Chamber furnace

Our Hydrogen Bell Jar Furnace features a space-saving design and includes an electric actuator raising the chamber for easy and complete access to the loading area. Pneumatic locking clamps ensure a vacuum-tight seal isolating the chamber environment. A retort with an independent gas line keeps binders and volatile products from entering the hot zone, while at the same time improving temperature uniformity. The gas exit has a burn-off assembly for removal of hydrogen or other flammable gases. Specifications General Specifications Hot zone size of 8″ diameter x 10″ high (203 mm x 254 mm) Automated lift and clamp mechanism for bell jar chamber Hydrogen operation with integrated safeties Retort allows removal of volatile substances while improving thermal uniformity Space-saving design Details CHAMBER AND HOT ZONE The furnace chamber is cylindrical in shape and is manufactured from double-walled stainless steel. The chamber is welded and electro-polished for vacuum integrity and appearance. The whole chamber including shields and heating elements are lifted by an electric actuator to give full and easy access to the loading area. There are two instrumentation feed through ports (for thermocouples) and a gas-ported quartz sight window is provided for viewing. The hot zone is manufactured from tungsten and molybdenum, with multiple layers of shields to minimize heat loss. A molybdenum retort lifts up and down with the Bell Jar. The retort serves two purposes, it isolates and protects the hot zone from volatile process by-product, and it increases temperature uniformity of the heated zone.
