Product Description
The Dresser-Clark HRA series was a large slow-speed integral gas engine-compressor built for U.S. interstate natural gas pipeline mainline compressor service from the 1950s into the 1970s, continuing the Clark Brothers pipeline product line under Dresser Industries. According to publicly filed asbestos litigation records, HRA units were allegedly insulated with asbestos-containing cloth lagging on the power-cylinder jackets, and allegedly used asbestos exhaust manifold gaskets and allegedly asbestos rope packing around the cylinder heads and access covers.
