Residential UV Water Treatment Systems
The PearlAqua Deca range is a series of residential UV water treatment systems designed to deliver reliable, whole-of-home disinfection while supporting a wide range of water applications. Using advanced UV-C LED technology, the Deca platform provides chemical-free treatment without the use of mercury or other harmful materials. While suited to point-of-entry residential systems, its flexible design also enables use across commercial, remote and mobile water applications.
The Deca range currently includes two models, each engineered for point-of-entry and higher flow point-of-use installations. Both systems deliver validated disinfection performance using UV-C LEDs that operate only when water is flowing, improving energy efficiency while maintaining consistent treatment. With features such as UV intensity monitoring, Dynamic Power Control and low-maintenance operation, the PearlAqua Deca range provides a practical, long-term solution for residential water treatment as well as decentralised systems, remote water supplies and emergency response applications.
