Marine engine cooling systems operate in environments characterized by continuous load, high humidity, and proximity to saltwater, requiring coolant formulations with stable corrosion control and long-term reliability.
SLC-OAT-LL Coolant Additive is designed for use in closed-loop freshwater cooling systems commonly found in marine engines and auxiliary power units. Its Pure OAT formulation protects critical materials such as cast iron, aluminum alloys, copper, and solder joints without forming scale or deposits.
Key advantages in marine applications include:
-
Consistent corrosion protection in mixed-metal systems
-
No sediment formation that could restrict heat exchangers
-
Extended service life, reducing onboard maintenance frequency
Application considerations:
-
Best suited for deionized water circuits separated from sea water
-
Proper formulation and routine monitoring are recommended
Compared with traditional inorganic marine coolants, SLC-OAT-LL provides a technically stable and long-life solution aligned with modern marine engine design practices.
