5 important advantages Extended service saves time and money The Organic Acid Inhibitor Technology (OAT) in our Delo XLI cooling water treatment has a very low additive depletion rate, ensuring long-term corrosion protection under all operating conditions. There is no need for supplementary additive top-ups. Delo XLI cooling water treatment has an extended service life, with recommended maximum service intervals of 32,000 hours. Delo XLI cooling water treatment has an extended service life, with recommended maximum service intervals of 32,000 hours. Caring for the environment Delo XLI cooling water treatment is a water-based, low toxic, environmentally friendly, nitrite-free carboxylate inhibitor treatment. Minimized maintenance costs Delo XLI cooling water treatment has better heat exchange than conventional coolants. Our technology inhibitor system protects against wet liner cavitation erosion and provides exceptional protection to aluminum and cast iron surfaces under heat transfer conditions. outstanding at high temperatures Tests show Delo XLI cooling water treatment remains stable at high temperatures and does not form a film that can hinder heat transfer. OAT protects metal surfaces by physical absorption or by chemisorption only where needed, and does not impede heat transfer. The graph below shows that with Delo XLI OAT, heat dissipation is stable over time, while with conventional cooling water treatment heat dissipation may decrease due to build-up of insolation layers (oxides and/or inhibitor salts), leading to increased component thermal stress Engine Temperature C Conventional Tests show engine component temperatures stay stable with Delo XLI.

6 corrosion protection mechanism Corrosion is the combination of two processes, an oxidation-reduction of the metal surface and the electron flow from an anodic site to a cathodic site. Conventional products protect against corrosion by creating a protective layer over the complete metal surface, thus impeding heat transfer. Chevron s Delo XLI cooling water treatment protects against corrosion by electronically bonding with the anodic sites throughout the cooling system. This polarization process protects the metal surface against oxidationreduction. Because Delo XLI cooling water treatment bonds only with the anodic sites, additive depletion is minimal and heat transfer performance is not impeded, giving the product significant advantages. Industry approved The corrosion inhibitor technology (OAT) in Delo XLI has gained the approval of many major marine, heavy duty, automotive and stationary engine manufacturers, and is currently used in some of the world s most advanced engines.

7 easy, cost-effective monitoring Save time and money by monitoring your cooling water condition with onboard testing and FAST services. Below, left to right: Chevron s Portable Refractometer designed to measure % Brix, ph and chloride test strips. Refractometer testing The hand-held refractometer spot test is a quick method for determining the concentration of Delo XLI cooling water treatment in water. This method is easy to perform with Chevron s Portable Refractometer and does not require extensive sample handling or expensive equipment. Chloride and ph monitoring is easy Delo XLI s OAT corrosion inhibitor system is designed to protect aluminum and other system metals at lower ph levels than conventional coolants. Acid and base indicator strips are used to easily measure ph balance. High chloride levels can significantly increase the risk of corrosion, and are also evidence of seawater contamination in the system. For onboard testing, commercially available test strips can be used for quickly and conveniently measuring rough chloride levels in cooling water. Chevron recommends testing the Delo XLI cooling water treatment s concentration, ph value and chloride levels once a week. Comprehensive FAST reports Chevron s FAST service provides in-depth onshore analysis of your cooling water samples at advanced global laboratories. We report on several parameters and elements in your cooling water samples, as part of our comprehensive equipment monitoring program.
