PROCESS CONTROL
VACUUM BAKE-OUT
A superior vacuum bake-out process within laboratory, research, and development operations
Application
With many laboratory or research & development tests, it is
critical that materials are free of gasses, water vapor, and
other contaminants. A vacuum bake-out is a process used to
remove such contaminants. Applying surface heat (normally
up to 392 °F (200˚C)) is required to successfully complete a
vacuum bake-out process. The removal of impurities allows
vacuum-baked components to be used in ultra-high vacuum or
ultra-high purity systems without fear of contamination. Heat is
used to help release impurities and other contaminants, from
components in a closed system (vacuum chamber), while a
vacuum pump removes those impurities.
Solution
Custom cloth heating jackets are ideal heaters for vacuum bake-
out applications. They fit around the outside of vacuum chambers
to provide the necessary heat. Vacuum chambers come in
many different sizes and shapes, often with complex shapes and
multiple exterior surface obstructions. Custom cloth heating
jackets can be designed and manufactured to fit almost any size
and configuration, ensuring intimate surface contact for consistent
heat across the entire heated area. The built-in insulation
maximizes efficiency, and reduces heat-loss, allowing them to
safely operate at several hundred degrees at very tight tolerances.
High temperature Samox ® or PTFE cloth construction provides
extreme durability and long service life under high temperature
uses. The heating element is BriskHeat’s patented multi-stranded
heating element. Several closure options are available to suit your
needs such as hook-and-loop closure (pictured), lace and boot
hooks, lace and grommets, or belts with D-Rings, making them
easy to install and easy to remove.
Further customization of cloth heating jacket includes:
• Redundant circuits to act as back up if the primary element fails
• Non-ferrous components for research and experimentation that
include magnetic fileds
• View ports to observe the chamber’s interior during an
experiment
A total solution for using cloth heating jackets includes choosing
the right temperature control system. SDX,
or the MPC2
Multipoint Temperature Control Panel are designed to provide
control needed for vacuum bake-out. The amperage load, heater
configuration and environment will determine the best solution for
your application.

For laboratory or R&D experiments necessitating high
wattage and very high temperatures, Mineral Insulated (MI) is
recommended. MI cable is semi-rigid and electrically insulated
using Magnesium Oxide (mineral) to ensure safe electrical
insulation with maximum thermal transfer. MI cable has
maximum exposure temperature of 1832°F (1000°C) and a
76.2 W/ft (250 W/m) watt density.

Apart from vacuum bake out, cloth heating jackets are also
superb heaters for research projects involving systems with
complex structures. Custom heaters can be made to fit all sizes
and shapes of equipment such as tanks, pipes/tubes, joints,
valves, and much more.
