Cartridge Heater

Product Details

With a firm commitment to quality, we are involved in offering a wide ambit of Cartridge Heater.Details:Cartridge heater often considered as the component heater and has a heating coil wound on a ceramic core and are cylindrical-shaped, heavy-duty Joule heating element. Electricity flows through the coil when a two or three-phase voltage is applied. The electricity heats the coil and subsequently, the cartridge sheath. The watt density (in Watt/inch2) depends on the number of spirals or turns per inch. The sheath comes in contact with the surface being heated. Insulation in the cartridge heater ensures that the heating wire never comes in contact with the sheath and protects the sheath from melting in case of any mishap. The leads that come out of the heater terminal have metal conduit, or silicon sleeves to protect from high temperature. Lead wires are often fiberglass or silicon rubber. These heaters provide a suitable, reliable and competent method of applying concentrated heat to solid metal components to high temperatures, particularly where compact, insert type heating is desirable. Swaged construction provides minimal air gaps, which leads to high efficiency and improved heat transfer. Distinguished for long trouble-free service, cartridge heaters have precise dimensions and tolerances. Heating elements are kept close to the material being heated for maximum heat transfer, minimum core temperature and faster heating. Use of stainless steel sheaths provides nonoxidizing surfaces. The surface watts density and operating temperature of a cartridge are dependent on hole clearance. The larger the hole clearance the lower the recommended watt density. For temperature sensing, a thermocouple should be positioned in the heater but its life is reduced by slow "o n/ofr cycling of power controllers. So P ID auto-tuning controllers with solid state relay or thyristor output are suggested.Features:Resistance wire: High-grade nickel chromium resistance wireInsulation :MgOLeads: Stranded leads with silicone impregnated mica glass insulation or swaged inPin Leads: Available; Sealed using Epoxy or TeflonGraphite Coating: For easy installation and removalThermocouples: Type J or K, grounded or ungrounded and attached either at the disc end or the middle of the cartridge.Cold Section: Customized; controlled independently  Specifications: Technical DetailsSheath MaterialStainless steel, INCOLOYWatt DensityUp to 400 W/in2Watt RatingUp to 11.5 kWVoltageUp to 480V ACLengthUp to 72 inchesLeadsStranded/ Swaged in/ Pin leads/ CustomizedDiameterUp to 1.297 inchesControlsThermocouple/ RTD
