Sioux was founded in 1939 in Beresford, South Dakota, initially manufacturing steam cleaners used to clean automobile engines. In 1965, the company was sold to John and Virginia Finger, who began designing additional models of steam cleaners and hot or cold water pressure washers, with larger capacities and pressures for application in other industries. Sioux distributorships were established throughout the USA and in other countries.
In the early 1960’s, Sioux built its first instantaneous water heater for a concrete batch plant, which Sioux developed into another product line. Over the next 50 years Sioux continually expanded and improved these units to provide numerous features specifically for application in concrete production, establishing the reputation as the number one recognized brand in the USA. Sioux added discharge and circulation pumps, water storage tanks, and control systems designed for ready-mix and precast plants. This product line was further modified and developed into another product line, the Solution Heater, which is used in the mining of precious minerals. Sioux now has approximately four thousand units in service in the concrete and mining industries throughout North and South America. Historical Photo
Starting in 1960, Sioux developed the finest commercially-viable line of electrically-heated steam cleaners and hot water pressure washers. These units are similar to conventional hot water washers or steam cleaners, except the oil or gas burner used to heat the water is replaced by electric resistance heating elements enclosed in a vessel. Sioux offers both standard and explosion-proof models, third-party certified to UL, CSA, and NEC codes and standards. For decades Sioux has been recognized as the world leader in this product line, and offers custom packages used in offshore oil exploration and production, surface and underground mining, nuclear power plants, chemical and pharmaceutical manufacturing, refineries, waste water treatment plants, manufacturing facilities, and in numerous other applications.
On November 30, 1967 a fire burned the original Sioux building to the ground, and the decision was made to rebuild. That May, Sioux began manufacturing from a new, modern facility in the same community. In 1989, Virginia Finger assumed the Presidency of Sioux, and John Finger became Chairman of the Board.
In April of 1995, John “Jack” Finger (John and Virginia’s son), a registered engineer with degrees in electrical and mechanical engineering, returned to work at Sioux, after 21 years’ experience as a sales engineer and district manager in California, and in project design engineering and construction management in Nevada. During this time, Sioux began to value engineer product lines, providing increased performance and customer value at lower cost, meeting numerous safety codes and standards, and offering options and features required for unique applications.
In 2008, Sioux Corporation established the only national agreement with Carrier Corporation to offer Carrier water chilling systems for use in hot-weather concrete production. Sioux now offers entire water heating and chilling systems engineered and fabricated specifically for use in ready-mix concrete production or precast concrete production.
On January 1, 2018 the Finger family sold the company to three Sioux managers: Meg Andersen, Eric Hansen, and Brad Hryonimus. Upon completion of the sale, Jack Finger retired after multiple decades of service with Sioux. Brad Hyronimus was named President and CEO.
Today, Sioux has a modern 50,000 square foot manufacturing plant and office facility on a 15-acre site in Beresford, South Dakota.
