Technology company, Alfa Laval has launched a new freshwater generator "AQUA Blue S-type" said to reduce power consumption by about 70%.
The product which follows a 2008 model uses 3-in-1 AQUA plate technology as the original C-type configuration but with maximized energy efficiency and capacity-to-footprint ratio by making use of the vessel's existing seawater cooling system pumps.
Alfa Laval said the system "cuts electrical power needs by 70% compared to conventional freshwater generators, and it shrinks the already small AQUA Blue footprint by up to 15%."
“AQUA freshwater generation technology revolutionized energy use in a very well-established application,” says Alex Jönsson, Global Business Manager for Alfa Laval freshwater generators.
“With the AQUA Blue S-type, we further reduce the energy-related costs for shipowners – as well as the installation costs for shipyards.” He added.
The new AQUA Blue S-type FWG also boost flexible installation process with various connections options. Because of the vessel's seawater cooling system pumps application, it employs a smaller ejector and a smaller, separately installed ejector 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 configuration is able to deal with higher pressure in the overboard line, which allows the freshwater generator to be placed more freely on board.
“AQUA Blue is designed not only for energy and footprint savings, but also to last the lifetime of the vessel.” says Jönsson.
