Consumer Benefits

  • Corrosion Protection — Corrosion protection for engine metals, including aluminum, iron, copper and solder alloys.
  • Wide Service Application — Recommended as a coolant for all types of cooling systems not requiring nitrite and where freeze protection is not required.
  • Long service life — The corrosion inhibitors in Delo XLI Corrosion Inhibitor - Concentrate contain a synergistic combination of mono and di-carboxylates that provide superior protection for a minimum of 960,000 kilometers, 12,000 hours, 6 years in on-road and off-road engine applications and 32,000 hours or 6 years in stationary engines. This product does not require regular inhibitor additions if proper maintenance practices are used. 


Delo XLI Corrosion Inhibitor - Concentrate provides long life corrosion protection by using optimized and patented aliphatic carboxylate organic inhibitors that provide long lasting protection for cooling system metals and components including hard to protect aluminum.


Delo XLI helps maintain excellent heat transfer since it does not contain silicates and phosphates which can over time create deposits on heat transfer surfaces. 


Delo® XLI is also recommended for use in any OEM equipment recommending a nitrite free, water based carboxylate based corrosion inhibitor. 


OEM list for use as a cooling water inhibitor is available on the PDS.
