High Cycle High Stress Cooling Water Products

In November 2003, ChemTreat was awarded an important US patent 6,645,384 titled, “Method for Inhibiting Scale In High Cycle Aqueous Systems.” This patent details a breakthrough in scale control technology, whereby cooling waters can be operated at much higher cycles or temperatures than previously obtainable with conventional technology. The key building block for these products is based on Quadrasperse^®.

Quadrasperse^® is ChemTreat's revolutionary new quad-polymer technology. Quadrasperse^® programs provide superior deposit control for calcium phosphate, calcium carbonate, magnesium silicate and iron. The Quadrasperse^® quad-polymer is thermally and hydrolytically stable making Quadrasperse^® the technology of choice for high stress and high cycle cooling water applications.

The ChemTreat PolyTrak^® Product Test Kit is another new technology recently developed by ChemTreat. The patented technology used by the kit enables cooling water and boiler inhibitor products to be easily measured in the field based on the level of active polymer. The PolyTrak^® kit allows ChemTreat field engineers and customers to effectively optimize treatment program dosage and performance.

Increasing regulatory issues at both the state and federal level are putting new demands on the types of chemicals which can be safely discharged to the environment. In response, in 2004, ChemTreat is introducing a new line of phosphate-free cooling water products. These products give excellent performance, but contribute zero phosphate to cooling tower discharge. Products in the CL-4600 series and are all zero phosphate cooling water treatments.

ChemTreat recently introduced a new range of closed loop corrosion inhibitors specifically designed for multi-metal systems, including aluminum. CL-2890 and CL-2891 are new, non-nitrite based corrosion inhibitors offering excellent corrosion inhibition for ferrous and cupric alloys, and also aluminum-based alloys. This unique chemistry is exclusive to ChemTreat and will provide long-term protection for multi-metal closed loop systems.

In response to a need from the food industry for condensate corrosion inhibitors that have indirect contact with food, ChemTreat has introduced BL-1560 and BL-1562, FDA approved non-amine condensate line treatments. These filming inhibitors offer excellent condensate line protection without the problems associated with filming amines such as gunking. The materials are FDA approved for indirect food contact, and ChemTreat is proud to announce we have developed a specific field test for these products which allows the engineer to test for and quantify the prescence of the corrosion inhibitor. Through the use of this test, product dosage can be carefully controlled to ensure both effectiveness and regulatory compliance.

Brine systems are frequently untreated because of poor availability of effective corrosion inhibitors. ChemTreat has extensive experience of treating calcium and sodium chloride brines, as well as lithium chloride brines. Several new brine inhibitor technology products were recently introduced including CL-2852 and CL-2888. These products are designed for effective corrosion inhibition of calcium chloride brines. Corrosion rates in brines treated with these inhibitors are typically less than 1 mpy on mild steel, and these treatments are becoming widely adopted by the chemical and pharmaceutical industries as the best approach to brine corrosion control.

ChemTreat is the first water treatment company to introduce a neutral pH Quadrasperse^® based on an iron cleaning program. The high stability and excellent surfactant characteristics of Quadarasperse made it an excellent candidate for on-line iron removal program. With neutral pH cleaners, effective iron removal can be achieved without the need for inhibited acids and the associated hazards of handling and disposing of such materials.

Many closed systems used in manufacturing industries have stringent low conductivity requirements (for example, in automotive and semi-conductor manufacturing). ChemTreat was able to address this need and has developed a new product, CL-2880, which provides excellent corrosion inhibition of both ferrous and copper-based alloys at conductivity levels approaching 100 μmhos. This product addresses an important market need where very few corrosion control alternatives previously existed. The product is environmentally friendly and is directly measurable using the PolyTrak^®test kit.
