From Croatia to the Caribbean – water quality in ports is a gamble. Legionella, coliform bacteria and parasites lurk in the pipes.

Your fresh water tank is more than a container – it's a sensitive system that needs special attention.





Every port has different water quality. What is safe in Scandinavia can become a health risk in the Aegean.
Even on high-end yachts, no effective water treatment systems are installed from the factory. The standard water filter only retains coarse particles.
From bunkering at the marina to drawing water in the galley: three perfectly matched stages secure drinking-water quality on board – in every harbour, on every leg and even after long lay-up or overwintering.
When you bunker at the marina, the WM Filter holds back sand, rust, suspended solids and microplastics, while the integrated activated carbon also reduces contaminants such as chlorine, pesticides and pharmaceutical residues – the ideal foundation for hygienically clean water on board.

SILVERTEX® and Silvernet Flex automatically dose pure silver ions into the freshwater tank with every refill – active substance compliant with DIN EN 15030. Your water stays fresh for up to 6 months, ideal for long lay-up, charter breaks and overwintering.

Right before you draw water in the galley or shower, the UV-8 series with state-of-the-art UV-C LED technology eliminates up to 99.999% of all germs, viruses and bacteria such as Legionella or E. coli – maintenance-free, mercury-free and entirely chemical-free.

Recommended hygiene standard
Hygiene standard based on DIN 2001-2: A disinfection should be carried out at least once a year, as well as before or after holidays in southern or non-European regions. Descaling protects the boiler and metal parts and is needed one to four times a year, depending on the length of the trip and the water quality.
Disinfects water by up to 99.999 % at the tap – chemical-free & maintenance-free.
Recommended for long-distance & blue-water trips
Especially useful in waters with uncertain quality – e.g. the Mediterranean, Adriatic or worldwide.
