Our large heat treat furnace contains a usable zone of 3 cubic feet (84l) and as our other heat treat furnaces, is capable of temperatures up to 2200°C. With an 800 lb (364 kg) load limit, it features a high load capacity. The unit shown here features a 16″ diffusion pumping system, and gas heat exchanger for rapid cooling. The hot zone features tungsten, molybdenum or tantalum mesh or rod heating elements, insuring excellent uniformity, longevity, and product compatibility. With its high load capacity and large size, this furnace is designed for production or processing large batches of product. The chamber is loaded from the front and contains a Hot Zone with a 14″ x 14″ x 28″ usable zone and a +/- 10°C temperature gradient. The heated zone consists of identical mesh or rod heating panels, providing four sided heating. The elements feature excellent uniformity and longevity. The furnace chamber is manufactured from double-walled stainless steel welded together and polished for a clean finish and good vacuum integrity. Chamber ports are incorporated for auxiliary equipment and sensors. The hot zone shields are mounted in a chamber frame, allowing for the thermal growth of the zone during the heat cycling. The furnace front door is hinged and water-cooled and provides full access to the loading area. The rear cover is removable for maintenance. The optional gas heat exchanger allows for quick-cooling down to room temperature. The furnace load is placed on the load support rails or hearth plate. The load supports are engineered to feature a high load capacity and a low thermal conductivity loss to the chamber walls.
