The Sea Recovery Aqua Whisper Mini Series are the smallest line of watermakers.  The low-hassle Aqua Whisper Mini is engineered to fit anywhere.  Measuring at about 2 – 3 cubic feet, sail and small power boaters have the opportunity and the convenience of a Sea Recovery watermaker without space restrictions.  Smaller than a 20 gallon water tank, yet able to produce between 170 – 750 GPD (644 – 2,839 LPD) in capacity, this desalinator is the perfect seaworthy companion for the solo cruiser.  Weighing at most, 130 lbs, the Aqua Whisper Mini is also more convenient than hauling around a full water tank that adds about 8 pounds per gallon to your boat.  To illustrate, if a 34 gallon tank was filled to capacity, that would create about 342 lbs additional weight to haul, which will put more stress on the engine, slow down speed, and increase fuel costs.  With the Aqua Whisper Mini, compact boaters will carry minimal weight, save space, and cruise without limits to any destination they wish. Featuring a simple interface, with push button operation, the Aqua Whisper Mini can be monitored via the control panel or remote (optional).  Featuring unlimited features at your control, Semi-Automatic Functions, 6 illuminated LED status indication lamps for system operation, an optional weekly automatic fresh water flush  and sequential starting of electric motors with manual override, this watermaker is an ideal for small power and sail boats. Technology:
