Ravenol OTC - Protect C12+ Premix -40°C


RAVENOL OTC Organic Technology Coolant PREMIX -40°C is a ready-to-use, 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 Technology Coolant PREMIX -40°C protects the cooling system from rust, frost, and in summer, from overheating.

Application Notes

RAVENOL OTC Organic Techn. Coolant Premix -40°C is a prediluted coolant with frost and rust protection for year-round use in automotive engines.

Even in summer coolant must contain enough antifreeze to ensure good corrosion and overheating protection.

Instructions: Add RAVENOL OTC Organic Techn. Coolant Premix -40°C to radiator to fill line.

RAVENOL OTC Organic Techn. Coolant Premix -40°C can also be used as a “ready for use” dilution in geothermal probes and geothermal collectors as recommended list of LAWA (Federal / State Working Group on Water in Germany). RAVENOL OTC Organic Techn. Coolant Concentrate is included in the list of recommendations of the LAWA for water management requirements for geothermal probes and geothermal collectors.
