Designing and manufacturing marine desalination systems in Sydney.<\/p>\n<\/div><\/div><\/div>
Water Makers Australia has designed and manufactured marine desalination systems in Sydney since 2020, when
\nfounders Kalim Scharenguivel and Stephen Tritton designed the first system one Sunday afternoon on the Port Hacking. Today the company builds seawater reverse osmosis watermakers for everything from small sailboats to large power catamarans across Australia, and every 240V system it has built starts with a Davey XF171S at the feed stage.<\/h1><\/div>That design choice was put to work when Mark Berg refitted his Silverton 38 Convertible at Sanctuary Cove
\nfor the fishing series Fishing Addiction, ahead of extended filming trips to the Great Barrier Reef.<\/h1><\/div><\/div><\/div><\/div><\/div><\/div><\/div>The Challenge:<\/h2>\n
The vessel\u2019s 375 litre water tank was the limit on how long it could stay out on the reef:<\/span><\/p>\n\n- Drinking water, showers, cleaning and washdown all drew on a single small tank<\/span><\/li>\n
- Extended trips meant a long steam back to a marina purely to refill<\/span><\/li>\n
- A fully kitted 38 foot flybridge convertible had limited spare space, so the system had to be distributed through the hull with custom fit out work<\/span><\/li>\n
- Reliability at the seawater feed stage was critical, because without stable feed flow the entire desalination process stops<\/span><\/li>\n<\/ul>\n<\/div><\/div><\/div>
