Pit furnace is designed with a maximum operating temperature of 1750°F (954°C) and gross workload of 1600 lb. Temperature uniformity of ± 25°F at 1650°F (899°C) was documented with a nine-point profile test. The furnace can accommodate a work basket with a 25” diameter and 48” deep, providing a work volume of 13.64 ft3. A retort minimizes atmosphere consumption and furnace conditioning time between loads. The cover lid utilizes an electrically operated boom lift to ease loading and unloading. An upper furnace fence guard is intended to improve safety. The pit furnace is designed with the capability to use Homocarb fluid for the furnace atmosphere. The Homocarb FLUID ATMOSPHERE system pumps the fluid through a furnace inlet tube to a heated target suspended from the cover inside the furnace chamber. This ensures that the fluid is dissociated to create the furnace atmosphere before it comes into contact with the customer workload. The furnace also is designed with a forced cooling system that accelerates cooling of the load while still under a protective atmosphere.
