De-Ionised Water 25L Drum (Sold Per Ltr) - DEI0000NH

Water where ions are not present, commonly used in engine cooling systems. The low level of minerals results in minimal scale build up. Deionised water, or DI water, is sometimes called demineralised water, or DM water. It is water which has had (most of) the ions removed. Ions are atoms or molecules which have either more electrons than protons, making a negative ion (an anion) or fewer electrons than protons, making a positive ion (called a cation). De-Ionised Water 25L is not the same as distilled water, although they are both forms of purified water. While the deionisation process produces high purity water by removing mineral ions it will not significantly remove any uncharged organic molecules. Whereas the distillation process boils water and then condenses the vapor which leaves both solid, mineral contaminants and organic contaminants behind. De-ionised water has a range of uses. In a lab it can be used when the purity of water needs to be known and for sterilization of equipment. Industrial processes include chemical processing, pharmaceuticals, power, micro-electronics and petrochemicals. Regular tap water is unsuitable for many cooling applications due to the minerals that contribute to the electrical conductivity of water, de-ionised water has a far lower level of conductivity and does not result in unwanted scale build up. It can also be used in boiler feed, extinguishing fires, aquariums and automotives.
