Established in 1942, Eriez is a global leader in separation technologies. Our commitment to innovation has positioned us as a driving market force in several key technology areas, including magnetic separation, flotation, metal detection and material handling equipment. The company’s 900+ employees are dedicated to providing trusted technical solutions to the mining, food, recycling, packaging, aggregate and other processing industries. Headquartered in Erie, Pennsylvania, USA, Eriez designs, manufactures, and markets on six continents through 12 wholly owned international subsidiaries and an extensive sales representative network.
Eriez was founded by O.F. Merwin, a traveling grain milling equipment salesman, who repeatedly heard from his customers about the same issue: ferrous contamination in their processes. From tiny bits of wire to nails and bolts, to horseshoes and hammers, stray iron would flow down the chute with grain into the miller’s equipment, causing serious damage to their machinery and potentially causing an explosive fire.
O.F. Merwin developed the first permanent magnetic plate separator prototype in the basement of his Erie, Pennsylvania home to protect grain millers from their ever-present issues, and through Bob and Betty Merwin’s continued strategic expansions and unrelenting forward-thinking, the rest is history.
The Merwin Family’s legacy of innovation continues today, with Richard Merwin continuing to serve as Chairman of the Board.
