Surface® Combustion RX® Endothermic Atmosphere Gas Generators provide onsite generation of endothermic gas for controlled atmosphere furnaces performing metallurgical heat treatments such as carburizing, carbonitriding, ferritic nitrocarburizing (FNC), hardening, and annealing. Industries using RX gas include Automotive, Energy, Mining, Agricultural, and Commercial Heat Treating.
Surface Combustion pioneered the development of RX gas to be used as the atmosphere for modern gas carburizing. RX gas is produced by converting the incoming supply of natural gas and air by catalyst and heat to a composition of 40% N2, 40% H2, and 20% CO. The RX gas generator’s reliable production of consistent atmosphere chemistry with low oxidation, decarburization and soot potential revolutionized the heat-treating industry by enabling boost/diffuse carburizing, as well as atmosphere carbon control.
Our standard modular RX generator designs range from one (1) to five (5) tubes. Surface offers short and tall tube designs. Depending on the height...Read More >
