CW409 Cooling Tower Treatment

Product Description

  • Concentrated: 7.5 ounces treats 1000 gallons of cooling tower makeup water at 3-cycles of mineral concentration.
  • Can be tested in less than 30-seconds with a simple test kit.
  • Contains a powerful blend of organic phosphonates with polymeric dispersants/crystal modifying compounds for control of scale in cooling systems with extreme hard and alkaline water without the use of acid. 
  • Contains a dual polymeric dispersing system for calcium carbonate, sulfates, iron and dirt particles. This chemical will help keep the cooling system cleaner and will aid in removing old scale that may have developed in the cooling tower.
  • Utilizes a robust and resilient filming corrosion protector chemical that helps reduce iron and mild steel corrosion.
  • Has added copper/brass corrosion inhibitors that are resistant to oxidizing chemicals such as chlorine and bromine.

CW409 Application Rate and Control Parameters

  • CW409 is intended for use in re-circulating cooling systems and cooling towers to control scale and corrosion.
  • Use O.P. Test Kit P.N.#CNPK158 to test CW-409. The recommended test range is 10 - 20 total drops. If the test results are high or low, see Cannon Water Technology Inc.'s "What To Do If Test Results Are Out Of Range".
  • CW409 contains no heavy metals or restricted ingredients and water treated with CW409 can be discharged to sanitary sewer. Avoid discharging any cooling tower water to storm drains or open bodies of water.
  • Oxidizing biocides such as chlorine and bromine can be used in systems treated with CW409 so long as the concentration of chlorine or bromine does not exceed 3 ppm.
  • CW409 is compatible with all non-oxidizing biocides with the exception of cationic quaternary ammonium compounds.
  • CW409 can be shipped UPS in 5 gallon containers.  Larger sizes shipped by common carrier.
