Frequently Asked Questions

A watermaker desalinates seawater, usually using a reverse osmosis process. This process separates the salt and other contaminants from seawater under high pressure, producing clean fresh water.

Production capacity depends on the model. Seacraft Watermakers offers a range starting from the SCW-30 at 30 liters/hour for small yachts, up to 500–1,000 liters/hour for large commercial vessels. Choosing the right capacity depends on your crew size, shower and galley usage, voyage duration, and daily operating hours. Contact us for a personalized recommendation.

No. Seacraft Watermakers devices are designed for fully automatic operation with a digital control panel, automatic flush system, and visual/audible alarm support. You can start, pause, and stop the system with just a few button presses. During initial installation, our technical team walks you through operation on-site.

Price varies depending on the model, capacity, and optional features. The Seacraft Watermakers range covers systems from compact small-boat models to large commercial installations. For a quote tailored to your vessel and requirements, please contact us.

No, Watermakers are used not only for marine, but also in land-based facilities. Especially in areas where inter-regional transportation and fresh water supply are difficult, Watermakers can be used to increase water resources.

Power requirements depend on the model:

• SCW-30 and SCW-50 (12V DC): Run directly from the boat's service battery or solar panels — no generator required. Low current draw with quiet, efficient operation.
• SCW-100 INV PRO: Compatible with both 12V DC and 230V AC power sources via built-in inverter technology.
• SCW-150 and above: Require 230V AC power (generator or shore power).
• SCW-500 and SCW-1000: Require three-phase 380V/50Hz AC; designed for commercial and industrial marine applications.

Yes. Key maintenance tasks include:

• Filter replacement: Pre-filters should be changed regularly — a clogged filter reduces output and shortens membrane life.
• Membrane flushing: Flush the system with fresh water after each use or every 24 hours to prevent salt buildup inside the membranes.
• Winterization: If the system will not be used for more than 4 weeks, a winterization procedure must be performed to prevent bacterial growth in the membranes.
• Pump oil change: Change the high-pressure pump oil every 250 hours of operation.

Regular maintenance preserves production capacity, extends membrane life, and ensures reliable long-term operation.

Key factors to consider when selecting a marine watermaker:

• Capacity: Calculate your crew's daily water needs (drinking, cooking, showers). For small boats, the SCW-30 or SCW-50 series are ideal; for medium yachts, consider the SCW-100 or SCW-150; for large gulets and commercial vessels, the SCW-350 and above.
• Power source: If you have no generator, 12V DC models (SCW-30, SCW-50) are compatible with solar panels or battery banks.
• Installation space: Choose compact if you have an open, linear installation area; choose modular if space is tight or fragmented.
• After-sales support: Spare part availability and technical service access are critical for long-term reliability.

Yes. Reverse osmosis technology blocks salt, bacteria, viruses, and heavy metals from passing through the membrane. The output meets World Health Organization (WHO) drinking water standards. Seacraft Watermakers devices operate on the same principle, and the water produced is safe for drinking, cooking, and personal use.

Two mounting options are available:

• Compact model: All components (pump, membrane, control panel) are integrated into a single enclosure. Installed as one unit; quick to set up and easy to maintain. Ideal for boats with an open, linear installation space.
• Modular model: The pump unit and membrane unit are mounted independently. Allows components to be placed in separate locations — perfect for tight, divided, or irregular engine rooms. Also offers easier service access.

Both options deliver identical production capacity; the difference is only in how they are installed.

Yes. The SCW-30 and SCW-50 models run on 12V DC power and can be connected directly to solar panels or your boat's service battery — no generator required. This makes them ideal for eco-conscious sailors who want to produce freshwater silently and sustainably. For solar panel sizing and battery planning guidance, our technical team is available to assist.

With proper maintenance, the TORAY and FILMTEC membranes used in Seacraft Watermakers devices have an expected service life of approximately 2-3 years. Key factors that affect membrane lifespan include:

• Regular flushing with fresh water after each use
• Correct winterization when the system is not in use for extended periods
• Timely pre-filter replacements
• Prolonged continuous operation in high-salinity or warm water conditions

Our devices are manufactured in accordance with CE European Standards and ISO-9001 quality standards.
