Graver Technologies

What Graver Technologies does

Graver Technologies designs, develops, and manufactures products for purification, separation, and process filtration, serving industrial process industries where contamination control is mission-critical. Founded in 1866 in Lima, Ohio as a producer of hot process softeners used as demineralizers for steam locomotives, the company has evolved over more than 150 years into a diversified industrial filtration specialist, operating from its headquarters at 200 Lake Drive, Glasgow, Delaware, USA, with 51–100 employees, 82+ technology patents, and a presence in 120+ countries supported by 400+ facilities worldwide. The business is organized into three units — Adsorbent Products (Ecosorb®, MetSorb®), Filtration & Separation (ZTEC™, Stratum™, MBC™, CelluTEC®, TefTEC™, Scepter® tubular crossflow, TECpore™ PES membranes, and air & gas filtration systems), and Power Generation (Gravex®, Powdex®, Radex®, Ecodex®, Ecocote®, Nanodex™, and condensate polishing septa such as Aegis®, DualGuard®, AFA®, TurboGuard®) — addressing applications where product failure is not an option.

The technology stack is anchored in proprietary adsorbent media and membrane chemistry, including MetSorb® for heavy metal removal (arsenic, lead, uranium, antimony), TECpore™ polyethersulfone membranes, and Scepter® tubular crossflow membranes. Target applications span nuclear and fossil power plant condensate polishing, semiconductor ultrapure water and chemicals, biopharmaceutical and medical-device sterilization, municipal drinking water compliance, food and beverage clarification, and broad industrial process filtration. Pricing is not publicly disclosed and is set via custom sales-engineering consultation.

Graver is a privately held subsidiary of Marmon Holdings, Inc., part of Berkshire Hathaway, and operates as a member of the Marmon Water group alongside affiliated partner companies (Enersul, Filtrex Technologies, KX Technologies, Marmon Industrial Water, Ecowater Systems). Go-to-market combines direct enterprise field sales with an authorized distributor network (including a dedicated distributor portal) and active participation in industry events and associations (WQA, AWWA, WaterReuse Association, SPRI). Customer segments are horizontally distributed across Power Generation, Water Treatment, Healthcare, Air & Gas, Food & Beverage, Microelectronics, and Industrial, with no single dominant vertical disclosed.
