The dialysis water treatment installation has been designed to supply one or two dialysis machines in hospitals or at home. It runs extremely quietly and is, due to its small size of 42 x 55 x 63 cm, highly versatile. The system offers easy handling with continuous monitoring of the operating parameters. The integrated disinfection and rinsing programme as well as the ultra-pure water supply without dead zones between the installation and the dialysis machine facilitates dialysis water in hygienically impeccable condition. The operating weight of the installation is only 28 kg. Additionally, the installation is equipped with casters, making it perfectly suitable for multiple purposes, even for intensive care units.
