Depending on the NaCl concentration, the fluid
temperature must be between:
+2 °C y 50 °C (35,6 °F y 122°F).

5.7 How does the iSave work?

Figure 5.1 shows a section view of the iSave.
The iSave consists of a rotating isobargic
pressure exchanger and a positive
displacement pump, also called booster
pump. The rotation speed of the pressure
exchanger and the pump is exactly the
same, as they are driven by the same electric
motor.
