Light Diesel Oil (LDO) Red Grade is a medium-viscosity industrial fuel derived from the distillation of crude oil and blended with selected residual fractions. The Red color is generally added as a dye for identification of industrial/off-road fuel applications. LDO is widely used in boilers, furnaces, thermic fluid heaters, diesel generators, and low/medium RPM engines due to its reliable combustion characteristics, higher flash point, and economical operation.
It offers stable thermal efficiency, easy handling, and consistent performance in industrial heating and power generation systems. Compared to heavier furnace oils, LDO burns cleaner and requires less preheating, making it suitable for continuous industrial operations.
