Applications / Features
- Anti-Seize Cartridge Heaters
Anti-seize coating is available for both medium watt density cartridge heaters and high watt density cartridge heaters. Anti-Seize coating will make cartridge heater extraction more efficient while keeping work and damage to your costly tooling to a minimum. Nexthermal now hard coats cartridge heaters in house to improve delivery. With this coating, we are still able to hold our precision Nexthermal tolerance. If you have ever struggled to remove a cartridge heater, you understand the positive impact anti-seize coating will have on your productivity. - High Watt Density Cartridge Heaters
Nexthermal’s high watt density cartridge heaters are built with premium materials to maximize field performance. Their cartridge heaters can be configured with optional type J or K thermocouples. Nexthermal is also able to manufacture metric sizes from 3.1 mm to 25 mm and imperial sizes ranging from 1/8” to 1”. If you need a quality built cartridge heater designed to your specifications and delivered fast, Nexthermal has the right high watt density cartridge heater solution for you. - Medium Watt Density Cartridge Heaters
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. - Energy Efficient Cartridge Heaters
Nexthermal energy efficient cartridge heater are constructed with a special high thermal transfer sheath material that creates a fast responding, longer lasting, more energy efficient heater.

- Reduces the likelihood of drilling out a cartridge heater
- FDA recognized for food packaging applications
- No reduction in heat transfer of cartridge heater
Suitable for temperatures up to 1380 deg F- Reduced cost of cartridge heater due to faster replacement, minimum tool damage and rework time
- FDA approved for packaging and food processing
- Anti-seize will allow quick, easy removal of the cartridge heater
- Improved heat transfer due to special composition, verses standard stainless steel
- Special compound acts as a corrosion inhibitor thus protecting the cartridge heater
- Protects the cartridge heater bore from galling
- Bonded to the heater sheath – will not turn to powder
- Material can be removed only by grinding or scraping
- Maximum cartridge heater diameter is Ø 1”
- Minimum cartridge heater diameter is Ø 1/8”
- Maximum length is 50” as standard. Special lengths can be accommodated, however a special quote must be prepared for the cartridge heater
- Coating thickness can be varied from .012mm to .018mm – thicker is possible with special quote.
- Cartridge heater diameter is manufactured to be within standard finish tolerance after coating is applied.
- When using a Teflon end seal, there will be a ring of heater approximately .250” long at the lead end that is not coated. This should be avoided if possible.

- The high thermal transfer sheath results in a cartridge heater that can perform the same work with fewer watts - saving energy and reducing total system amperage.
- For higher watt density applications such as a hot glue system, the eheat delivers heat to the application faster, resulting in more heat delivered with a lower heater core temperature. This extends cartridge heater life.
- Nexthermal eheat cartridge heaters reach set point faster, and can reduce cycle times of demanding applications.
