Watermaker Buying Guide: Everything You Need to Know

When you’re venturing offshore, sailing long distances, or setting up a remote operation, access to clean water isn’t optional — it’s essential. If you’re considering buying a watermaker, you’re making a smart move toward self-sufficiency, convenience, and long-term cost savings.

But with so many options, how do you choose the right watermaker? In this guide, we’ll walk you through everything you need to know—from key features and sizing tips to maintenance, pricing, and the most trusted brands.

Why Choosing the Wrong Watermaker Can Cost You?

Buying a watermaker isn’t just a one-time purchase — it’s an investment in safety and comfort. Choosing the wrong system can lead to:

• Poor freshwater output
• Frequent maintenance issues
• Overconsumption of energy
• Wasted money on oversized or underperforming units

That’s why it’s crucial to understand what you need and how to evaluate your options before making a decision.

What to Consider When Buying a Watermaker?

Here are the most important factors to consider:

1. Water Production Capacity (Litres per Hour)

How much freshwater do you really need?

• Sailboats/Yachts: 30–80 LPH
• Liveaboards & Catamarans: 60–150 LPH
• Offshore Facilities: 200+ LPH
• Industrial/Containerized Plants: 1,000–10,000+ LPD

2. Power Source Compatibility

Your power supply determines what kind of watermaker you need:

• 12V/24V DC – Ideal for small vessels
• AC-powered – Suitable for larger yachts or commercial use
• Generator-powered – Common in offshore or remote operations
• Solar-ready options – For eco-friendly, off-grid setups

3. Ease of Maintenance & Accessibility

Look for systems with:

• Easy-to-access filters and membranes
• Clear control panels
• Automated flushing options
• Local service availability (like we offer across UAE & Oman)

4. Water Quality Monitoring

A quality watermaker should include or support:

• TDS meter / Ultrameter (e.g. Myron L)
• UV sterilizers
• Carbon post-filters

This ensures that you’re not just making water—but clean, drinkable water.

5. Build Materials

Choose corrosion-resistant materials like:

• 316L Stainless Steel for pumps and housings
• High-quality composite membranes
• Marine-grade tubing and fittings

6. Footprint and Installation Type

Options include:

• Compact under-sink units (for boats)
• Modular systems (ideal for space-limited installations)
• Skid-mounted & containerized RO systems (for remote or industrial sites)
