Comments on utilization
criteria
Particularly suitable for
stand-alone machines that
do not have an upstream
coolant circuit available and
do not have to fulfill high
requirements on the
stability of the coolant
temperature.
This cooling type is
particularly suitable for
systems with existing
central feedback cooler. It
does fulfill high require-
ments on the stability of the
coolant temperature.
Particularly suitable for high
requirements on the thermal
stability (high-precision
applications, for example).

Coolant lines
The coolant lines are a major part of the cooling system. They have a
great influence on the system´s operational safety and pressure drop.
The lines can be made up of hoses or pipes.
The continuous bending strain of the coolant lines must always be taken
into account when they are sized and selected.
