Manufacturer's description

Cat ELI (Extended Life Inhibitor) Corrosion Inhibitor Concentrate is formulated for marine and industrial engines operating in environments that do not experience freezing temperatures — it does not provide freeze protection. Unlike conventional coolants, it contains no glycol, which simplifies coolant changes by reducing residue buildup. Cat ELI uses organic additives that target only the areas of the cooling system susceptible to corrosion, helping maintain the integrity of engine components and showing strong effectiveness in protecting aluminum parts common in modern diesel engines. This active-protection approach lets Cat ELI last three to six times longer than conventional coolants and supplemental coolant additives (SCA), with fewer coolant checks, inhibitor replacements and system flushes when used with Cat filters and regular S•O•S fluid analysis. Typical service life is up to 3,000 hours between SCA additions, or up to 12,000 hours (6 years) with a one-time addition of Cat ELC Extender at 6,000 hours. Typical characteristics: red color, recommended dilution 7.5%, pH (7.5% solution) 8.5, boiling protection 100°C at sea level / 121°C with a 1 bar (15 psi) cap. It exceeds automotive and heavy-duty coolant performance requirements per ASTM D3306, D4985 and D6210 (ASTM D1384, D2570, D4340 performance requirements). Distributed in Romania by Bergerat Monnoyeur.

Applications

• Formulated for marine and industrial engines operating in environments that do not experience freezing temperatures.

Performance & benefits

• Uses organic additives that target areas prone to corrosion, helping maintain the integrity of engine components.
• Can last three to six times longer than conventional coolants, potentially reducing how often coolant is checked, inhibitors replaced and the system flushed.
• This is achieved when used with Cat filters and regular S•O•SSM fluid analysis.
• Shown to be effective at protecting aluminum parts, common in modern diesel engines and cooling systems.
• Contains no glycol, simplifying coolant changes by reducing residue buildup.

Standards & approvals

• ASTM D 3306
