RAVENOL OTC Organic Techn. Coolant Concentrate C12+ is an eco-friendly 1.2- Ethanediol (monoethylene glycol) based silicate, borate, nitrite and phosphate-free coolant for cooling circuits in combustion engines which provides maintenance-free corrosion and frost protection. This product is formulated based on a proven inhibitor development with the organic additive technology OAT as an extended life coolant.
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.
RAVENOL OTC Organic Techn. Coolant Concentrate C12+ protects the cooling system from rust, frost, and in summer, from overheating.
Application Note
RAVENOL OTC Organic Techn. Coolant Concentrate C12+ with highly effective frost and rust protection. Usable in cooling systems with all-aluminium engines. Mix according to chart. Follow manufacturer's recommendations.
Even in summer coolant must contain enough antifreeze to ensure good corrosion and overheating protection.
Instructions: Clean cooling system, check for leaks, flush.
Mix RAVENOL OTC Organic Techn. Coolant Concentrate C12+ with distilled water (per mixing chart) and add. Allow engine and heater to warm up, add coolant to fill level.
RAVENOL OTC Organic Techn. Coolant Concentrate C12+ can also be used in geothermal probes and geothermal collectors as recommended list of LAWA (Federal / State Working Group on Water in Germany).
MAN information for use:
Mixing prohibited with Type NF and Type N. Do not use silicone radiator hoses per MAN 334 Type 3 (blue) with coolants per MAN 324 Type SNF.
