Sea Recovery’s Ultra Whisper Watermaker features fully automatic operation. Energy efficient, quiet operation, and able to produce up to 200 – 600 GPD, this is an ideal desalinator for small power or sail boats.


The Sea Recovery Ultra Whisper has automatic features and worry-free operation.  Featuring automatic one-touch operation requires no pressure or operator adjustment and easy to use Start and Stop controls.  Self adjusts to feed water conditions. The Ultra Whisper is capable of producing 200 – 600 GPD (757 –  2,271 LPD), ideal for small power boats and sail boats.  This watermaker is energy efficient with low amperage per gallon of product water (25 GPH available in 24 VDC).  A lower power alternative, connects to either AC or DC power, the Ultra Whisper is engineered for boaters with limited electrical options.  Featuring a low powered Energy Transfer Device, the very quiet Ultra whisper is more efficient and requires less maintenance than before.  (Energy Transfer Device operates 759 hours between seal maintenance).  Noise Reduction Features include smooth running and extraordinarily quiet operation.  Vibration isolation mounts included Shipped from the factory ready to install and function, with no optional items required.  Includes a complete installation kit and a comprehensive and detailed Owner’s Operation and Maintenance Manual. Technology:

  • With the Ultra Whisper’s low power technology, boaters get more out of minimal power
  • The new Energy Transfer Device and the Ultra Whisper’s efficient functions are capable of reducing power consumption by up to 75%, giving the boater more out of the energy source and allowing worry-free travel
  • Automatic weekly fresh water flush included with system, if requested at the time of the order


  • Hour Meter for keeping accurate ship’s logs & schedule preventative maintenance
  • Solid state electronic flow meters for visual monitoring of the product water and feed water flow used to calculate production rates of the system
  • Exclusive Solid Salinity Meter shows actual product water quality, an essential tool for product water monitoring
  • Product water quality is displayed in bar graph format with 10 additional LEDs
  • Six illuminated LED status indication lamps showing the system operation status
  • Fault LED indication is provided for easy diagnosis of required maintenance
