Shell Rotella nitrite free coolant meets specs for on-, off-highway engines

Feb. 17, 2015

Shell Lubricants is expanding its portfolio with the introduction of Shell Rotella Extended Life Coolant--Nitrite Free (ELC NF). 

The new coolant joins the Shell Rotella coolant portfolio as the companion to Shell Rotella Ultra ELC. Both products are designed to meet the requirements of a growing segment of commercial vehicles that are moving to nitrite free engine antifreeze/coolant formulations to better protect aluminum components.

“Shell Rotella ELC-NF was formulated to meet more severe operational conditions of modern, hot-running engines,” said Stede Granger, OEM technical manager, Shell Lubricants. “This is particularly important for new emission engines, especially those with exhaust gas recirculation.”

Shell Rotella ELC-NF provides improved protection of aluminum components including modern brazed aluminum heat exchangers and meets many of the newest OEM specifications. The versatile formulation may also be used in fleets that include passenger cars and light duty trucks. The coolant is proven for extended life operation in medium- and heavy-duty diesel, gasoline, and natural gas vehicles and engines.

Shell Rotella ELC-NF offers outstanding heat transfer that is superior to conventional coolants as well as excellent cavitation (pitting) and related damage protection on cylinder liners. It can help extend the life of water pumps, radiators and other cooling system components.  Rotella ELC NF offers superior heat transfer compared to conventional coolants and is compatible with other extended-life coolants. Finally, it has no supplemental coolant additives (SCA) or extender use required for the life of the coolant.

Unlike other coolants, extended life coolants are designed to go 600,000 on-highway miles or 12,000 hours in commercial applications (and beyond with proper monitoring) and provide overall reduction in cooling system maintenance. Extended Life Coolants also offer complete cooling system component protection by helping to reduce water-pump failures, hard-water-scale deposits and silicate gel. Understanding the challenges faced by consumers, the Shell Rotella coolant product portfolio has been designed to help make maintenance needs easier.
