Product Description

Low Watt Density Cartridge Heaters

In low Watt density heaters sheath temperatures should not exceed 300oc. The Low Watt Density Cartridge Heaters design consists of helically wound resistance coil made from nickel-chrome wire or D- Wire, evenly stretched and strung through holes in a round ceramic or porcelain insulator. The element assembly is inserted into a Stainless Steel sheath. SS provides the best combination of physical strength and resistance to heat oxidation up to 300oc.
Specially selected magnesium oxide is used to fill all remaining space inside the ceramic or porcelain insulator to enhance dielectric strength, thermal conductivity, and offer longer functional heater life.
Porcelain or Ceramic Insulators are selected depending upon the temperature expected from the heater.
