Another observation from the datasheet: this seems extremely energy-intensive, even compared to desalination. Modern desalination ranges from about 3 kWh/meter^3 (reverse osmosis) to 13-25 kWh/meter^3 (multistage flash distillation) [1] [electricity-equivalent kWh]. The wind turbine's spec sheet says it has two scroll-compressors rated 30 kW combined. I'm not sure about the capacity factor these compressors operate at (no data given), but if it's basically that of the wind turbine itself (should be about ~20%), that's ~140 kWh (mechanical energy)/day for 1 meter^3/day water, or 140 kWh per m^3. Triple that for a desert zone (same energy, one-third the output).
