Commercial Marine Water Maker (5 Tons/Day) – Offshore Freshwater Generation

Commercial Marine Water Maker (5 Tons/Day) – Offshore Freshwater Generation

Marine Water Maker | 5 Ton/Day Marine Seawater Desalination Unit

I. Product Overview

This marine water maker utilizes core reverse osmosis (RO) seawater desalination technology and is custom-designed for various commercial vessels, workboats, and offshore platforms. The unit features an integrated design combining a pre-treatment system, high-pressure pump, RO membrane assembly, and automatic control system. Its robust structure is engineered to withstand the high-humidity, high-salinity, and corrosive environments typical of marine operations. It purifies seawater and brackish water, producing water that meets national standards for domestic drinking water (tap water).

The unit supports global multi-voltage inputs and comes pre-commissioned from the factory; it is ready for operation immediately upon connection to water and power supplies on board. It provides a stable and reliable source of domestic drinking water, meeting the crew's daily needs for drinking, cooking, and washing.

Note: The rated water output is a reference value based on standard operating conditions (water temperature 25°C, seawater TDS ≈ 35,000 ppm). Fluctuations in feed water temperature or seawater salinity may cause slight variations in output. III. Effluent Water Quality Specifications

The equipment utilizes high-precision reverse osmosis membranes to achieve efficient desalination, removing harmful substances such as salts, heavy metals, sediment, colloids, bacteria, microorganisms, and unpleasant odors from seawater:

1. Sensory characteristics: The effluent is clear and transparent, free from the salty or bitter taste of seawater, and has a pleasant flavor;
2. Physicochemical properties: Dissolved salt ions and heavy metals are removed, producing fresh water suitable for drinking and cooking;
3. Microbiological standards: Pathogenic bacteria are filtered out, meeting safety requirements for direct human consumption;
4. The effluent meets municipal tap water standards and can serve as the complete domestic water supply for the ship's crew.

IV. Core Product Advantages

1. Marine-specific design adapted for shipboard environments

With dimensions of 108×60×160 cm and a compact vertical structure, the unit is easy to position and secure within the ship's cabin. All components undergo anti-corrosion treatment (salt spray resistance) to withstand harsh, humid, and high-salinity marine environments, ensuring stable operation and vibration resistance.

2. Wide voltage compatibility for global marine power grids

Supports a wide voltage range (220–380–440V, 50–60Hz), making it compatible with the power systems of ships from various regions, including China, Southeast Asia, Europe, and the Americas—ideal for export and overseas marine projects. With a power rating of 2.2 kW and moderate energy consumption, it is suitable for long-term, continuous operation on board.

3. Stable daily output of 5 tons to meet vessel water needs

Produces 5,000 liters per day, sufficient for the daily domestic water needs of crews on small-to-medium commercial vessels and workboats. The system features pressure protection and high/low-pressure alarms, automatically shutting down during anomalies to minimize failure risks and ensure reliable, uninterrupted water supply at sea. 4. Integrated design for easy installation and maintenance

The system integrates pre-treatment, a high-pressure unit, reverse osmosis (RO) membrane modules, and an electrical control system, eliminating the need for on-site assembly. It features fully automatic operation, producing water immediately upon startup. Routine maintenance requires only the periodic replacement of pre-treatment filter cartridges; the system is user-friendly, allowing standard crew members to perform basic maintenance tasks.

5. Highly reliable RO purification ensuring safe water quality

Optimized for marine operating conditions, the system provides deep desalination, producing water that meets drinking water standards. Seawater-resistant components are used for piping and valves to extend the unit's service life and ensure a reliable, long-term water supply at sea.

V. Application Scenarios

- Drinking water supply for crews on commercial fishing vessels, workboats, and government/official vessels
- Water supply for offshore platforms and offshore engineering vessels
- Freshwater production equipment for ocean-going and coastal vessels
- Seawater desalination equipment for export vessels

VI. Product Summary

This 5-ton/day marine water maker is an integrated reverse osmosis seawater desalination system designed specifically for maritime use. It features wide-voltage compatibility, salt-spray and corrosion resistance, and fully automatic operation, converting seawater into fresh water that meets drinking water standards. With ample production capacity and ease of installation and maintenance, it serves as an ideal freshwater solution for various commercial and offshore vessels.
