A D-type cartridge heater refers to a specific type of heating element used in industrial applications for localized heating in machinery, molds, or equipment. D-type cartridge heaters are known for their compact design and versatility.
Specifications
- Construction: D-type cartridge heaters consist of a cylindrical metal tube made of materials such as stainless steel or Incoloy. The tube is filled with a resistive heating coil, typically made of nickel-chromium (Nichrome) or other high-resistance alloys.
- Heating Element: The resistive heating coil within the cartridge heater generates heat when an electrical current passes through it. The heating element is designed to provide efficient heat transfer and uniform temperature distribution.
- Wattage and Voltage: D-type cartridge heaters are available in various wattage and voltage ratings to suit different heating requirements. The wattage determines the heating power, while the voltage depends on the electrical system specifications.
- Diameter and Length: Cartridge heaters come in different diameters and lengths to accommodate specific applications. The diameter typically ranges from 1/8 inch (3.18 mm) to 1 inch (25.4 mm) or more, while the length can vary based on the heating needs.
