RWO GmbH

About RWO GmbH

Since 1975, this engineering company out of Bremen, Germany, has been focused on one thing - building reliable water treatment systems for ships. Their gear isn’t designed for marketing flash; it’s designed to pass inspections, survive long hauls, and meet environmental standards that get stricter every year. With more than 16,000 units installed worldwide, their footprint in the maritime sector is hard to ignore. Shipowners and yards have come to rely on them for everything from bilge water separation and sewage treatment to fresh water generation and ballast water management. Their systems show up on all kinds of vessels - bulkers, tankers, cruise ships, offshore support - and they’ve earned their place through solid performance. RWO GmbH keeps its edge by sticking to original design standards. That applies not just to the machines but also to their spare parts, which are manufactured to match exact system specs. Using non-OEM components might save a few bucks up front, but it’s a fast track to compliance issues and breakdowns. That’s why they’ve built their logistics around delivering the right part, fast - no guesswork, no gambling. Support is a major part of the company’s offering. Crews can count on them for commissioning, training, maintenance, and emergency repairs, with a global network in place to minimize downtime. Whether it’s a last-minute overhaul or scheduled servicing, their technicians show up prepared and equipped. The company doesn’t try to be everything to everyone. Instead, it focuses on water - making sure it’s clean when it needs to be and compliant when it matters most. That’s what they’ve done for nearly 50 years, and that’s what they continue to deliver for shipowners around the world.
