Delivery incl. all components for easy installation.

Board outlets, sea valve and connection cable are to be provided on board.


Watermaker DD 500, a proven desalinator for the two-person crew, driven by a 12 V or 24 V DC motor. The direct drive via a flexible coupling ensures smooth and maintenance-free operation.

DC watermaker usually are the only option when there is no generator on board to power a desalinator with 1 or 3 phase AC (115 V- 440 V).

When deciding on a watermaker, keep in mind that doubling the fresh water output will result in halving the runing time. This inevitably leads to a doubling of the lifetime of the watermaker. However, the energy consumption of the watermaker is then also about twice as high due to the physics involved.

After customer experience and also own experience the desire for a larger Watermaker, already after short habituation to the luxury of chlorine-free and good fresh water is very often present. The advantages of having a watermaker on board are very diverse, especially in southern countries, and are often considered a necessity by many yachties.
