Shell Rotella ELC NF 50/50

Shell Rotella ELC NF 50/50

Shell ROTELLA ELC Pre-diluted 50/50 is a premium extended life coolant and antifreeze designed for heavy-duty diesel, gasoline, and natural gas-powered engines.

  1. Long Service Life: This coolant has a minimum life of 600,000 miles or 12,000 hours off-road without the need for ELC Extender, reducing the frequency of coolant changes.
  2. Advanced Inhibitor Technology: Shell ROTELLA ELC contains a unique extended life carboxylate inhibitor system and nitrite/molybdate as secondary inhibitors, eliminating the need for traditional ELC Extender and Supplemental Coolant Additives (SCAs). This advanced formulation ensures superior protection and longevity.
  3. Comprehensive Metal Protection: It provides excellent long-term corrosion protection for all cooling system metals, including aluminum, brass, cast iron, steel, solder, and copper.
  4. Heat Transfer and Efficiency: The coolant is designed to offer excellent heat transfer properties, about 8% better than conventional heavy-duty silicate-containing coolants. This improves the efficiency of the engine cooling system.
  5. Environmental Consideration: Shell ROTELLA ELC is free from silicate, borate, nitrate, or phosphate, aligning with environmental standards.
  6. Water Pump Seal Life: The low dissolved solid levels in the coolant help in improving the life of water pump seals.
  7. Ease of Maintenance: The product simplifies maintenance routines with no regular SCAs required and no silicate dropout or gel formation during use or storage. It is also compatible with conventional coolants, although dilution with non-equivalent coolants should not exceed 15% to maintain extended life properties.
  8. Safety and Environmental Protection: Shell ROTELLA ELC is designed to be safe for use, posing no significant health or safety hazards when used as recommended. Users are advised to maintain good standards of personal hygiene and environmental responsibility, such as disposing of used oil properly.
Shell Rotella ELC

Shell Rotella ELC

Shell ROTELLA ELC (Extended Life Coolant) stands out as a high-performance engine coolant, offering substantial benefits for heavy-duty diesel, gasoline, and natural gas-powered engines. Its exceptional service life, lasting up to 600,000 miles or 12,000 hours in commercial applications, greatly reduces the need for frequent coolant changes. A key feature of Shell ROTELLA ELC is its advanced corrosion protection capabilities, effectively safeguarding all coolant system metals, including aluminum, brass, cast iron, steel, solder, and copper, against corrosion and cavitation.

Notably, Shell ROTELLA ELC is a nitrite-free formula, aligning with the latest environmental standards and making it ideal for modern engines, particularly those with exhaust gas recirculation (EGR) systems. This nitrite-free composition not only enhances the coolant's environmental friendliness but also minimizes the risk of cylinder liner cavitation, a common issue in heavy-duty engines. Additionally, the coolant maintains its heat transfer efficiency throughout its service life, ensuring engines run cooler and more efficiently.

Maintenance routines are simplified with Shell ROTELLA ELC, as the need for supplemental coolant additives (SCAs) is eliminated. This reduction in maintenance requirements not only eases operational procedures but also minimizes the risk of coolant incompatibility issues. The coolant's compatibility with most other ELCs and many non-ELC coolants further adds to its versatility, making it suitable for a wide range of equipment and meeting various OEM specifications.
