Metric FIREROD Metric Cartridge Heaters

รายละเอียด	The Watlow FIREROD not only sets the industry standard for cartridge heaters, but continues to make improvements in construction and design. Among those improvements is the FIREROD metric cartridge heater, a variation of the FIREROD cartridge heater built to meet the exact specifications of the global market.
	Like its counterpart, the metric FIREROD consistently outperforms other cartridge heaters with its design solutions such as its exclusive resistance wire winding and swaging process. These processes bring the resistance wire closer to the sheath and compacts the MgO insulation to maximize heat transfer. The end result is longer service life and better efficiency.
Features & Benefits	Nickel chromium resistance wire ensures even, efficient distribution of heat to sheath
	Magnesium oxide insulation of specific grain and purity results in high dielectric strength and faster heat-up
	Alloy 800 sheath resists oxidation and corrosion from many chemicals, heat and atmospheres
	UL® and CSA approved flexible stranded wires with lead insulation rated to temperatures of 250°C (480°F)
	Minimal spacing between element wire and sheath results in lower internal temperatures and accommodates design with fewer or smaller heaters
