The Sea Recovery Aqua Whisper Mini Series are the smallest line of watermakers. The low-hassle Aqua Whisper Mini is engineered to fit anywhere,  so sail and small power boaters have the opportunity and the convenience of a Sea Recovery watermaker without space restrictions. The Aqua Whisper Mini has a 20 gallon tank and is able to produce between 170 – 750 GPD (644 – 2,839 LPD) in capacity, therefore is this desalinator the perfect seaworthy companion for the solo cruiser.

With the Aqua Whisper Mini, compact boaters carry minimal weight, save space, and cruise without limits to any destination they wish. Weighing at most 130 lbs, the Aqua Whisper Mini is also more convenient than hauling around a full water tank which consequently adds about 8 pounds per gallon to your boat. To illustrate, if a 34 gallon tank is filled to capacity, it adds 342 lbs additional weight to haul, this puts more stress on your engine, slow down speed which as a result increase fuel costs.

Featuring a simple interface, with push button operation, the Aqua Whisper Mini can be monitored via the control panel or remote control (optional). Featuring unlimited features at your control, Semi-Automatic Functions, 6 illuminated LED status indication lamps for system operation, furthermore an optional weekly automatic fresh water flush and sequential starting of electric motors with manual override.
