The GTH is a hot wall tube furnace capable of low furnace temperatures and ultra-high vacuum levels.  Units are comprised of a rolled alloy tube typically stainless, surrounded by either quartz or a ceramic fiber tube furnace.  


Applications typically include annealing, heat treating, and thermal shock testing.  The Model GTH features full atmospheric control and is typically operated in the medium or high vacuum ranges.   


Full system integration can be provided which includes but is not limited to, roughing & high vacuum pumping systems, atmospheric sweeping, gas blending backfill, and fluid cooling systems.
