Mammoth, Inc. has a 75-year history of building innovative, quality products and satisfying customers throughout the world. Originated in 1935 as the Brown Sheet Iron and Steel Company in St. Louis Park, Minnesota, the company manufactured industrial gravity-flow and forced-air furnaces for both commercial and residential applications.
From this modest beginning, the company experienced an explosive expansion during World War II, when Brown became a major supplier of large industrial furnaces. Seeing the increasing market potential in the commercial and industrial sector, a small group of investors bought the company in 1953 and chose to focus on those lines. As the largest supplier of the largest product on the market, the company was renamed the Mammoth Furnace Company.
In 1965, the growing company became the Mammoth Division of Lear Siegler, Inc. It acquired a heat-pump manufacturing company in Holland, Michigan, and a coil manufacturing plant in New Germany, Minnesota. The St. Louis Park facility was expanded to keep pace with growing manufacturing requirements. After 29 years in the western suburbs of Minneapolis, in 1995, Mammoth headed south to a new facility in Chaska, Minnesota.
In addition to its namesake brand, Mammoth also owns the WEBCO brand. Founded in 1977 by Mr. William Eugene Bennet (retired), in Springfield, MO, WEBCO was licensed by The Wing Company to sell and fabricate Wing's rooftop energy recovery packages. Today, the WEBCO brand is recognized for custom air conditioning equipment that provides innovative, cost-effective solutions for some of today's most challenging air conditioning and air quality applications in critical environments such as automotive manufacturing, pharmaceuticals, bio-tech, food processing, and air terminals.
Today, Mammoth is a subsidiary of CES Group, LLC, the largest manufacturer and marketer of custom HVAC systems in North America. Manufacturing for chillers, chiller plants, custom packaged DX and replacement rooftop systems has moved from Chaska, MN, to Springfield, MO, and co-located with manufacturing for WEBCO brand products. Heat pump and vertical self-contained manufacturing remains in Holland, MI. Headquarters for Mammoth, including executive management and engineering, has moved from Chaska, MN to Eden Prairie, MN.
While its name and location have changed, the Mammoth brand continues to stand for leadership in quality, custom-built HVAC equipment. For more information on how we can design a custom solution for you, please contact your local representative.
