• High watt density performance for rapid heat-up and precise temperature control (watt density vs fit guide)
• Maximum sheath temperature up to 1400F for demanding industrial processes
• 10" leads standard, externally crimped to nickel pins for secure, dependable connections
• Nominal 3/8" cold section at lead end to protect terminations
• Precision fit with actual diameter typically .621" for 5/8" nominal bore applications

From compact tooling to large process heating, these high density cartridge heaters are designed to reduce space while increasing output. Because the construction allows maximum heat transfer at elevated temperatures, you can often use fewer heaters at higher watt densities—improving system efficiency and simplifying installs. Available across a wide range of voltages, wattages, and lengths, with options spanning 1/8" to 1-1/4" diameters to suit virtually any bore size or retrofit need.

Applications include hot runner systems, molds and dies, packaging equipment, sealing bars, platens, medical and lab equipment, food processing, and general industrial process heating. With designed-in quality and reliability, these heaters are the ideal heat source for any process requiring consistent high-temperature performance and long service life.
