A new series of watermakers

The WM series comprises two product lines:

The WM-E line which comprises RO units with energy recovery systems

The WM-B line which comprises RO units without energy recovery systems

Brief introduction to the difference between systems with and without energy recovery:

  • 18-30% of the supplied Seawater to a unit is converted into freshwater at a 70 bar / 1000PSI. 
  • With a recovery of say 25% the remaining 75% of the seawater is returned back to the sea at 70 bar / 1000 PSI…..this is proportional a lot of “wasted energy”!
  • The energy recovery device is converting this “wasted energy” back into the system reducing the overall power consumption
  • The energy recovery device also insures that the units are fully automatic and there is no need for any adjustments at all!

 Applications include:

  • private homes
  • real estate developments
  • small to medium sized hotels and resorts
  • decentralized drinking water to small communities
  • aquaculture industries
  • government institutions
  • various on- and offshore installations

As opposed to all other RO units the Aqsep watermakers are comfortable with any salt content in the water, from sea water to lightly brackish water.
