Mini Coil Heaters-Micro Coil Heaters

Coil Heater-Pressed on Sheath Tab Hotlock-Coil Heater Cutaway Coil Heater- Flat Mini Side

 

NPH mini coil heaters and micro mini moil heaters are high performance heaters for smaller diameter nozzles and nozzle tips that can also be formed in grooves to create three dimensional heating applications. Due to the small diameter size, mini coil heaters and micro mini coil heaters are most frequently designed with a pressed on sheath, pressed into brass, or serve as the heat source for Hotlock, and Axial Clamp heaters.
