LOW CHARGE CARTRIDGE HEATERS
The cartridge heater CLD( low density) (up to 5 watts / cm2), is a conventional heating element, usually when working conditions are not particularly severe. In the LD Resistors, Coil nickel-chromium is contained within a base ceramic mass is surrounded with magnesium-oxide powder, which also fills all the internal spaces of the insulator core.
