2 3 Alfa Laval on board Alfa Laval can be found on most ships and in most onboard processes. This includes freshwater generation, where Alfa Laval has led the way since 1955. Drawing on our many years of experience, we create new advances based on well-known technologies. A perfect example is the AQUA freshwater generator, which takes vacuum desalination to new levels of efficiency and economy. AQUA’s all-in-one plate technology cuts seawater requirements in half. And just as importantly, it makes AQUA exceptionally easy to operate and maintain.

4 5 Two sides of the AQUA story The story of the AQUA freshwater generator is the story of a remarkable innovation, fully tested both on and off shore. AQUA represents a major process breakthrough, with benefi ts for ship owners, ship operators and shipyards alike. One half of the story … Through unique plate technology that requires only half as much seawater, AQUA generates both fresh water and savings for ship owners and ship operators. Half the seawater fl ow translates into half the pumping requirements, with a corresponding reduction in electrical energy. In other words, less fuel is...

6 7 4 1 6 6 7 8 1 3 5 2 AQUA – inside and out The AQUA freshwater generator handles the entire desalination process with a single plate pack and one type of titanium plate. The result is an effi cient and easily handled solution. Serving it all on one plate The AQUA plate pack contains purpose-made plates with 3-in-1 technology. Evaporation, separation and condensation occur on a single type of plate, designed with Alfa Laval’s fl uid handling expertise. Feed water passes through the lower section of the plate pack, where it is evaporated at 40-60°C in a vacuum of 85-95%. As the vapour...

8 9 Doing the job with less The AQUA freshwater generator operates economically with only half the seawater fl ow. Though it provides exceptional longterm effi ciency, it requires only minimal maintenance. Less seawater, less impact AQUA makes effi cient use of the heat that already exists on board, employing jacket water, steam injection or a Hot Water Loop as a heating medium. But just as importantly, it makes effi cient use of seawater. This means that AQUA provides better operating economy, not only compared to shell-and-tube models, but also compared to other plate-based freshwater...

10 11 Keeping it simple With its streamlined installation and maintenance-friendly setup, the AQUA freshwater generator reduces both initial investments and lifecycle costs. This makes it an ideal solution for use on ships and rigs, as well as in remote onshore locations. Easy to fit or retrofit AQUA means good news, both for shipyards and for those looking to retrofit. Possible to install in any direction, it allows for a more compact and flexible installation. In fact, AQUA saves considerable space and weight over other types of freshwater generator. Not only does AQUA itself have a...
