The Brew Division of Thermal Technology has recently designed and manufactured a very high vacuum / hydrogen
furnace for heat treating and brazing applications. Our customer needed specialty features
such as 1.0 x 10-7 torr vacuum at 1400° C, computer
controls and a hot water system to minimize condensation.
This horizontal furnace system has full opening front and rear doors
and a usable heated area of 36" wide by 30" high by 48" deep. The hot zone
has molybdenum heating elements on all six sides. Each of the six heater arrays has
independent power control which allows the furnace to be tuned to provide ± 5° C temperature uniformity or better
depending upon the thermal load and processing parameters.
The furnace was supplied with a 35" diffusion pumped vacuum
system, liquid nitrogen cold trap and automatic switch-over Dewar station. The furnace is
also capable of operating in hydrogen atmosphere (wet or dry) to 1100°
C. Since safety is always of primary concern, multiple safety features were incorporated
into the furnace design. The furnace is equipped with explosion-proof valving, primary and
secondary pressure relief ports, a dual ignitor burn-off tower and a residual gas
analyzer. Other features include controls with uninterruptible power supplies, mass flow
gas controller and recirculating gas cooling system. |

A close working relationship with our customer enabled us to gain a
solid understanding of their processes which in turn enabled us to offer a furnace system
that will give them a competitive edge in their marketplace. We enthusiastically await the
opportunity to work with customers and to meet the serious demands of their high
temperature processes.
Thermal Technology will be in Booth No. 863 at the upcoming ASM Heat Treating Exposition, October 12 - 15, 1998 in
Rosemont, Illinois. Please stop by to discuss your furnace requirements. If you cannot
make it to the show, contact us for more information on our full line of Brew
and Astro furnace systems.
