GRAVER TECHNOLOGIES, INC

Graver Technologies

Graver Technologies boasts a long history of providing innovative technology based products and excellent customer service.  The company was founded in 1866 by William Graver in Lima, Ohio.  In the early days the product focus was a hot process softener used as a demineralizer for steam locomotives. During the 140+ years to the present, the company expanded into industrial and commercial markets with diverse products that included reverse osmosis water treatment systems, condensate polishing systems for power generation applications, residential water treatment and softening and even transportation.

It was in 1981 that Marmon Industrial Corporation, a privately held corporation run by the Pritzker family, bought the combined companies, and in 1993 Graver’s corporate headquarters were moved to Glasgow, Delaware, where it remains today.

Graver Technologies has four major divisions:

  • Utilities Group - Ion Exchange Resins and Condensate Filter Elements
  • Liquid Filter Products Group – Liquid Filters & Filtration Products
  • Industrial Filter Products Group – Air & Gas Filters and Systems
  • Adsorbent Products Group – Carbon & Adsorbent Product

The latest chapter in Graver’s history occurred in March of 2008, when Berkshire Hathaway acquired 60% of the Marmon Group from the Pritzker Family.  Under the new corporate ownership, Graver continues to thrive and grow by increasing sales directly to the power generation and process filtration markets, and through a series of acquisitions that has created a product portfolio that addresses applications in a wide range of markets.

Graver Technologies is headquartered in Glasgow, Delaware and has manufacturing and marketing facilities in Newark, New Jersey, and Honeoye Falls, New York.
