Shell Lubricants has introduced 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.
The company says 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,” says 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, LNG and natural gas vehicles and engines.
The company says 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.
“As engine technology advances, we continue to develop new products such as the Shell Rotella ELC NF with our customer’s current and future maintenance needs in mind,” said says Guerrero, global marketing manager.
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, according to the company. Extended life coolants also offer complete cooling system component protection by helping to reduce water-pump failures, hard-water-scale deposits and silicate gel.
Shell Rotella ELC NF meets industry required ASTM D3306, D4985 and D6210 and TMCRP 329 and RP 364 requirements. Shell Rotella ELC NF is also suitable for the following applications:
Detroit Diesel 93K217
Cummins Medium and Heavy Duty On-Road Engines1
Navistar MPAPS B-1 Type IIIA (formerly Int CEMS B-1)
Volvo TSI 184-001
