Able Distributors (Chicago) hosted a boiler water seminar at the Environmental Technical Institute in Itasca, Ill., March 22. The seminar titled, “Are you guilty of the cast-iron mentality?” addressed the importance of testing the water in today's high-efficiency boiler systems made with aluminum heat exchangers rather than traditional cast iron construction. “Hot Rod” Bob Rohr (pictured), president of the Radiant Panel Association; Drew Longnecker, division manager/Engineered Fluids of The Noble Co.; George Hunt, hydronics director of Rhomar Water Management; and Mike Dwyer, of Weil-McLain, presented at the seminar. Able, based in an ethnically diverse neighborhood in Chicago, also hosts seminars for contractors in Spanish and Polish.
