Manufacturer's description

Cat ELI (Extended Life Inhibitor) Corrosion Inhibitor Premix is a long-lasting coolant for marine and industrial engines working in environments that do not experience freezing temperatures — it does not provide freeze protection. It uses an active-protection technology similar to Cat ELC, avoiding the silicate-based inhibitor "coat" that conventional coolants and SCAs lay down throughout the cooling system, which slows heat transfer and reduces efficiency; instead Cat ELI sends its organic additives only to areas susceptible to corrosion. Benefits include lower owning and operating costs (lasting three to six times longer than conventional coolants or SCA-treated water, with less frequent checks, inhibitor replacement and drains/flushes), maximum protection against pitting and corrosion for aluminum, brass, copper, iron and steel, and, being non-glycol, easier environmentally friendly coolant changes without residue buildup. In testing, Cat ELI showed markedly better protection of aluminum components than conventional SCA products. Typical life is 3,000 hours between SCA additions, extendable 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).

Applications

• Long-lasting coolant for marine and industrial engines working in environments without freezing temperatures.

Performance & benefits

• Lasts three to six times longer than conventional coolants or commercial supplemental coolant additives (SCA) mixed with water, lowering owning and operating costs.
• Reduces maintenance costs through less frequent coolant-health checks, inhibitor replacement and drains/flushes.
• Fewer repairs needed thanks to improved corrosion protection.
• Uses inhibitors that give superior protection against pitting and corrosion for aluminum, brass, copper, iron and steel.
• Contains no glycol, supporting environmental sustainability.
