Nitrite ree ELC Coolant- Modern Cooling Systems
Shell Rotella® extended life coolants (ELC) are formulated to:
- Provide high performance protection for today’s heavy-duty diesel engines
- Provide effective heat transfer, freeze and boiling protection
- Provide corrosion protection for the cooling system
Outstanding Heat Transfer
Superior heat transfer to conventional coolants
Extended Life Capability
Up to 1,200,000 miles in Class 8 trucks*, up to 600,000 miles or 12,000 hours in other commercial applications, or 150,000 miles (6 years) in passenger cars and light trucks
Compatibility with Other Coolants
Miscible and compatible with other extended life AFC
Reduced Coolant Maintenance and Lower Total Cost of Ownership
No SCA or Extender Use Required for the life of the coolant; silicate free formulation leading to longer water pump life and no silica gel formation
Excellent Cavitation (Pitting) Protection
Excellent protection against cavitation related damage on cylinder liners
Excellent Corrosion Protection for Modern Engines
Nitrite-free formulation provides protection against aluminum corrosion, aluminum being material of choice for modern engines
Established Track Record of Use
Current market dominant technology for factory fill applications of major heavy duty OEMs
The Shell Rotella® brand offers a complete product line of ELC and Fully Formulated engine coolants, designed to deliver:
- Protection against overheating – Excellent heat transfer properties allow heat to transfer more effectively, protect against freeze and boil-over and help keep engines running cool
- Corrosion protection – Corrosion inhibitor technology protects metals against all forms of corrosion
- Maintenance savings – Technology helps extend coolant life and prolong the life of seals, hoses and other cooling system components – helping reduce overall maintenance costs
Shell Rotella ELC NF is designed to go 1.2M on-highway miles (and beyond with proper monitoring) and provide overall reduction in cooling system maintenance. ELCs also offer complete cooling system component protection by helping to reduce water-pump failures, hard-water-scale deposits and silicate gel (the green goo you sometimes see). We understand HD truck and equipment operators challenges and have designed a product portfolio to help make maintenance needs easier.
Shell Rotella® ELC NF (Nitrite-Free) is ideal for mixed fleets because it is designed for use in commercial trucks, light duty trucks, and automobiles – including many electric and hybrid vehicles. Always follow the vehicle owner’s manual. Shell Rotella® ELC Nitrite Free Coolants – A high quality, extended life, nitrite free antifreeze/coolant (AFC) designed to meet the latest trend in commercial and diesel engines away from nitrited AFC. Nitrite free AFC improves protection of aluminum heat exchangers (radiators and heater cores). Shell Rotella® ELC NF AFC is colored red to match many ELCs in the market today and based on the proven Shell Rotella® ELC AFC technology.
