Our History

Graver Technologies boasts a long history of providing innovative technology based products and excellent customer service. The company was founded in 1866 in Lima, Ohio and in those early days, the product focus was a hot process softener used as a demineralizer for steam locomotives. 

Graver then expanded into two markets: industrial and commercial, each 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.

In 1981 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.
