Doulton and British Berkefeld Fresh Water Systems for Boats, Yachts, Offshore Rigs etc.

Freshwater Systems for Boats, Yachts, Offshore Rigs etc

Boat owners fill their water storage tanks at the docks and often from questionable sources.

Ideally, treated water should be consumed immediately after treatment to prevent deterioration. Water that is stored in tanks at room temperatures – as in boats, for this purpose – poses a special problem. Air, heat and “sloshing” of the water will quickly dissipate bacteria inhibitors and revitalize any microorganisms that the reserve chlorine had inhibited but not killed. This hearty new culture will render the water with objectionable odours and perhaps unsafe, producing slimes and algae in the supply lines and tank.

As you enjoy your days of leisure, protect your health by keeping dangerous chemicals and pathogenic bacteria out of your water with a Doulton water purifier.
