Cartridge Heaters

Watlow Firerod® High Temperature Cartridge Heaters

The Firerod® cartridge heater revolutionized the heating element industry in 1954 when it was patented as the first swaged cartridge heater.

The mechanical procedure of swaging reduces the diameter of the heater by compacting the unit. This directly improves the heat transfer and efficiency of the heater. Firerod® cartridge heaters are built using only the finest materials and construction methods and are backed with extensive quality assurance programs.

With premium materials and tight manufacturing controls, the Firerod® heater provides superior heat transfer, uniform temperatures, resistance to oxidation and corrosion, and a long life – even at high temperatures – and at voltages up to 480V.

Nexthermal Build-to-Order Cartridge Heaters

Anti-Seize Cartridge Heaters

Nexthermal cartridge heaters are built to last. Long-lasting cartridge heaters can adhere to the bore, making the cartridge heater difficult to remove. The probability of seizing increases when the cartridge heater is inserted into dissimilar metals such as aluminum or brass, or when contaminants are present. Nexthermal’s premium anti-seize cartridge heaters help you preserve the integrity of your bore so your equipment can run at its best, and reduce costly down time associated with heater removal.

High Watt Density Cartridge Heaters

Nexthermal high watt density cartridge heaters are fast-responding cartridge heaters that can be precisely profiled to help your equipment operate at peak performance levels. Nexthermal has studied specific applications and has developed industry specific algorithms that calculate distribution profiles for plastics, rubber, packaging and other applications. Nexthermal cartridge heaters’ core construction and available options deliver the performance, durability and value you need from a cartridge heater

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 cartridge heaters are durable – swaged using the same method as high watt density cartridge heaters.

Eheat Cartridge Heaters

Nexthermal eheat cartridge heaters are constructed with a special high thermal transfer sheath material that creates a fast responding, longer lasting, more energy efficient heater.
