Over 200 years of combined experience. Serving the Midwest Since 1950.

Regionally focused service and support with over 150 combined years of water treatment expertise. Family owned and based in Saint Louis, Missouri since 1950.

We are also professional members of the Cooling Water Institute, the American Chemical Society and the National Association of Corrosion Engineers. Our technical service group is highly trained with no less than 400 field and classroom hours of training before ever going into the field. Each member of the service group participates in 24 hours of continuing training every year so that we can keep ahead of the curve. We manufacture all of our treatment blends in our own facility. This means we have control over the raw material selection, specialized chemistry use and the overall product quality. Every treatment chemical we use or sell is rigorously tested before it is put to market, and each batch is tested for consistent product quality. Don't buy chemicals, Buy Results. Results like extended equipment life maximized energy efficiency, maximized heat transfer and Scale-Free Heat Exchangers. Possibly the most important part of any of our Total Treatment Programs is our pledge that your open systems will be free of scale and biological fouling while under our care or we will chemical and/or mechanically clean your system free of charge. Scale Free results are guaranteed in writing in your service agreement. NO ONE ELSE OFFERS GUARANTEED RESULTS. No one.
