RX® Endothermic Atmosphere Gas Generators for Heat Treating

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[1] 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...

Allcase® is the industry standard for versatile, reliable, high production, controlled atmosphere heat treating.

Allcase® Batch Integral Quench Furnace processes hardening, annealing. Atmosphere of exothermic gas, endothermic gas, or nitrogen

Allcase® Batch Integral Quench Furnaces are installed around the world to heat treat a wide range of components from small fasteners to large, heavy castings. With continued advances in process control, energy efficiency and automation, the Allcase remains the most respected furnace in the industry.

Surface designed the first ever batch integral quench furnace – the Allcase – over 65 years ago.

Reliable, repeatable and rugged performance controls and automation available in 6 standard effective work sizes and 4 different configurations, an Allcase line can be fully automated with companion equipment to process loads from start to finish.

Allcase Batch Integral Quench Furnaces provide heat treaters value through greater process control, higher production and consistent results. The efficient gas heated units can be equipped with either bung mounted vertical “U” tubes or rear mounted horizontal Trident® tubes. Electrically heated units using Surface’s patented Proelectric®...
