Please contact Danfoss RO Solutions for further
information.
The diagram shows that the flow can be changed
by changing the rotation speed of the iSave. The
flow/rpm ratio is constant, but a required flow is
obtainable by changing the rotation speed to a
required value. The required rpm can be
determined on basis of below equation.
Please find the relevant parameters in above
table.
