United 313 is a blend of organic penetrants and dispersal agents for use in cooling water systems. It functions by penetrating the matrix of organic deposits, which results in the sloughing off and dispersal of the organic matter. This product is Earth Smart® Certified; formulated to be safer in use for both the user and the environment. When used as part of a complete United Laboratories’ Cycle Smart® cooling tower treatment program, it minimizes environmental impact and keeps your cooling system operating cleanly and efficiently.
