NASHVILLE, Tenn. — Shell demonstrated at the Technology & Maintenance Council meetings a new nitrite-free extended life coolant.

Shell Rotella ELC-NF was added to the company’s coolant portfolio as a companion to its Rotella Ultra ELC.

“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 says ELC-NF provides improved protection of aluminum components including brazed aluminum heat exchangers. Its heat transfer is superior to conventional coolants and it offers protection against cavitation, Shell claims. It can also extend the life of water pumps, radiators and other cooling system components.

“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 Chris Guerrero, ‎global marketing manager, Shell Lubricants. “We know our hardworking customers are looking for the best products that help them meet today’s and tomorrow’s challenges for on- and off-highway engines. Shell is excited to offer a new product that fulfills customer needs, and is a great addition to our coolant portfolio.”

The new coolant is designed to run 600,000 on-highway miles or 12,000 hours in commercial applications with proper monitoring.
