Mini seawater desalinator introduced by Danfoss

Shown by Danfoss at the EuroMed exhibition in Jordan last November, the WaterCube 2 is a small domestic seawater reverse-osmosis desalination unit with a capacity of 5,300 L/d.

Intended for the large villa or small hotel, the unit takes up little more room than a fridge-freezer and will consume a mere 0.8 kW/h at full capacity, corresponding to <3.5 kWh/m³.

The WaterCube 2 is manufactured from high-quality components with all wetted parts made from duplex and super duplex steel, while all other steel parts use stainless steel 316. The high-pressure pump unit is Danfoss' own APP 1.0 and the membranes are custom-made by Hydranautics.

The footprint of only 540 x 500 mm ensures that the water purifier will fit in any environment and, with a height of 950 mm, is easily installed running off a 240 V grounded outlet (3 phases, 50 or 60 Hz).

The water purification process has been adjusted to minimise the load on the membranes significantly reducing the risk of fouling. Only 20% of the total volume of water passing through the machine is processed into drinking water. This way, the salt content in the brine is only marginally higher than that of the feedwater.
