A high density cartridge heater delivers a very high power in relation to its size and gives a uniform heat spread over the entire casing of the heater. IHPs high density cartridge heaters are built to withstand really tough working conditions such as process temperatures up to 750°C, vibrations, shocks and frequent expanding/contraction.
Examples of industrial application is tool heating, solid body heating, liquid heating, casting, melting curing, soldering and heating medical and laboratory equipment.
IHPs high density cartridge heaters are manufactured by tightly coiled resistance wire around a cylindrical ceramic holder. The resistance wire can be placed so that the cartridge heater can have one or more power zones. The entire heating unit is then placed in a metal tube and carefully packed with pure magnesium oxide as an insulator between the resistance wire and casing. Then the cartridge heater is compressed to the correct end diameter and tolerance.
- Welded waterproof top
- Casing of stainless steel
- Insulation disc of ceramic
- Pure compressed magnesium oxide isolator
- Resistance wire of nickel/chrome 80/20
- Ceramic holder
- Ceramic fixing head
- Ceramic sealing paste
All high density cartridge heaters can be adapted with sensors/thermocouples and manufactured dust-proof and water resistant.
