4.1.3.3

Engineering the cooling circuit

Note
Observing the maximum permitted pressure
The maximum permitted pressure in the cooling circuit is 0.7 MPa (7 bar).
If a pump is deployed that produces a higher pressure, the produced pressure must be
limited by the plant with suitable measures (safety valve p ≤ 0.7 MPa, pressure control)
to the maximum permitted pressure.
● Specify the working pressure depending on the flow conditions in the supply and
return of the cooling circuit.
Select the smallest possible pressure difference between the supply and return so
that pumps with a flat characteristic curve can be used.
● Set the required coolant flow rate per time unit according to the technical data of the
equipment and motors.
Note
Install a backflush filter in the cooling circuit to prevent blockage and corrosion so that
any deposited material is flushed out.
