Ordering Information for S Series Seawater Desalination RO Systems

Notes and Voltage/ Ordering Information

• All dimensions and weights are approximate.
• Based on 35,000 ppm seawater at 77°F (25°C). Recovery in the range of 10-40% depending on the system size.
• Operating pressure 800-1000 psi (57-71 kg/cm²).
• Seawater intake and supply pump to bring water to the system are not included. Beach well intake recommended.

Please add our voltage codes to the end of the model number when ordering:

Example: S-14A-236 = 220/230v / 3 ph / 60 hz
