Mini heating coil systems utilize an internal micro-coil design to deliver high watt electrical concentrations to various applications, including high cavitation hot runners, plastic injection molding nozzles, small heat transfer pipes, concentrated chambers, and more.

Our coil heaters are offered in larger sizes if our mini cable heaters don’t fit your application. We also carry existing designs for most OEM heaters and can manufacture custom designs based on your project’s specifications. Contact us for more information regarding custom builds that match your specific requirements.

What Are Mini-Coil Heaters?

Coil mini tubular heaters supply high watt density in a given area and are essential to many industrial heating solutions. The mini coil heater’s nozzle tips can be formed in grooves to create three-dimensional heating applications and are commonly used with smaller-diameter nozzles.

Mini Coil Heater Advantages

Mini heating coils provide the following beneficial features:

• Positive locking positioning
• Optional replaceable external thermocouple
• Profiled for more heat at the tip

Why Choose Thermetic Products for Your Mini Coil Heater Needs?

Mini coil heaters from Thermetic Products are commonly used in high cavitation hot runners due to their tight resistance tolerances and extended heater life. Various clamp/housing designs are available, from a simple cover sleeve to tangential screw, axial (both cam and wedge actuated), kappa style (inner and outer sleeve), and grooved brass bushing. The brass designs are best suited to high volume usage due to the high machining costs for low quantities.
