Aqua Whisper Mini

Aqua Whisper Mini Banner


    Sea Recovery has added a new modular configuration to the Aqua Whisper Mini series of watermakers. The new Aqua Whisper Mini modular is engineered to fit anywhere, in the tightest of spaces, and provides easy access to main components. The Aqua Mini series of watermakers is engineered to fit anywhere and gives you the choice to produce more fresh water while keeping the same small footprint. Measuring at about 2 – 3 cubic feet, sail and small power boaters have the opportunity and the convenience of owning a Sea Recovery watermaker without the space restrictions. Producing from 7, 15, 23 or 31 gallons of fresh water per hour, the Aqua Whisper Mini series of watermakers are the perfect seaworthy companion for the solo cruiser.

    Replacement Filters
    Whether for the pre-filtration stage or post treatment stage, the Sea Recovery R.O. Filter Elements are an essential part in proper system performance.

    Membrane Elements
    Membrane Element Storage
    These chemicals inhibit bacterial growth while maintaining the high flux and salt rejection of the R.O. Membrane Element.
    Membrane Element Cleaning Compound #1 (SRC MCC-1) is an alkaline cleaner designed to clean biological fouling and slight oil fouling from the R.O. membrane element.

    Membrane Element Cleaning Compound #2 (SRC MCC-2) is an acid cleaner designed to clean calcium carbonate and other mineral deposits from the R.O. membrane element.

    Membrane Element Cleaning Compound #3 (SRC MCC-3) is used for iron fouling. If the system’s R.O. membrane element is fouled with rust from iron piping, then SRC CC-3 may be used for effective removal of light or moderate rust fouling.
