Stress Tolerant Azole
Corrosion of the copper alloys in your cooling system can result in failures of exchangers and can also lead to galvanic attack and an increase in pitting corrosion of your carbon steel assets. Ammonia, chlorides and other deleterious ions all represent high stress to your copper alloys. Conventional copper alloy corrosion inhibitors may work adequately under normal stress conditions but usually fail under high stress conditions such as when oxidizing biocide levels are high. Our Stress Tolerant Azole (STA) was formulated to overcome performance limitations by providing a very robust, long-lasting film to protect copper alloys even under the most demanding conditions.

Dual Cathodic Inhibitor (DCI)
Pitting corrosion is especially damaging to the metals found in cooling systems as it can result in rapid failure of your heat exchanger assets. Our Dual Cathodic Inhibitor (DCI) was designed to provide superior protection against pitting corrosion. By blending two proven cathodic inhibitors into a single product, DCI ensures complete suppression of the driving forces that cause pits to form.

High Charge Polymer (HCP)
Deposit and scale control is a critical component of any cooling water program. Nalco Champion has developed the most advanced deposit and scale control chemistry available in the industry today. Our High Charge Polymer (HCP) works to keep phosphate- and zinc-based corrosion inhibition chemistries soluble and corrosion levels low, even under the most demanding conditions. HCP chemistry benefits systems with high aluminum carryover from your pretreatment system or high iron from well water. We have seen improved performance even with increasing cycles of concentration. This translates to significant reductions in water usage where other solutions have failed.
