The XLC Series Atmosphere Retort Furnaces represent an advanced design which emphasizes process quality and control as well as operator safety. The control system, alloy retort and flow system are completely integrated as one unified system. Any application requiring 100% hydrogen or a mix of hydrogen, carbon monoxide, natural gas or any other combustible atmosphere (as well as any purely inert atmospheres) may be used in the XLC Series. Hydrogen brazing and stainless steel annealing are typical examples. Any batch process that can not tolerate oxygen or that requires a high degree of atmosphere reliability, Repeatability and low dew point is a candidate for this furnace. Maximum temperature is 2200°F (1200°C) although lower maximum temperatures are recommended for long retort life. Depending on the purity of the gas used these furnaces can maintain a dew point as low as -60°F.
