The same proven Scout and Nomad components, broken into four pre-assembled modules. Mount them, plug them together, and run the system from a remote panel. No fabrication. No guesswork.
Download BrochureLEDI Modular is the right choice when you want the watermaker installed out of sight, controlled from a practical onboard location, and matched to your boat's real daily water demand.
High-pressure plumbing, electrical interfaces, and control logic are all standardised — so competent owners can install a Modular kit themselves, without sacrificing reliability or serviceability.
Compact, manageable, easy to position in tight spaces. Mount them, plug them together, and connect to your boat.
Standardised high-pressure plumbing, electrical interfaces and control logic. No bracket-making, no guesswork on routing.
Self-priming intake, mechanical pressure protection, automatic flushing and continuous water-quality monitoring all built in.
Diagram-based install documentation, plus Australian phone support if you hit a tricky run.
Each module ships pre-assembled, pressure-tested and ready to mount. Click any module for the engineering rationale.
Continuous-duty brushless feed pump paired with the right 316 stainless high-pressure plunger pump for your output band.
Larger 2.5"×10" filter bank with auto-flush controller. Longer service intervals than the portable units, plus protected storage.
Configured around both space and output — five layouts so the system fits the room you actually have.
Powder-coated aluminium panel, surface or flush mount. Run the watermaker from where it actually makes sense onboard.
Programmable timer flushes the membrane after every run. Greatly extends life and reduces maintenance when the system isn't in regular use.
Ultra-compact, fully 316 stainless plunger pumps. Chosen for efficiency, durability and long service life in continuous-duty desalination.
20 + 5 µm pleated cartridges and a 5 µm carbon block. Protects the membrane, reduces fouling and improves long-term reliability.
Pressure gauges, flow meter, TDS, switches and selector — all on one panel. Install hardware out of sight, control from where you live.
Adds a final UV polish stage for biological safety in stored potable water. LED-based — no lamp to ever change.
Stainless steel pressure relief valve for mechanical protection against overpressure and operator error.
Total dissolved solids meter on the panel. Immediate confirmation that product water is within spec — every minute of every run.
Confirms the system is producing the flow it should — and makes fault diagnosis straightforward when something drifts.
Six output bands and two voltages. Match the kit to your boat's real daily water demand instead of running a single oversized config.
Open the crate, mount four modules, route hoses, run power. The interface points below are deliberately standard so you can plumb into existing seacocks and freshwater supply.
The six connection points to your boat — published openly so you can plan the install before the crate even ships.
The order is deliberate. Mount first so hoses and cables sit naturally, then plumb, then power, then commission. A weekend job for a competent owner.
Position pump module, prefilter module, membrane housing and remote panel using the install drawing. All within 1.5 m of each other.
Seacock to inlet, freshwater feed to flush port, brine and product water out. Pushfit and BSP — no high-pressure fabrication.
Anderson plug to the pump module for standard kits, or 70 A DC cable for CATPUMP configurations. Fuse and switch supplied.
Open the seacock, prime through the carbon block, set auto-flush timer, switch to RUN at the panel. Watch TDS settle below 500 ppm.
Switch tabs for each output band. Need a custom layout? Talk to LEDI before ordering.

Email LEDI →Use a practical guide of 5 to 10 litres per person per day for drinking and cooking, plus extra for washing. 10 to 20 LPH is right for lighter use and smaller crews. 20 to 40 LPH is the common sweet spot for liveaboard cruising. 40 LPH and above suits heavier daily demand or larger tanks.
Choose the closest output and voltage, then call us to confirm before ordering.
Yes — that's exactly what the kit is engineered for. Modules are pre-assembled with all high-pressure plumbing, electrical interfaces and control logic standardised. You mount four modules, plug them together, and connect five interface points to your boat.
Detailed install drawings are included. Australian-based phone support is available if you hit a tricky run.
For flow rates up to 20 LPH, LEDI uses the 316 stainless Pumptec 107SS plunger pump. For higher-output configurations we step up to the 316 stainless CATPUMP 2SFSEEL platform — capable of up to 160 LPH. All CATPUMP-based systems include integrated pressure-switch protection against dry running, which makes them the stronger choice when output and duty cycle increase.
The prefilter module includes a programmable timer and a hose barb to your boat's pressurised freshwater supply. After every run, the system pulls clean water through the carbon block and across the membrane to remove residual seawater. Greatly extends membrane life when the system isn't in regular use.
Modular kits are built to order on the Gold Coast. LEDI aims to ship within 2–3 weeks depending on configuration and build queue. If you have a hard deadline (haul-out, delivery trip, refit), call us before ordering and we'll let you know what's realistic.
Replace pleated prefilters every 3–6 months and the carbon block every 6 months — all standard 2.5"×10" cartridges, available from any RO supplier. Membranes last 2–3 years with proper auto-flush. The HP pump uses a service kit that LEDI keeps in stock.
Out of sight in the machinery space, controlled from a panel by the helm. The same DNA as Scout and Nomad — purpose-shaped for a clean fit-out.
Send a photo of your machinery space and tell us your crew size, tank volume and runtime. We'll spec the layout, voltage and output band before you order.
