Patterson filed for Chapter 11 bankruptcy. In December 2016, the Carrier Process Equipment Group (CPEG), a joint venture of Carrier Vibrating Equipment Inc. and S. Howes LLC purchased Heyl & Patterson's Renneburg Division for thermal processing. The Bulk Transfer division was purchased by Hall Industries, and now operates as Heyl & Patterson Equipment. The Heyl & Patterson Equipment headquarters is located in Canonsburg, Pennsylvania, with manufacturing facilities in Ellwood City & Grove City, Pennsylvania. Heyl & Patterson Divisions Bulk Transfer Division Heyl & Patterson Equipment designs and manufactures variations of rotary railcar dumpers, or "wagon tipplers," which are in operation worldwide. These include rotary dumpers, C-shaped rotary (CR) dumpers, closed and open-sided turnover dumpers, and single and multiple car dumpers. They also design and manufacture rail car moving devices such as train positioners, train indexing equipment, CUB and other support equipment. Bulk Transfer also offers material handling equipment such as barge unloaders with both grab and continuous bucket designs, and related specialty machinery. Renneburg Division Originally formed as the Process Division in 1955, it was renamed after the acquisition of Edw. Renneburg & Sons Co. of Baltimore, Maryland in 1985. Renneburg & Sons was founded in 1874, and was a world leader in process equipment. The Renneburg Division handles thermal processing of powders and bulk solids, as well as advanced chemical, mineral and environmental processing equipment, including fluid bed dryers and coolers, rotary dryers and coolers, calciners, agglomerators, presses and mixers. The division produces thermal processing technology that is environmentally sensitive and production-minded, tailored to the needs of the powder and bulk solids, chemical, and mineral thermal processing industries. Aftermarket Division Originally a separate entity known as HeylPat Technologies since 1996, the Aftermarket Division was consolidated into Heyl & Patterson in 2009. This division offers replacement parts and upgrades for both of the other divisions, whether products had been manufactured by Heyl & Patterson or other manufacturers. Their field engineers provide onsite mechanical, structural and electrical inspections, and complete engineering studies after an inspection can compare current operating realities with the original design of the equipment. DryFining In 2010, Heyl & Patterson was part of a team to be awarded with Power Engineering magazine’s 2010 Coal-Fired Project of the Year. The project, “DryFining,” created a new technology for coal-firing power plants that improves fuel quality, decreases volatile gas emissions, and reduces a plant’s operating expenses and maintenance costs.
