bett Today every chance to save energy counts. That’s why we never stop improving our technology. Our Alfa Laval AQUA Blue freshwater generator builds on over six decades of application innovation, comprising the best aspects of both shell-and-tube and plate-based desalination. With its 3-in-1 AQUA plate technology, it drastically reduces seawater use and power consumption. But the story doesn’t end there. Electrical power requirements were cut in half with the original AQUA Blue C-type - and with the AQUA Blue S-type, we cut them again.

The AQUA story ke The story of AQUA technology is one of smart innovation that results in energy, space and cost savings. With the AQUA Blue S-type, the benefits are even more remarkable. Smarter for ship owners The AQUA Blue S-type is the newest application of Alfa Laval’s unique AQUA technology, which was first introduced in 2008. AQUA technology uses specially designed 3-in-1 plates to provide today’s most energy-efficient desalination process – literally cutting seawater needs and power requirements in half compared to conventional freshwater generators. The AQUA Blue S-type has the...

eps getting better Smarter for shipyards Besides having a footprint up to 15% smaller, the AQUA Blue S-type offers shipyards a considerable amount of new flexibility, including a range of connection alternatives. Because it makes use of the vessel’s seawater cooling system pumps, it employs a smaller ejector and a smaller, separately installed ejector/feed water pump. Likewise, the pipework can be both shorter and smaller in diameter. In addition, the S-type handles a wider span of pressures, which means the configuration can be adapted to the highest or lowest water level. An adapted...

ro Whether configured as an S-type or a C-type, the AQUA Blue freshwater generator handles the entire desalination process with a single plate pack and one type of titanium plate. The result is an energy-efficient and easily managed solution. Serving it all on one plate AQUA Blue comprises titanium plates with a unique 3-in-1 design. Fitted with two gasket configurations, they allow evaporation, separation and condensation to occur within a single, uncovered plate pack. These 3-in-1 plates are the first to be purpose-built for desalination, rather than modified from a heat exchanger design....

Room to move and grow Performing desalination in a single plate pack creates a space-saving and easily maintained freshwater generator. Because the process vacuum is inside the plate pack, no outer shell is necessary. The plate pack simply slides open for maintenance, which keeps the service area within the equipment footprint. The pumps and pipes associated with AQUA Blue are smaller than those of conventional freshwater generators, especially if an AQUA Blue S-type is used. That simplifies installation, and additional plates can often be added if capacity needs change over time.

Doing the job with l The AQUA Blue freshwater generator combines high water quality with high energy efficiency. Combined with its low maintenance requirements, this results in low lifecycle costs. Less seawater, energy and impact AQUA Blue’s optimized technology converts more of the feed water into fresh water. Furthermore, it reduces the seawater used for cooling by half. This means only half the energy is needed for pumping, which is a large portion of the overall power consumption in generating fresh water. If an AQUA Blue S-type is chosen, the use of the vessel’s seawater cooling...

Less work and worry Just as it requires less electrical power, AQUA Blue demands less energy from the crew. AQUA Blue is designed for peace of mind and start-and-forget operation. Regulation of the seawater flow optimizes AQUA Blue’s performance, ensuring high-quality fresh water with a maximum salinity of 2 ppm. The quality is continuously monitored by the control system, while expanded instrumentation offers a clear overview of the process. When inspection or maintenance is needed, the plate pack simply slides open for easy access to the interior. But the maintenance intervals are long,...

Keeping it simple AQUA Blue is good news for shipyards, ship owners and ship operators alike. From start to finish, it offers ease, reliability and the global security of working with Alfa Laval. Easy to fit or retrofit Because it cuts seawater needs in half, AQUA Blue can be installed with smaller pumps, smaller pipes and less space and piping overall. The S-type configuration has a range of connection alternatives and reduces footprint by up to 15% over the already small C-type. AQUA Blue Apart from its minimal equipment size, AQUA Blue has a service area up to 50% smaller than that of...

Durable construction Once installed, the freshwater generator can be expected to last the lifetime of the ship. AQUA Blue has an extremely robust construction, with piping available in duplex steel, stainless steel or bronze. The wetted surfaces are made of titanium, which means they will not corrode or erode. Lasting performance AQUA Blue’s own reliability is matched by that of working with Alfa Laval. With over 60 years of experience in freshwater generation, Alfa Laval is your guarantee of optimized performance, both today and tomorrow. Alfa Laval is there to support you, from design and...
