Best Analog Modular Watermaker

Modular design — Allows components (membrane, pump, filters) to be placed separately; makes installation and maintenance easier in tight spaces.

Analog control interface — Manual gauges (pressure, flow), knob/valve controls rather than fully digital/automated systems, which can mean simpler servicing and lower cost.

Robust build and seawater compatibility — High‑pressure pump, seawater feed, corrosion‑resistant materials (stainless, brass) and saltwater safe filters/membranes.

Suitable production capacity — Match capacity (litres per hour or gallons per day) to your needs: small for boats or remote use, larger for base/marine use.

Energy & power requirements — Check voltage (12 V, 24 V, 110/220 V), power draw (kW or amps) and ensure your power source supports it.

Serviceability & parts availability — Membrane replacement, filters, high‑pressure pump repairs; choose a system with good support and global parts access.
