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.

The diagram
illustrates a nine zone platen with six, three zone
Maxi-Zone Insertion Heaters. Each zone can be sensed and
controlled individually. A platen with 6 elements can be
designed with 6 zones utilizing a Maxi-Zone with 2
independent zones. For even more precise control, the platen
can be comprised of even more zones, depending upon what's
practical.
