NOTICE
Damage to the dry ice condenser due to cryogenic
substances.
ð Carry out a visual inspection prior to each use. Glass sur-
faces must be free from damage, ruptures, cracks and
scratches.
ð Only loosely lay on the cover of the dry ice condenser, thus
ensuring pressure equalization between the coolant and the
atmosphere.
ð The coolant can escape from the chiller unexpectedly, e.g.,
in case of high gas volume.
Cooling with dry ice condenser
The dry ice condenser does not have a coolant connection. For
cooling, the dry ice chiller is filled with a refrigerant mixture.
These refrigerant mixtures consist of cold to cryogenic media
and a liquid for better cooling transfer.
