Low Density Catridge Heater

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.
