- Operation:Sea water pumps 1; the seawater filter 2; sea water tank 3; (No significant change, with conventional devices). Fluid in the circuit 7, powered by solar panels and / or cogeneration systems; Pump 8 has lead the cold sea water to the tank 4, via condensation tank 5; seawater pump 12 expelling the concentrated salt water back to the sea and / or the crystallization apparatus (product of salt of very good quality).All detectors fluids 10, temperature sensors, pressure sensors, fluid levels, range of vacuum; electric valves; Water pumps; Timing; sequencer; emptied non-condensable vapors; hunt the concentrated salt water; reduces the migration of sea water to fresh water, etc. ... transmit data to the electronic controller (home) to ensure optimal...Application:Clean ecological and economic way to convert sea water into fresh water.1. Solar energy Thermal panels.2. The thermal energy (cogeneration) generative, usually wasted by coastal power plants.3. The regenerative thermal energy (cogeneration) usually wasted on board Boats, ships, vessels and submarines, etc.
