Working Conditions




Treatment ability and working pressure of the RO system are dependent on feed water quality.

Nominal permeate rate listed at temperature 25℃，Permeate rate can be reduced by up to 20% as temperature drops.

Naida Seawater RO systems are available in a variety of voltages.Please select the desired voltage code as below.

The three-digit code will be added to the end of the Seawater RO system Model number.

Example：SW-S-400(116)=110V/1Ph/60Hz.

Voltage Codes(available for all models) :

-116 =110V/1Ph/60Hz

-216=220V/1Ph/60Hz

-215=220V/1Ph/50Hz

-235=220V/3Ph/50Hz  

-236=220V/3Ph/60Hz  

-335=380V-420V/3Ph/50Hz  

Remark:All weight and dimensions are approximate.Other custom designs are available upon request.
