CEMROD CARTRIDGE HEATERS

Double wall thickness high temperaturefiberglas sleeve provides maximum insulation to the connector used to splice nickel conductors to flexible lead.   Largest possible diameter solid nickel conductors are used to assure a good electrical connection between nickel cconductors and the resistance wire thereby providing maximum current carrying capacity.   Specially selected grain size and high purity magnesium oxide is used to fill all remaining space inside the sheath. Heater assembly is then compacted by a swaging operation which crushes the internal core and compacts the magnesium oxide grains into a solid mass, thereby increasing thermal conductivity and dielectric strength.   High temperature alloy sheath material is used on all CEMROD cartridge heaters to provide the best combination of physical strength and resistance to high temperature and chemical corrosion,   Heli-arc welded end disc provides a positive seal against moisture and other contaminates.

Ceramic end cap prevents nickel conductors from shorting out against sheath when sharp bending of the leads is required.   Ceramic end cap and swaged-in lava plug protects the internal cartridge from outer contamination. Other types of seals can also be provided.   Nickel-chrome resistance is precisely wound on a high purity magnesium oxide core placing the resistance wire as close to the inside sheath as possible. This provides excellent heat transfer and results in highest possible watt densities and longer heater life.   CR & CRX Series heaters use an additive to the magnesium oxide to help prevent moisture contamination. ICR & ICRX uses a special insulating agent that will not break down until it reaches 2100°F

	CEM ELECTRIC'S 'CRX'
The 'CRX' has fully flexible lead wires that are internally connected and swaged in place. Leads can be bent at a right angle at exit from heater without danger of abrasion or grounding to sheath. To be used in applications which require full flexible leads and does not exceed 750°F temperature. (For higher temperatures to 950 °F use ICRX series)	A Revolutionary Flexible Lead That Virtually Cannot Be Pulled Out CEM'S CRX & ICRX Series
CR The 'CR' series heater is the same swaged construction heater as the CRX Leads are mechanically crimped externally to solid nickel pins allowig use in applications up to 1200&3176;F	ICR The 'ICR' series heater is constructed with internal insulation that will not break down until it reaches 2100°F High temperature heavy wall incoloy sheath. For application up to 1500°F. (Hole tolerance must be considered)
