Kokoelma: Make-up water

Make-up water: freshwater autonomy on board

Access to a reliable freshwater source is crucial for any long-distance navigation. Whether for hygiene, cooking, or general comfort, a well-sized and correctly installed watermaker radically transforms the onboard experience. Skysat, with its offshore racing experience, guides you in choosing and integrating a high-performance desalination system adapted to your specific needs. Discover the solutions we offer for guaranteed water autonomy.

Sizing your watermaker: the water/energy equation

Sizing a watermaker is not just about estimating daily water consumption. It is imperative to consider the energy efficiency of the unit, the desired production capacity, and the available installation space. Undersizing will lead to usage constraints and premature wear, while oversizing will result in unnecessary energy consumption.

• Low-consumption watermakers: Models optimized for use with limited energy sources (solar panels, hydrogenerators). Be sure to check the actual flow rate based on water temperature.
• Modular watermakers: Allow for future increases in production capacity by adding pump and membrane modules.
• High-pressure pumps: The heart of the system, it is crucial to choose a reliable pump adapted to the watermaker's operating pressure. Seal quality and maintenance are key elements.
• Pre-filters and activated carbon filters: Essential for protecting the reverse osmosis membrane and ensuring the quality of the produced water. Regular maintenance is essential.

Installation and maintenance: keys to increased longevity

Installing a watermaker requires rigorous planning and a thorough understanding of the boat's hydraulic and electrical constraints. Incorrect installation can lead to leaks, premature component corrosion, and a significant drop in performance. Regular maintenance is equally important to ensure the longevity and efficiency of the system.

• Positioning of pumps and membranes: Choose an accessible location for maintenance, protected from seawater spray and well-ventilated.
• Hydraulic connection: Use marine-grade hoses and fittings that are resistant to pressure and corrosion. Check for overly tight bends that could reduce flow.
• Regular rinsing: Perform freshwater rinses after each use to prevent membrane fouling.
• Chemical cleaning: Carry out periodic chemical cleaning (according to manufacturer recommendations) to remove organic and mineral deposits.

💡 Skysat's advice

Don't forget to include a conductivity meter (TDS meter) to monitor the quality of the water produced by your watermaker. High conductivity may indicate a membrane problem or contamination.
