  • Elements are designed for maximum: Watt density, temperature, heat transfer, and heater life.
  • The useful life of a cartridge heating element is determined by how quickly the heat generated in the resistance wire can be dissipated to the outside sheath.
  • With low and moderate watt density elements, such as Hotwatt’s standard line, the conventional method of inserting helical coils in formed ceramics is an entirely satisfactory method of construction because the wire temperature relative to sheath temperature even though considerably higher, is still well within safe long-life operating temperatures

Low Density Catridge Heater

DIGIQUAL’S Low Density Catridge Heaters are made of helically wound nickel chrome resistance wire evenly stretched and placed in ceramic insulators. The elment assembly is inserted into Brass/SS 304 tube. High grade MgO powder is filled in the remaining space inside the ceramic insulators to increase thermal conductivity, dielectric strength and heater life.

  • Low watt density heaters are available in brass or SS 304 sheath.
  • Medium & High watt density heaters are available in SS 304 sheath.
  • Braided Wire, straight or right angle exit.
  • Uniform surface temperatures.
  • Flange type optional Braided wire.

Split Type Catridge Heater

split Type Catridge Heater
DIGIQUAL’S Split Type Cartridge Heaters are developed for high temperature application. Helically wound resistance coli is placed inside the tube filled with MgO powder and compacted for faster and efficient heat transfer

Ceramic Catridge Heater
