Depending on the NaCl concentration, the fluid
temperature must be between:
+2°C to +50°C (+35.6°F to 122°F).

The figure below shows a section view of the
iSave.
The iSave consists of a rotating isobaric 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.
