What We Do

We have been supplying commercial vessels with fresh-water treatment solutions for more than 25 years. We custom design and manufacture:

- Reverse Osmosis units
- Mineralizing systems
- Fresh water treatment systems (disinfection and pH-correction units)
- Fresh water units
- Pool systems
- Filtration systems

All systems are manufactured according to a vessel's requirements and conform to all WHO and USPHD regulations. Our company supplies systems for new construction projects as well as refits and work with major shipyards such as Meyer-Werft, MV Werften, MHI and KrögerWerft.

In addition to the manufacture of new units, we provide comprehensive maintenance and replacement parts supply services. We will assist you with service and parts scheduling and stay current on regulatory issues to lessen the burden on you.
