Notes on operational criteria Particularly suitable for
stand-alone machines that
do not have an superordi‐
nate coolant circuit and
which do not have to fulfill
high requirements on the
stability of the coolant tem‐
perature.
This cooling type is partic‐
ularly suitable for systems
with existing central feed‐
back cooler. It does fulfill
high requirements on the
stability of the coolant tem‐
perature.
Particularly suitable for
high requirements on the
thermal stability e.g. for
high-precision applica‐
tions.
