ReAgent Are Leading Demineralised Water Suppliers In The UK
We manufacture high-purity water products tailored to the needs of businesses across the UK, relying on our near 50 years of chemical manufacturing expertise. Our ISO-certified processes ensure consistent standards for industries that demand uncompromised quality.Our demineralised (demin) water is available in a wide range of pack sizes and formats, from 25L containers and 1000L IBCs to 25,000L bulk tankers. We also offer bespoke packaging, customised labelling, and flexible delivery options, including direct-to-customer shipments and next-day delivery.Sometimes known as demin water, demineralised water is high quality ‘pure’ water. It is made by passing non-pure water through an ion exchange resin bed. This filters out any unwanted mineral salts and impurities, like sodium or chloride. Key properties include:- Appearance: Clear, colourless liquid
- Production Method: Ion exchange resin bed filtration
- Conductivity: Low conductivity, making it unsuitable for electrical conduction
- Grades Available: Demineralised, deionised, distilled, and ultrapure water
- Packaging Options: 25L containers, 1000L IBCs, bulk tankers up to 25,000L
Common Applications Of Demineralised Water
Demineralised water is used in a variety of industries and environments. While it is mostly used in laboratory or pharmaceutical settings for preparation and testing, it is suited to a wide range of industries. The high purity of demin water, for example, makes it ideal when cleaning vehicles or metal parts because it doesn’t leave any residue behind. Demineralised water is commonly used in:- Pharmaceutical Manufacturing – As a raw material or ingredient in formulations
- Automotive Industry – Battery top-ups and cooling system maintenance
- Fire Safety – Electrical fire retardant in extinguishers due to poor conductivity
- Laboratories – As a testing medium in controlled conditions
- Industrial Cleaning – Vehicle washing and metal cleaning, leaving no mineral residue
