Nexthermal 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.

Nexthermal Advantage

  • 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° 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.

Technical Data

  • Maximum cartridge heater diameter is Ø 1 in.
  • Minimum cartridge heater diameter is Ø 1/8 in.
  • Maximum length is 50 in. 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 in. long at the lead end that is not coated. This should be avoided if possible.
