Bodycote Thermal Processing purchased an AFC-Holcroft E-Z Series 13,500-cfh endothermic generator for installation at its Fort Wayne, Ind., plant. The modular design of the E-Z Series generator enables multiple units to be integrated for higher-capacity atmosphere generation. In this case, an array of three 4,500-cfh systems are integrated together to provide the needed capacity while requiring less floor space than three stand-alone units. The atmosphere produced by the E-Z Series generator, when enriched with natural gas, is suitable for gas carburizing and carbon restoration of the low- and medium-carbon steels. The addition of ammonia to the atmosphere will create a suitable atmosphere for carbonitriding. The atmosphere, as generated, may be used for clean annealing, normalizing and hardening of all carbon steels.
