RAVENOL HDT Heavy Duty Truck Cool. Concentrate

RAVENOL HDT Heavy Duty Truck Cool. Concentrate is an eco-friendly 1.2- Ethanediol (monoethylene glycol) based on low silicate technology in combination with nitrite and molybdate coolant for cooling circuits in combustion engines and in particular for heavy duty applications, which provides maintenance-free corrosion and frost protection. This product is formulated based on a proven inhibitor development as an extended life coolant.

RAVENOL HDT Heavy Duty Truck Cool. Concentrate is suitable for gasoline, diesel, and natural gas powered automotive and industrial engines and is particularly recommended for heavy duty engines, where high temperature aluminium protection is important.

The quality of an antifreeze is no longer just determined by the antifreeze effect (which automatically exists in an ethylene-glycol based product), but by the rust protection. That is why automakers subject antifreeze to lengthy corrosion and cavitation tests.
