Designed for hot press metal forming applications, the Maxi-Zone High Temperature Insertion Heater produces continuous sheath temperatures to 2000°F/1095°C. An Inconel 600 sheath allows efficient operation at extreme temperatures. Because of this capability, many applications will observe considerable performance improvements with the Maxi-Zone versus other heat sources.
A unique feature of the Maxi-Zone is to provide two or three independently controllable areas along the sheath length. Precise temperatures can be produced in every location by arranging the process in multiple zones and monitoring and controlling each separately.
The Maxi-Zone’s primary heat transfer method is by radiation. The continuing oxidation of the sheath and inside walls of the hole at these temperatures produce excellent transfer of heat. This emissivity improves with usage, allowing sheath and process temperatures to be nearly identical. Diameters are substantially undersized versus standard cartridge heater applications. A .935″ diameter Maxi-Zone would be applied in a 1″ or larger hole. A Maxi-Zone is easily removed and replaced. Standard Maxi-Zone diameters are .495″, .685″ and .935″ with lengths from 18 inches to 15 feet. .210″ diameter Inconel 600 sheath tubular heaters are available for heating ceramic presses in similar applications.
