Monitrol 1301 corrosion and deposit inhibitor is a highly concentrated blend of corrosion inhibitors, phosphonates, surface active agents, and polymeric dispersants blended specifically to prevent scale, corrosion, and deposits in larger, difficult-to-treat cooling tower systems. When used with the Monitrol Cooling Water Management Program, the concentration of Monitrol 1301 can be automatically fed and controlled within a tight specification range, ensuring proper dosage and preventing costly overfeed of chemistry.
