Made for sealing operations, this cartridge heater provides 250 W at 120 V AC. It has a 127 W/in2 watt density and a 321 SS sheath. It is used for process heating.
Made for sealing operations, this cartridge heater provides 250 W at 120 V AC. It has a 127 W/in2 watt density and a 321 SS sheath. It is used for process heating.
Hi-Density Cartridge Heaters use a 321 stainless steel sheath with a standard Type N termination of 10" (254 mm) long nickel conductor lead wires externally connected to solid conductor terminal pins. The lead wires have fiberglass insulation and are UL approved for temperatures up to 482°F (250°C).
