With the production of water disinfection systems based on ultraviolet radiation and ozone, we are contributing to the replacement of chemicals in water disinfection as far as possible. This way, we counteract environmental pollution and the formation of resistant germs. Our claim is to produce the best UVC water disinfection systems of this kind. They have excellent quality, high efficiency and are easy to use. With the PURE Water systems, we inspire our private users and show that environmental protection is possible with improved properties at the same time. Water treated with PURE Water is safely freed from germs without any changes in taste or odour. Since 2018, UST has been manufacturing ULTRA V custom-fit solutions for disinfecting water in cooling circuits, sprinkler systems, animal husbandry and other commercial water systems.
