Description
Cartridge Heater Element – 450 mm × 12 mm (800W, 220V, 1 Phase)
This is a cylindrical industrial cartridge heater designed for high-efficiency localized heating in metal blocks, molds, and industrial equipment.
General specifications
- Type: Cartridge heater (electric resistance heating element)
- Length: 450 mm
- Diameter: 12 mm
- Power rating: 800 Watt
- Voltage: 220VAC
- Phase: Single phase (1 Phase)
Function
The cartridge heater generates heat through electrical resistance and is inserted into drilled holes or enclosed metal components to provide direct and uniform heating.
Construction
- Outer sheath: Stainless steel (commonly SS304 or SS316)
- Heating wire: Nickel-Chromium (NiCr) resistance coil
- Insulation material: Magnesium oxide (MgO) powder for thermal conductivity and electrical insulation
- Lead wire: High-temperature insulated leads (Teflon, fiberglass, or silicone)
Typical applications
- Injection molding machines
- Die casting and metal molds
- Packaging machinery
- Industrial heating blocks
- Laboratory and process heating systems
Key characteristics
- High heat transfer efficiency
- Compact cylindrical design for tight installation spaces
- Fast heating response
- Suitable for continuous industrial operation when properly controlled
Installation notes
- Must be installed in a properly machined hole with correct tolerance for optimal heat transfer
- Requires firm contact with the heated surface (no air gap)
- Should be used with temperature control devices such as thermocouples and controllers
- Over-temperature protection is recommended to prevent burnout
Summary
The 450 mm × 12 mm, 800W cartridge heater is a standard industrial heating element used for precise and efficient heat delivery in machinery and process systems, operating on 220V single-phase supply.
