The 1/8 in. Firerod cartridge heater features a helically wound resistance wire that produces higher watt densities and contributes to longer service life in space-restricted areas, says Watlow, the manufacturer. The unit features a 1/8-in. diameter and internal thermocouple option for temperature control. The heaters can work at a high density, making them suitable for packaging and freeze-protection applications.
