Demineralised Water is a clear, colourless and odourless purified water that has been refined by removing harmful mineral ions, salts and other impurities such as Calcium, Magnesium, Sodium, Chloride, Sulphate, Nitrate and bicarbonate that can cause destabilisation of other chemicals with which it is mixed. It is also known as deionised water and used in OEM Approved coolant Premix solutions. APPLICATION Demineralised Water is suitable for mixing with engine coolants to achieve the desired concentration level of the coolant. It can be used with both Type A (Anti-Freeze Anti-Boil) coolants and Type B (Inhibitor Only) coolants. It is suitable for all conventional type coolants including OAT and Hybrid type concentrates. It reduces mineral scale build up and the possibility of premature corrosion of the cooling system. It also lowers the possibility of a chemical reaction between the coolant, water and materials used in the radiator. If used as top up, it is recommended that the coolant also be topped to the correct concentration level. (Penrite recommend using Penrite OEM Approved Coolants for optimum performance, protection and longevity of the coolant and the cooling system). Demineralised Water can also be used in lead acid batteries as the reduction in mineral and salt ions that are commonly found in tank and tap water can drastically shorten the lifespan of a lead-acid battery. Effects of not using demineralised water are corrosion of the positive plate and mineral contaminates in the electrolyte solution which can effect metallic components and hence a loss in performance. Demineralised Water can also be used in many other applications such as steam irons, aquariums, autoclaves, laboratory, laser cutting and many more. It is also ideal for watering indoor and delicate plants as it will not cause a build-up of minerals in the soil.
