How does the iSave work?
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.
5.4 Temperature and corrosion
The chart below illustrates the corrosive
resistance of different types of stainless steel
related to NaCl concentration and temperature.
Depending on the NaCl concentration, the fluid
temperature must be between:
+2°C to +50°C (+35.6°F to 122°F).
In order to minimise the risk of crevice
corrosion, always flush the iSave accord-
ing to the specified start/stop procedure.
