Heat Treating & Heat   Processing
1800 & 2500°F operation at 10-5 to 10-6 torr.
Inert gas purging and forced cooling at 1 & 2 Bar.
Low out-gassing, all metallic hot zone for clean high vacuum.
Cold wall, 2 door, front loaded, batch type vacuum furnace with polished stainless steel interior.
Water cooled baffle and valve - prevent back streaming.
Durable molybdenum lanthanum oxide alloy hot zone. 
Proprietary ‘’BAR’’ element shape for radiant energy distribution and improved rigidity to resist sagging. 
Hot zone rolls out for easy cleaning. 
Unique multiple trim zone arrangement completely surrounds work and automatically compensates vertically and horizontally for uneven thermal characteristics of work loads. 
Low hot zone mass for fast heat up and cool down. 
Reduces distortion of work and accelerates cool down with programmable temperature modulated dual channel inert gas cooling system that is valved off from chamber. 
Automatic operation, including start-up from cold and auto sequence shutdown.



VHT furnace hot zone easily rolls in or out of the chamber on permanent tracks inside the chamber and temporary tracks on the outside.
