Rainwater UV 4100 is designed to use the UV-C wavelength to inactivate microorganisms in water without chemicals. With a maximum flow rate of 2.1 m³/hour, it delivers stable sterilisation performance in domestic and commercial water applications.
Higher lamp power delivers effective UV-C sterilisation performance in heavy-use scenarios.
Raises the hygiene level of water by providing physical disinfection against bacteria, viruses and protozoa.
As UV technology adds no chemicals to the water, it preserves the water's natural character.
Aims for safe use with mains water, well water, spring water and stored water, together with pre-filtration.

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 UV 4100 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 2.1 m³ of water per hour (at a dose of 25 mJ/cm²).
Water passes through a treatment chamber containing a 40 W UV lamp; UV-C light inactivates microorganisms by preventing them from reproducing. The UV unit is installed on its own; for best results, it should be preceded by a mechanical and activated carbon pre-filter, because suspended particles prevent UV light from penetrating the water.
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 2.1 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.
