Shell Rotella has introduced its ELC HD high-performance extended life coolant.
The new coolant is designed to meet the rigorous demands of heavy-duty diesel, gasoline, natural gas and LNG engines, Shell Rotella said in a press release.
With advanced technology and compliance with key industry standards, Shell Rotella said ELC HD offers enhanced performance and long-term reliability for on- and off-road applications.
“Shell Rotella ELC HD is an important addition to the portfolio of Shell Rotella heavy duty coolants and engine oils designed to meet the needs of vehicles and equipment used for on- and off-highway applications,” said Julie Wright, Shell Rotella brand manager. “The coolant formulation and wide range of industry and manufacturer approvals ensure the high-performance coolant will meet the needs of several engine types.”
Shell Rotella ELC HD is formulated with modern organic additive technology (OAT) and molybdate, which provides superior corrosion protection compared to conventional fully formulated coolants.
The versatile coolant fully meets CAT EC-1 and Cummins (CES14603 & CES14439) approvals. This ensures compatibility with many modern engines, including those operating under extreme conditions.
Shell Rotella ELC HD also meets the recent European 2-EHA free coolant HSSE regulation that some European manufacturers require.
Shell Rotella ELC HD provides a range of benefits that help reduce the total cost of ownership for vehicles and equipment:
Extended coolant life for long drain intervals: Formulated to reduce downtime and maintenance costs while improving productivity.
Superior metal protection: Outstanding corrosion protection for aluminum, iron, and copper components, which has been validated through rigorous ASTM testing. This includes high-temperature and high-salinity environments.
Prevention of scale and silicate gel formation: A silicate and phosphate-free formulation reduces the risk of deposits, optimizes heat transfer and extends water pump life.
Elastomer protection: Free of 2-EHA, the coolant preserves hoses, seals, and gaskets, preventing leaks and enhancing durability.
Compatibility with other coolants: Proven to work seamlessly with other similarly formulated OAT coolants, simplifying top-ups and maintenance.
Engine Safety: Silicate, borate & phosphate free.
Shell Rotella ELC HD is also formulated to provide optimal water pump protection, achieving a superior rating in the 300-hour pump abuse test (ASTM D2809). This ensures reduced downtime, minimized repair costs, and improved operational reliability.
Shell Rotella said ELC HD meets or exceeds the following industry standards and OEM requirements:
ASTM Standards: D3306, D4985, and D6210
OEM Approvals:
Caterpillar EC-1
Cummins CES14603 and CES14439 (Mining applications)
Meets European HSSE regulation for 2-EHA-free coolants
Shell Rotella ELC HD is available in 50/50, 55/45, and concentrate formulations, offering flexibility to suit diverse operational needs.
The product is in stock and ready to ship, ensuring quick and easy access for trucking fleets, construction, agriculture, and mining operations.
