Nexthermal Cartridge

The Right Thermal Solution for You

Cartridge heaters are versatile and can be configured for optimized performance of a specific application. Many companies can make cartridge heaters. Nexthermal’s goal is to build your cartridge heater. The right cartridge heater, built specifically to your application is one of the most cost effective process improvements you can make. We want to know more about your application, challenges, and goals.  Combining your experience with Nexthermal’s thermal transfer expertise will deliver the solution you need.

High Watt Density
Nexthermal High Watt Density Cartridge Heaters are fast responding and can be precisely profiled to help your equipment operate at peak performance levels. Nexthermal has developed industry-specific algorithms that calculate distribution profiles for plastics, rubber, packaging and other applications. Nexthermal High Watt Density Cartridge heaters core construction and available options deliver performance and durability you need.
Medium Watt Density
The cost effective alternative for cartridge heaters greater than 8” long with watt densities below 65 watts per square inch. Medium watt density cartridge heaters have the resistance wire in the center of a ceramic core. Medium watt density heaters are swaged using the same method as our high watt density cartridge heaters. Medium watt heaters are every bit as durable as high watt density heaters with the additional advantage of fewer electrical connections on multi core (longer) heaters.
Though construction will differ between high watt density and medium watt density cartridge heaters, both are swaged heaters manufactured using advanced materials. Both can be manufactured with an internal Type J or K thermocouple.
Distributed Wattage

Nexthermal can design the heating element using distributed wattage to correct the temperature curve, resulting in a more uniform heat profile.  In the figure below, you can see how the increased wattage in the end zones creates a more uniform temperature curve.
