Freshwater Generator / Watermaker · Freshwater Generators
On ships, the need for freshwater for drinking, cooking, and sanitation is constant. To meet this demand, Alfa Laval offers the AQUA Fresh Water Generator, a plate-type vacuum evaporator. This system utilizes waste heat from the ship's engine to produce freshwater from seawater. Available in various sizes, ranging from AQUA-5 to AQUA-120, the generator can produce between 5 and 120 tons of freshwater per day. The AQUA Fresh Water Generator's construction features titanium plates for the evaporator and condenser, ensuring resistance to corrosion. It operates with a vacuum between 85-95%, requiring a minimum seawater pressure of 3 bar at the ejector inlet. The system's drive type is passive, relying on the engine's waste heat for operation. Routine maintenance is essential for optimal performance. This includes checking for plate calcification and corrosion, inspecting gaskets for wear and tear, and monitoring the ejector's vacuum and for air leaks. Regular cleaning of the demisters and sensor calibration are also important to maintain water quality.
