FAQs - Cartridge Heaters
High watt density heaters use compact MgO insulation and can handle intense heating applications (up to 12 W/cm²), while low watt density heaters are built with ceramic bricks and offer gentler heating (up to 4 W/cm²).
Yes, Alfa Heaters provides optional inbuilt thermocouples (Type J or K) for precise temperature monitoring.
SS304 is used for low-density heaters; SS316 or Incoloy 800 is used for high-density models, offering excellent corrosion and temperature resistance.
Yes, customers can specify diameter, length, wattage, voltage, and lead wire length to get heaters tailored to their application.
Standard sizes are available in stock. Custom designs typically ship within 3–7 business days, depending on complexity.
Yes, immersion-type cartridge heaters are suitable for heating liquids and gases in tanks or closed systems.
Depending on the sheath and insulation, cartridge heaters can operate up to 750°C (1382°F).
Termination types include flexible wires, plug type, 90° L-bend with conduit, immersion, and custom configurations.
Wattage density is chosen based on the application type, required heating rate, material being heated, and space constraints.
Yes. With proper temperature control and installation, they are designed for continuous and reliable industrial use.
