The Concept

Stella Watermakers are the result of many years of experience operating, servicing, selling and installing all brands and types of watermakers (reverse osmosis desalination plants). Proudly designed and manufactured in Australia, Stella Watermakers combine simplicity with quality components to create a reliable, easy to use system that offers real value for money. Whether you are a seasoned superyacht engineer or cruising yachty our modular watermakers are designed for easy installation, operation and maintenance.

The new Generation 3 Stella Watermaker



Stella manufactures 3 types of watermakers:

All Stella Watermakers are modular (separate components, not a large framed box) so they can be fitted wherever there is available space and use no electronics, just simple manual control valves.


Electric 240VAC240VAC Pump

For larger powerboats, yachts and catamarans with a suitable sized AC genset. Always the first option, easy installation and makes lots of water fast. You will need a minimum 3.5kva (continuously rated) genset to run our 240VAC electric unit. Output is 80, 160 or 210 litres per hour of water using 1, 2 or 3 standard membranes. Power usage (LP and HP pump) is approx. 12amps when running (without start-up load).


Engine DrivenEngine Driven Pump

For all vessels without a genset, but with an inboard engine. It’s a very efficient and reliable way of making plenty of water very quickly. You will need a suitable engine with room to fit an engine bracket and pulley system. We have some standard brackets available or custom fabrication is required. Output is 80, 160 or 240 litres per hour of water using 1, 2 or 3 standard membranes. Power usage is approx. 2HP draw from engine.


Electric 12VDC

For sailing yachts, catamarans and small powerboats. The last option if you don’t have a genset or suitable motor with room to mount a bracket. A smaller motor and high pressure pump means less water output but our 12 volt systems have been a huge sucess. You will need a good source of 12V power and you may need to run an engine while making water to top up batteries.


Stella Options


Auto Flush

Makes it easier to maintain your watermaker if you are not making water or on the boat every week to perform a manual flush. Optional automatic freshwater flushing system which includes a box with dual timer and solinoid valve to flush your system with water from your boats tank for a few minutes every 7 days. All watermaker membranes need to be fresh water flushed after each use and then every 7 days if not pickled for storage, to avoid damage to the membrane.


Spares KitSpares Kit

All the consumables you need for 6-12 months cruising (depending on usage). Includes: 3x 20 micron seawater filters, 3x 5 micron seawater filters, 1x 5 micron charcoal (carbon) filter, 1x 500g pickling solution (for membrane storage), 1x 1lt HP pump oil.


Stella Advantages


Simple manual operation, no electronics

We have made it simple to use. You don't have to study the manual to be able to operate our watermakers. We have Control Panelremoved the electronic automation which make watermakers difficult to use, unreliable and even harder to fix. Just two valves on the control panel and a knob to wind up the pressure. Comes with a laminated "Quick Start-Up Sheet" with step by step instructions so anyone can make water quickly.


Super performance and reliability

Our watermakers make a lot of water fast! 80-240 litres per hour with our AC and engine driven units. When it comes to making water "the quicker the better" so you don't have to do it every day or for long periods. With the simplicity, quality components and lack of electronics comes unequalled reliability, critical when cruising.


Quality 316 stainless steel components

From our high pressure pump to our membrane housing end caps and fittings, all metal components are 316 grade stainless steel (or Duplex), designed for a harsh marine environment. We appreciate quality and have sourced the best components from around the world for our watermakers. This combination of quality components and a simple design creates a very reliable, easy to use system.


Low maintenance and running costs

A simpler, better engineered watermaker with less components means less maintenance is required. Running costs are minimal, but will depend on how often it's used and how well it's maintained. Consumambles such as membranes, filters, pickling solution and pump oil are all standard items available from us or worldwide.


Modular design for easy installation

All Stella Watermakers are modular (seperate components not a large framed box) so can be fitted wherever there is available space. The Control Panel can be mounted with other components or remotely in a bathroom cabinet or cockpit locker.


 80-240 litres of water per hour (expandable)

Our AC and engine driven units make lots of water very quickly. Our standard high pressure pumps will run up to 3 membranes, so If your water requirements change you can always just add another membrane to increase water production.


No flashing lights or failing circuit boards

Fully automated watermakers use a multitude of electronics including a microprocessor, circuit boards, solinoid valves, timers, relays, pressure switches, led screens, flashing lights and salinity probes. Great when they work, but the cost goes up and reliability goes down! Any experienced cruiser knows that the simpler the equipment the better. Even seasoned superyacht engineers prefer our watermakers to others with all the "bells and whistles".


 No high maintenance energy recovery pumps

We don't use complicated energy recovery pumps with lots of o-rings and poppet valves that create more maintenance. We use industry standard 316 stainless steel triplex high pressure pumps with solid ceramic plungers, designed specifically for marine desalination. Parts and service for these pumps are available worldwide.

 End Plug

No cracking plastic membrane end plugs

We don't use plastic membrane housing end caps, they have a habit of cracking causing dangerous high pressure leaks. We use quality Duplex 2205 stainless steel end caps for high strength and corrosion resistance.


High Quality High pressure hoses

We don't use cheap and nasty high pressure hose's, they chafe easily from pump or engine vibration and can split or burst causing injury and damage. We use the highest quality hoses we can find with Quality 316 Stainless fittings. The hoses are protected with a anti-wear wrap to help protect and prolong the life of the hoses.


No proprietory components

We don't use special Stella manufactured components such as filters or membranes that force you to buy replacements from us and cost "an arm and a leg". We use industry standard components that you can easily find worldwide. If you are in a remote area we can ship parts fast if required or help you find them locally.


Best aftersales service and backup

We are not just a sales company, we design and manufacture our watermakers so can offer the best service and backup. We have a marine engineering division who services all brands of watermakers and can help with all troubleshooting queries.


Installation and servicing if requiredInstallation Manual

We don't just sell the equipment, we also offer a complete installation, commissioning and maintenance service via our marine engineering division Stella Marine if required. Our 30 page Installation & Operation Manual supplied with each watermaker provides simple step by step instructions with diagrams of all components making installation easy for the DIY boat owner, boat builder or contracted installer. The manual includes an easy to understand system flow diagram and detailed procedures for operation and maintenance of your watermaker.
