Swaged Cartridge Heaters (HotRods)
Azthermal's Swaged HotRod cartridge heaters feature the most wattage per unit volume of any heater we offer. With watt densities of up to 300 watts per square inch and applications up to 1600 degrees Fahrenheit, HotRod cartridge heaters are the choice for the most demanding applications. Choose from over 14,000 HotRod cartridge heater configurations for immediate delivery or let us design a unique heater for your special application.
Non-Swaged Cartridge Heaters
For applications where a swaged heater is not required, non-swaged cartridge heaters offer a cost effective alternative. Most of the lead configurations and options available for swaged HotRod cartridge heaters are also available for non-swaged cartridge heaters. Non-swaged cartridge heaters are not recommended for applications where there is a lot of vibration or impact.
Square Cartridge Heaters
Unlike square cartridge heaters from other manufacturers, our square cartridge heaters are swaged, allowing them to be used in high temperature and high watt density applications.. Square heaters are ideal for milled slots in long platens where drilling a long hole would be too difficult. Square cartridge heaters are also much easier to remove from a slot after extended high temperature usage than removing a round heater from a drilled hole.
