Tubular cartridge heater ULTRAMAX

CARTRIDGE HEATERS WITH THERMOCOUPLE ULTRAMAX High power density cartridge heaters with thermocouple permit to use high Watt charges in really concentrated spaces, guaranteeing a high reliability also in heavy working conditions. The technology used for their production makes the difference in comparison with other cartridge heaters. The nickel chromium wire is wrapped on magnesium oxide, near the metallic sheath, with a really thin insulating wall and highly pressed, obtaining a good thermal exchange which maintains the temperature of the resistive wire to a lower value in comparison with other heaters where the wire is in a deeper position inside adequately pierced tubes. The thermocouple is “J” type, Iron/Constantan, with red/blue wire, with a temperature range of -20 +750°C and it is positioned with insulated joint in the proximity of the bottom disc.
