Renderer and biodiesel producer Sanimax is building out production capacity at its 20 MMgy manufacturing facility in DeForest, Wis., and has chosen Apache Stainless Equipment Corp. to provide stainless steel tanks to support the build-out. Apache supported Sanimax’s need for increased capacity by supplying an atmospheric stainless tank and three pressure vessels within the past month. Sanimax would not disclose how much additional production capacity the DeForest plant was installing.

The most recent tank supplied by Apache was used for fuel storage. The tank was constructed from stainless steel with exterior insulation and aluminum cladding. The tank increased storage capacity for Sanimax by 30,000 gallons. The 132-inch diameter, 45 ft. high and 19,000 lb. atmospheric tank was API 650 rated. Apache provided in-house insulation and aluminum cladding of the tank and was shipped via Apache truck. Apache serves the biofuel industry with many types of specialized tanks, including distillation columns, evaporators, ASME vessels, API-650 vessels, clad vessels, custom mix tanks and storage tanks. The Apache facility in Beaver Dam, Wis., is fully equipped for shearing, forming, welding, rolling and in-house head making. The company also provides finishing capabilities, including automated mechanical polishing, electropolishing and passivation. Another Apache facility in Plover, Wis., produces carbon steel tanks and equipment. Apache is an employee-owned company and a subsidiary of Dexter Apache Holdings Inc.
