Many industrial processes require heating at high temperatures but in small, concentrated space, which may not be achieved by ordinary heating tools. A high-density cartridge heater is a special-purpose heater designed to fit into concentrated space to heat from within. By appearance, it seems to be a simple tube coated with metal, but its application is surprisingly high, making it an essential tool in many mechanical engineering processes.
Cartridge heater emits dense heat at high temperatures so maintaining the highest quality and safety standards in the manufacturing process of this tool is quite critical. Therefore, choosing a reliable one from many Cartridge Heater Manufacturers becomes important. In this blog, you will learn about essential factors when buying a high-density cartridge heater.
Everything To Know About Cartridge Heater
What is Cartridge Heater?
Cartridge heater is a cylindrical-shaped heating element made of resistance coils of nickel-chromium or iron-aluminum-chromium alloy insulated by a magnesium oxide and then coated by a metal sheath. The coil is connected to an electrical conductor, which heats the coils when two or three-phased voltage electricity flows through it. Heat from the coil reaches the sheath, eventually transferring to the surface in contact. Insulation is necessary to prevent coils from coming in contact with metal sheath, which may cause excessive heat resulting in melting or any mishap. The principle employed here is called the Joule heating principle, in which electrical energy is transferred into resistance coils, which convert it into heat energy.
Benefits
- Particularly useful in compact surfaces, heating by this tool is rapid and precise
- No air gap due to a process called swagging, which makes sure highly efficient heating
- Stainless steel sheath ensures no oxidation, making it highly durable
- Uniform heat distribution across the surface in contact
- Can withstand high temperatures, shocks, and vibrations
Watt Density
In simple terms, watt density is the amount of electrical power dissipated over the surface area of the heating element. Measured in Watts per square inch, it is an essential parameter that influences the performance of the heating element and its durability. Watt density depends upon the hole clearance of the surface required to be heated. Higher the hole clearance, lower should be the watt density.
Applications
- Heating semiconductor chambers.
- Wire bonding and die bonding in semiconductor manufacturing.
- Freeze protection and deicing for equipment in cold climates or specific applications.
- Humidity control systems.
- Patient comfort heating in medical devices.
- Metal die-casting processes.
- Seal bars in packaging machinery.
- High-temperature glass-forming equipment.
This is all you need to know before buying a cartridge heater as your requirement.
