EKO ANTIFREEZE is concentrated and needs to be diluted with deionized water before use. It provides effective antifreeze and antithermal protection, compatibility with elastomers, effective lubrication of the water pump, miscibility with antifreeze liquids of a similar type and stability in solutions with water of increased hardness. For effective anti-rust and anti-corrosion protection, EKO ANTIFREEZE must be used in a ratio of at least 33% by volume in water, while, depending on its dilution in higher percentages up to 50%, antifreeze protection is achieved at lower temperatures. It is recommended to change it every year and regularly check for supplements
