The new compact HP SCA DOUBLE series of desalinators were shown at METSTRADE 2024 for the first time.
The new series is automated with a RP Tronic system eliminating the need for continuous pressure adjustments in the engine room to adapt to fluctuations in salinity and water temperature.
The series also performs an effective rinse at the end of the cycle with the valve fully open, making it unnecessary to chemically wash the membranes to remove accumulated salt.
“For automatic to really mean automatic, a number of careful arrangements are necessary, including in the installation phase: with the new HP SCA DOUBLE series we believe we have provided the answer that shipyards and shipowners were expecting,” explained Gianni Zucco, co-founder of HP Watermakers.
“Specifically, the innovation consists in the decision to remove the low-pressure pumps, the ones that bring seawater to the desalination unit, from the frame, reducing the footprint of the current SC Double series by 33%.

“We have moved them close to the seawater inlets, making the desalination plant’s seawater supply much more fluid.”
Moving the low-pressure pumps has also allowed the width of the HP SCA DOUBLE series box to be reduced from 1,100mm to 800mm, with no changes in height and depth (590 and 480mm).
The HP SCA DOUBLE series consists of two independent watermakers, set up in the same frame, and has been designed to optimise on-board energy usage and, at the same time, satisfy peak drinking water demand.
The HP SCA DOUBLE series consists of five models with a freshwater output between 240 l/h and 1,200 l/h.
The 440 unit has the membranes installed inside the box.
In the other models, they are separate, allowing shipyards to install them where they deem most appropriate.
