Frequently Asked Questions
What is a 1,000 GPD watermaker used for?
A 1,000 GPD watermaker suits large yachts, coastal villas, and small resorts — roughly the daily potable water for 30–45 people. It produces about 1,000 gallons (≈3,785 liters) of fresh water per day from seawater.
What power does it need?
It runs on AC or DC power and is solar- and generator-compatible, using a low-draw Danfoss APP high-pressure pump for efficient off-grid operation.
What membranes does it use?
It uses LG NanoH2O or Toray seawater RO membranes (>99.7% salt rejection) with marine-grade, corrosion-resistant construction.
