  • AquaStop, preventing flooding: Low sensitivity electronic control , blocking the system and warning the on board user about a possible water leak. Designed to prevent the system from stopping in case of humidity or condensation.
  • Water Quality Control: Press the front button to measure the conductivity of produced water.
  • Filter Change Warnings: A warning system embedded on the front panel through LEDs and acoustic media, informing the
    on board user when filters’ service life is about to expire.

Mineral Filter

Our mineral provided filter improves the quality of the clean produced onboard water, by adding the necessary health minerals for proper human development, such as Calcium, Magnesium, Sodium, Potassium and other ones readily found in many natural mineral waters. Mainly installed with reverse osmosis stems to complement their absolute filtration qualities. 

Cations in filtered water:
Ca2+: 34mg/l
Mg2+: 12mg/l
Na+: 22mg/l
K+: 8.5mg/l

Anions in filtered water:
CO32-: 10mg/l
SO42-: 0.3mg/l
Cl-: 0.8mg/l
F-: 0.06mg/l

Quick-Change Cartridge Reverse Osmosis System

Crystalia4Sea COMPACT RO Mineral Water Vessel Solution uses the most advanced water treatment technology taking in mind ship’s environment, by  “Reverse Osmosis” technology. Reverse Osmosis (RO) is recognised as one of the best available technologies for producing drinking water of best quality . It is also the same method used by many bottled water companies to make safe and water of great taste (except that terrestrial bottled water getting on ships has really many disadvantages, when compared to our system). No other drinking water treatment system can offer as much protection and reliability.

The newly designed quick-change reverse osmosis system is user-friendly, with design simplicity in mind. It requires no tools for filter changes. Use twist and quick-change cartridge design makes filter changes fast, clean and easy. No tools required for replacements. This space saving allows maximum use of ship’s under counter space.
