According to the results from new performance testing conducted by The Pennsylvania State University (Penn State), the Eriez Xtreme RE7 Tube Circuit is significantly stronger than any other magnet on the market today. Full test data is available from Eriez.

Eriez commissioned Penn State to determine which commercial tube magnet most effectively removes dangerous ferrous metal and weakly magnetic contaminants from process flows. Thirteen tube magnets from various suppliers were stripped of brand identity and then provided to Penn State, the Behrend College, for testing.

According to conclusions noted by Penn State, the pull force of the Eriez Xtreme RE7 Tube Circuit was substantially stronger than any of the other samples. Eriez’ magnet was also among the best performers in terms of magnetic flux density.

The Eriez Xtreme RE7 magnet circuit, introduced in 2015, is available in all Eriez Tubes, Grates and Liquid Line Traps used in food, plastics, pharmaceutical, mining, foundry, chemical and other applications. “The increased power of the Xtreme RE7 has a direct and positive impact on product purity and plant productivity,” says Eric Confer, Product Manager-Magnetic Separation. “Customers benefit from the increased strength of the new Xtreme RE7 products without any additional cost over our previous Rare Earth products."
