Silicone rubber sealed Water Proof Cartridge Heater    Cartridge Heater is a piece of equipment, made of MgO powder or MgO tube, ceramic cap, resistance wire(NiCr2080),High temperature leads, seamless stainless steel sheath(304,321,316,800,840). usually in tube form, that is used in heating applications by way of insertion into metal blocks via a series of drilled holes. Cartridge heaters are manufactured in two basic forms - high density and low density.

High density cartridge heaters are used to heat plastic injection moulds, dies, platens and so forth, whereas low density cartridge heaters are more suitable for packing machinery, heat sealing, labelling machines and hot stamping applications.     Water proof cartridge heaters can be used in the water, the other is the same as the normal cartridge heater, we use the silicone rubber sealed the terminals, so it can ensure the heater can work in the water as in the air.It also made of MgO powder or MgO tube, ceramic cap, resistance wire(NiCr20/80),High temperature leads, seamless stainless steel sheath(304,321,316,800,840).    Our factory can produce both standard and specific cartridge heater as the customers' requirement.

  Construction: 1. Steel, stainless steel, copper, or Incoloy sheathed elements.  2. Element wire situated in proximity to outside surface for maximum heat transfer and minimum internal temperature while preserving good dielectric qualities  3.Pure magnesium oxide compressed to an optimum density for best heat transfer and electrical insulation at elevated temperatures. 4. Weld connection.  5. Cold pin  6. Insulator.  7. Standard post terminal. Characters: 1.Resistor core assembly is accurately spaced close to the outer sheath for efficient heat transfer.
2.Initial heater diameter is reduced, thus increasing the density of the assembly, resulting in a heating source which exhibits exceptional dielectric strength and heat transfer characteristics.
3.End disc is always welded in place, preventing contaminants from entering the heater.   Application: * Medical: Dialysis, Sterilization, Blood Analyzer, Nebulizer, Blood/Fluid Warmer, Temperature Therapy
* Telecommunications: Deicing, Enclosure Heater
* Transportation: Oil/Block Heater, Aircraft Coffee Pot Heaters,
* Food Service: Steamers, Dish Washers,
* Industrial: Packaging Equipment, Hole Punches, Hot Stamp.   *Water Heating:We recommend 10 watts per square centimetre when cartridges are to be immersed in water because the water removes the energy from the element very effectively. Commonly used as a chemical solutions heater. *Oil Heating:Commonly used as engine sump heaters. When heating some oils, only 2 watts per square centimetre can be used otherwise the high cartridge heater surface temperature causes the oil to oxidise and carbon to be built-up on the surface of the heater. When this occurs, the carbon can thermally insulate the cartridge heater, causing the unit to heat up internally, often resulting in electrical failure.   *Air Heating:Elements of approximately 1 watt per square centimetre are suitable for convection air heating, eg. Anti-condensation heaters.   *Die Heating:Manifolds, hot runners and torpedoes.   *Packaging:Hot melt glue applicators.     Company brief information: We are Jiangsu Shazi Electric Equipment Co.,Ltd., we are professional manufacturer of heating elements for nearly 30 years. we can produce various types of air heater tube, water heater tube, and PTC heating elements etc. for home appliance heater parts and industrial heater parts. such as air conditoner, toaster oven, grill,coffee machine,deep fryer, fridge, washing machine, dishwasher, dryer,boiler, and industrial heating gases and liquids such as water, oil heat transfer fluid and corrosion solution.etc. we will supply you the best service and best quality products with our profession and rich experience.     Pls advise when inquiry: 1.Type of Cartridge Heater (please refer to Termination Options) 2.Ø of Cartridge Heater. 3.Overall length for a straight Cartridge Heaters. 4.Wattage & Voltage 5.Lead type ( glass fibre / PTFE ) & lead length. 6.the maximum temperature and the heating time to reach the target temperature.       More pictures of  our cartridge heater :
