​COOLELF MDX -26°C provides an effective solution to the problems of corrosion affecting all the materials used in cooling circuits.COOLELF MDX -26°C performs well in the corrosion tests required by the specifications: hot plate corrosion and glassware corrosion.COOLELF MDX -26°C gives excellent protection against cavitation that can perforate liners and cause water pump problems.The additives in COOLELF MDX -26°C gives the coolant fluid: - A reserve of alkalinity (to neutralise the acids resulting from the combustion gases). - A resistance to foaming. - A compatibility with hard water (maximum 40°F). COOLELF MDX –26°C is also inert to elastomeric seals and paint.
