Watermakers / AC Systems
240/120V AC watermaker
For boats with a 4.5kW or larger generator. A high-volume, high-pressure pump makes water quickly, so run times stay short and your membranes last longer.
From NZ$13,090 + GST
Key Advantages
High-volume water for generator-equipped boats.
Install
Easiest installation
Direct-coupled AC models are the most straightforward systems in our range to install.
Output
Scalable output
The high-flow pump grows with your needs. Start at 80 litres per hour and add membranes to reach 160 or 240.
Longevity
Membrane health
Runs at the ideal recovery ratio, which means longer service intervals and a longer life for the whole system.
