Leading Demineralized Water Suppliers in the USA

ReAgent is a multinational company with almost 50 years of experience in chemical manufacturing. We produce high-purity water products tailored to the needs of businesses across the USA.

Our demineralized (demin) water is available in a wide range of pack sizes and formats, from 1- to 55-gallon containers up to bulk tankers. 

We also offer custom packaging and labeling along with flexible delivery options, including direct-to-customer shipments and next-day delivery.

Sometimes known as demin water, demineralized water is high-quality “pure” water. It’s 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. 

Common Applications of Demineralized Water

Demineralized water is used in a variety of industries and environments.  While it’s mostly used in laboratory or pharmaceutical settings for preparation and testing, it’s suited to a wide range of industries. 

The high purity of demin water makes it ideal for cleaning vehicles or metal parts because it doesn’t leave residue. Demineralized water is commonly used in:

  • 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

Production & Testing of Demineralized Water

ReAgent produces demineralized water using an ion-exchange process. 

Water is passed through specialist resin beds that remove unwanted salts and mineral impurities such as sodium and chloride. The result is highly purified water that performs consistently across industrial and laboratory environments.

Additional testing, technical support, and purification steps are available upon request, ensuring the right grade of water is supplied for every application.
