Rainwater DUO UV 2100 is designed with a pre-filtration approach that helps reduce suspended solids in the water before UV treatment. Mechanical and activated carbon pre-filtration helps UV light penetrate the water more effectively, taking sterilisation performance to the next level.
Reducing suspended solids prevents shadowing of the UV light, increasing disinfection efficiency.
Compact compared with other UV units in its class, it offers an easy, practical installation.
High-quality materials in all components aim for durable, long-lasting use.
UV technology validated by biodosimetry testing offers an effective method for microbiological safety.

Water passes through UV-C light; microorganisms are inactivated without the use of chemicals.

A spring support holds the quartz glass in place and protects it during transport.



The confidence of flawless quality: freshness and peace of mind for everyday life.

Well, rain or tank water may carry a risk of bacteria and viruses; mains water can also become contaminated in building plumbing and storage tanks. Rainwater DUO UV 2100 is a system that sterilises water with UV-C light without using chemicals; it does not alter the taste or odour of the water and creates no by-products.
For apartment buildings and housing estates, hotels, restaurants, cafés, social and sports facilities, agricultural and livestock applications, and places that use rain and well water. It sterilises up to 1.7 m³ of water per hour (at a dose of 25 mJ/cm²).
Water passes through a treatment chamber containing a 25 W UV lamp; UV-C light inactivates microorganisms by preventing them from reproducing. In the DUO system, there is a pre-filter ahead of the UV unit. The pre-filter captures suspended solids, helping UV light penetrate the water effectively and improving sterilisation performance.
Installed on the water inlet line. The UV lamp is replaced once a year and the quartz sleeve on average every 5 years. For maintenance, you can submit a request via the technical service form.

It sterilises water with UV-C light, inactivating microorganisms such as bacteria and viruses without using chemicals.
No. UV sterilisation involves no chemicals; it does not alter the taste or odour of the water and creates no harmful by-products.
It sterilises up to 1.7 m³ of water per hour at a dose of 25 mJ/cm²; the connection size is 3/4” + 1”.
The UV lamp is replaced once a year and the quartz sleeve on average every 5 years.
Yes, it is recommended. Suspended particles prevent UV light from penetrating the water, so a mechanical and activated carbon pre-filter is used ahead of the UV unit. In DUO and TRIO systems, the pre-filter is built into the system.
