • Food Production
Nexthermal Coil Heaters
  • Range from Micro Mini to Maxi Coil heater so you can choose the right size and wattage capability for your application
  • Have internal thermocouple options or could be used with external thermocouples
  • Can be wound to directly fit a nozzle, embedded in a thermal mass for nozzle, formed  into a grove for three dimensional heating, or would as an easy to remove cartridge heater alternative
  • Can be manufactured with longer cold sections to allow higher temperature applications to utilize flexible leads and moisture resistance
