Maumee, Ohio: Surface Combustion supplied two (2) new Allcase® Batch Integral Quench Furnaces to Cambridge Heat Treating of Cambridge, Ontario. Cambridge also purchased two (2) used Allcase furnaces in Ontario. All four (4) Allcase furnaces are installed in the same line, along with a previously purchased 30”x30”x48” Allcase with top cool which are all serviced by Surface’s charge car, Uni-DRAW® Batch Tempering Furnaces, washers, and RX® Endothermic Atmosphere Gas Generator.

Surface commissioned the new furnaces and continues to support the used equipment at its new home. The Allcase’s rugged design, ease of installation, and Surface’s aftermarket parts and service made this project a success. The 36”x48”x36” batch heat treat line greatly expands Cambridge’s capacity for carbonitriding, carburizing, neutral hardening, and added ferritic nitrocarburizing (FNC) and normalizing capacity with the atmosphere top cool chambers on the two (2) new Allcases.

Says owner Peter Robbins, “We could not be happier with our Surface purchases. Their robust equipment is built for longevity, and we appreciate that they are easy to operate and maintain. Surface’s Aftermarket parts department ensures that we always have the necessary parts for maintenance in a timely manner, and their customer service department is always available for a telephone or service call.”
