Further optional components
Distribution components
Coolant temperature controllers
Flow monitors
A message is output when the flow drops below a selectable
minimum flow quantity.
Level monitors
Chiefly minimum-maximum level monitor to check the coolant level in
the coolant container
Overflow valves
Safety valves
Opens a connection between the coolant inlet and the contained
when a certain pressure is reached
Coolant filters (100 µm)
Coolant heaters
To provide coolant of a correct temperature, in particular for coolant
temperature control
Restrictors and shut-off valves
Circuit types
The two possible ways of connecting hydraulic components
(series/parallel connection) show significant differences with respect to:
Pressure drop of the entire cooling system
Capacity of the coolant pump
Temperature level and controllability of the individual components
that are to be cooled

Fig. 9-20: Parallel connection of liquid-cooled drive components
The parallel connection is characterized by nodes in the hydraulic
system. The sum of the coolant streams flowing into a node is equal to
the sum of the coolant streams flowing out of this node. Between two
nodes, the pressure difference (pressure drop) is the same for all
intermediate cooling system branches.
