Dessalator D30 Freedom

DC Watermaker
30 - 38 lph


Call for our current price

Ideal for smaller yachts and boats where water requirements are modest and DC power is available via the engine alternator. Compact individual components can be located in small voids so you don't have to use precious locker space. Whether for showering, washing up or even rinsing off your 'oilies', you can enjoy pure water on tap, every day and now your plans can include those far flung destinations.

Note: Watermaker outputs vary dependent on water temperature and salinity.

Note: the image of the major parts package is that of the D60. The D30 package differs only in that the membrane stack has one tube not two.

Please call us on 01794 523900 for details of our special offers.

Additional Information


As with all Dessalator ranges, your Freedom watermaker is supplied as a complete system including:

Automatic fresh water rinsing - keeps your watermaker fresh and clean, prolonging the life of the membranes: it also back-flushes the pre-filter.

Manual fresh water rinsing - a simple turn of a lever means you can give your watermaker an extra rinse when leaving your boat and when returning after a longer period, keeping your membranes fresh, clean and ready to make pure water.

Automatic transfer to tank of fresh product water simplifies operation, letting you relax whilst your tanks are replenished.

Easy to operate - the control panel has a simple on/off, pressure regulator and status lights to indicate clearly what is happening.

Flowmeter - easily monitor the rate of production.

Hourmeter keeps track of hours run to help analyse performance and establish need for service.

Engineered for long life - for ultimate reliability and low maintenance all Dessalator watermakers are over-engineered.

CAT high pressure pumps - the best; for reliability and peace of mind (we have never had one fail!).

Salinity detector - for prompt fully automatic transfer of water to tank and automatic rejection of salty product water if a problem arises.

Automatic shutdown with alarm light if the pressure gets too high and if there is no water flow (pressure too low),

Carbon fibre high pressure membrane tubes avoid issues with corrosion and are strong and light - maximising long life.

High quality Filmtec ® by Dow Corning membranes for long life, increased output and greater resistance to chlorine.

Laser cut stainless steel chassis with anti-vibration mounts for durability and quiet operation.

Designed with extensive periods of operation by the long distance sailor in mind; all Dessalator machines, whilst being fully automatic, have full manual override facility so that you can continue to make water provided you have power. At the other end of the spectrum, they can be linked to a centralised management system e.g. a 'glass bridge' computer system via a serial link.
