Delivering value for you
Corrosion protection for engine metals, including aluminum, iron, copper and solder alloys.
Recommended as a coolant for all types of cooling systems not requiring nitrite and where freeze protection is not required.
The corrosion inhibitors in Delo XLI Corrosion Inhibitor - Concentrate contain a synergistic combination of mono and di-carboxylates that produce superior protection for a minimum of 600,000 miles, 960,000km, 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 ot require regular inhibitor additions if proper maintenance practices are used.
Delo XLI Corrosion Inhibitor- Concentrate is a super concentrate and should be diluted to 5.5%-10% with good quality water before use. Compatible with glycol-based engine coolants but further dilution of the Delo XLI inhibitors by more than 25% with other corrosion inhibitor technologies will reduce the effectiveness of this product.
Silicate and phosphate free formulation does not contribute to deposit build up, as can be seen with phosphate and silicate containing coolants, which can help maintain heat transfer efficiency.
No regular inhibitor additions and longer service life means lower overall maintenance costs.
based on low toxicity inhibitor's this product is readily biodegradable. The extended service life characteristic of this product contributes to the protection of the environment due to less frequent fluid disposal.
inhibitor concentration testing can be easily done using a brix refractometer.
