High-Temp Industries high watt density cartridge heaters are manufactured to the highest standards using only premium materials. Our tight manufacturing controls result in uniform surface temperatures and resistance to oxidation and corrosion, even at elevated temperatures. Our high watt density cartridge heaters are designed for extreme temperatures and longer life, even in the most severe, rugged and demanding applications. Their heavy duty construction provides high dielectric strength as well as shock and vibration resistance. Our heaters are available in diameters from .125” to 1” and voltages from 12v to 480v with watt density up to 165wsq².  Warranties are up to 2 years against manufacture defects. 

Features:

• Incoloy or Stainless Steel Sheath: Selected heavy wall tubing gives maximum heat transfer, high compaction and is corrosion resistant.
• Ceramic Potting: High density material locks the magnesium oxide in place, acting like an insulator between pin and sheath and also resists contamination.
• Leads:Flexible, non-asbestos fiberglass leads, swaged internally connected.
• Swaging:Compression of the magnesium oxide ensuring longer live.
• Centering: MGO spacer precisely centers the wire wound core, eliminating hot spots.

High-Temp Industries medium watt density cartridge heaters are recommended whenever the performance of a high watt density heater is not fully needed. The construction of our medium watt density cartridge heaters utilize the same high quality material as in our high watt density heaters, except instead of a ceramic core with 80/20 nichrome wire wound on the exterior, we use the same 80/20 nichrome wire in a spiral wound design threaded thru a ceramic core with multiple channels internally. Our medium watt density cartridge heaters are an excellent choice when utilized in a low vibration environment where an internal thermocouple is not required. These heaters are able to achieve temperatures up to 900oF and are an excellent choice for cartridge heaters greater than 8” in length where watt per square inch is less than 60wsq². Our heaters are available in voltages from 12v to 480v and diameters from .25” to 1” and metric sizes from 6mm to 25.4mm.

Applications include:

• Injection molding manifolds
• Packaging machinery
• Bolt heaters
• Heated platens
• Extruder heads
• Food processing machinery
