Romer's Solar and Wind Powered Series are designed for off-grid areas using a dedicated drive-control desalination system that run without batteries, intermittent desalination takes place when there is sunlight or wind.

Typical installations are restaurants and tourist stations located on the coast or an island which is off-grid.

Two Level Production Water(TLPW):
90% Permeate TDS is lower 700PPM,10% Permeate TDS is lower than 50PPM.

No Battery Design(NBD):
Desalination process using reverse osmosis membrane technology, with no phase change or modularization. It is a simple process with easy operation on small volume, low energy consumption. Using dedicated drive-control desalination, the system runs without batteries and intermittent desalination takes place when there is sunlight or wind.

Saving Design(SD):
Turbo collector recovers 35% of energy from waste water emission. Top-level pressure converter (energy recovery equipment) recycles 60% energy from emissions.
