The SHIRINDA SAE50 TBN80 is recommended for all low speed 2-stroke engines operating on high sulfur residual fuel. Suitable for ships with an exhaust gas aftertreatment system. Based on pioneering chemistry, it has a high BN of 80 and its highly capable neutralization of reducing acids. Neutralizes sulfuric acid and prevents low temperature corrosion of modern 2-stroke engines. When using high sulfur heavy fuel oil (HSHFO), it efficiently maintains the cleanliness of the cylinder and prevents damage to the engine. Especially suitable for long hours of intense engine operation.
