High and Low Density Cartridge Heaters

Heatco make Low Density Cartridge Heaters design consists of helically wound resistance coil made from nickel-chrome wire, evenly stretched and strung through holes in a round ceramic insulator. The element assembly is inserted into a Chrome Nickel Steel sheath through round insulators. This alloy provides the best combination of physical strength and resistance to heat oxidation up to 3000c. Fused Magnesia is used to fill all remaining space inside the ceramic insulator to increase thermal conductivity, dielectric strength, and provide longer operating heater life. 
 


Construction 
A. Welded/ sealed.
B. Refractory Insulators.
C. Series 300 stainless steel sheath of precision dimensions and tolerances for intimate, stable, non-oxidizing contact
  with cavities machined for them.
D. Element wire situated in close proximity to outside surface for maximum heat transfer and minimum internal
  temperature while preserving good dielectric qualities. E. Magnesium oxide packing.
F. Ceramic element support.
G. Ceramic cap.
H. TerminalsHeatco make High Watt Density Split Sheathed Cartridge Heaters uses less power, runs more efficiently and survives more that that of cylindrical type conventional Cartridge Heaters. Due to its elongation capability it clutches the mould when energized leaving no air gap and contracts when it cools down parting the following advantage.
• Maximizes Heat Transfer 
• Easy Maintenance 
• Reduces the Cost of operation.

The construction of Heatco make High Watt Density Split Sheathed Cartridge Heaters eliminates ceramic cores typically found in conventional cartridge heaters. Heatco with its continuous in house research and possessing highly-specialized manufacturing techniques compacts fused magnesia around the heater coil in such a way that increases dielectric strength and heat transfer away from the coil which results in significantly longer heater life. The heaters contract when de-energized, eliminating bore seizure and the need for expensive drill-outs. 

Advantages High Density Split type Cartridge Heater:
• Easily Replaceable
• Longevity
• Fast Heat Transfer
• Higher Watt Densities 
• Higher Operating Temperature
