Delo XLI Corrosion Inhibitor

Delo XLI Corrosion Inhibitor is also recommended for use in any OEM equipment recommending a nitrite free, water-based carboxylate based corrosion inhibitor, or where heavy duty mixed OEM fleets require a single coolant/inhibitor for ease of handling on site.

The results are listed below: 

• LD50 >2000 mg/kg (oral toxicity according to OECD guideline No 401)
• LC50 >1000 mg/l (fish toxicity according to OECD guideline No 203)
• Biodegradability: 92% (18 days) (test according to OECD guideline No 301E)

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

Corrosion Protection — Provides superior corrosion and cavitation protection for engine metals, including aluminum, iron, copper and solder alloys. The OAT technology provides ASTM D3306 and ASTM D6210 performance when used in glycol based antifreeze coolants.

Wide Service Application — Recommended as a coolant for all types of cooling systems where freeze protection is not required.

Long service life — The corrosion inhibitors in Delo XLI Corrosion Inhibitor 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.

Compatibility — 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 these products.

Heat Transfer — 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.

Low Maintenance — Requires very low maintenance compared with conventional products which require SCA.

Improved economics — No regular inhibitor additions and longer service life means lower overall maintenance costs.

Excellent toxicological and environmental aspects — Based on low toxicity inhibitors these products are readily biodegradable. The extended service life characteristic of this product contributes to the protection of the environment due to less frequent fluid disposal.

Easy Testing — Inhibitor concentration testing can be easily done using a brix refractometer.
