Cartridge, infrared, ceramic heaters,
 
Infrared heater: These heaters are special radiative heaters emitting external surface; its backside reflector adds up uniformity of heat and is available in single or twin tube arrangements. An additional reflector can also be arranged with these heaters.
 
Cast in heaters: The specialty of our method is that it produces a casting free of internal voids and consequently drastically reduces porosity, resulting in smoother as cast surfaces as essential for good thermal conductivity providing long life and dependable trouble-free services.
 
Cartridge heaters: The speciality of our method is that it produces a casting free of internal voids and consequently drastically reduces porosity, resulting in smoother as cast surfaces as essential for good thermal conductivity providing long life and dependable trouble-free services.
 
Ceramic insulated band heaters: The electric resistance element is a spiraled nickel-chromium (80:20) wire mounted in articulating specially designed ceramic supports forming a flexible mat. This mat is mounted in a stainless steel shell with 3 mm thick heat insulation. The webs of this channel shell are fluted in a manner that allows it and the heating mat to flex readily to any radius. The band is fastened by lock-up flanges integral with the shell. The heater is particularly recommended where temperature in excess of 800° F in plastic machine assemblies, such as heater cylinders.
