Delo ELI Corrosion Inhibitor

Delo® ELI Corrosion Inhibitor is a water-based inhibitor, super concentrate, using a patented synergistic combination of aliphatic carboxylates that also contains nitrite and molybdate as secondary inhibitors.


Delo ELI Corrosion Inhibitor delivers value through:

  • Long Service Life 
    600,000 miles, 1,000,000 km, 12,000 hours, 6 years in on-road and off-road engine applications and 32,000 hours or 8 years in stationary engines with yearly testing required.

  • Corrosion Protection
    Extended life corrosion protection in aqueous solutions for engine metals, including aluminum, iron, steel, brass, copper and solder alloys.

  • Compatibility
    Compatible with glycol-based engine coolants and other water based corrosion inhibitors. Dilution of this product by more than 25% with other inhibitor technologies will reduce inhibitor protection performance. Excellent elastomer compatibility.


  • Delo ELI Corrosion Inhibitor is a water based, extended life corrosion inhibitor based on aliphatic carboxylates that is recommended for use in a wide variety of cooling systems in industrial, on-road, off-road and stationary applications.


Delo ELI Corrosion Inhibitor is recommended for use in industrial and commercial cooling systems where the OEM recommends a silicate free, nitrite containing water based corrosion inhibitor system.
