Cooling circuit (Design and Maintenance)
Page 13 shows you schemes of the cooling circuit.
The cooling unit operates largely maintenance free. If the ambient of the Immersion
Coolers is dust-laden we recommend to clean the condenser of the cooling unit every 4 to
6 months. For this reason blow compressed air into the venting slots for some minutes.
The motor of the compressor is secured against overloading by a double acting bimetal
switch (KLIXON). This switched responds to the temperature of the casing and additionally
to the current consumption of the compressor motor. If ventilation is insufficient
temperature of the housing increases andthen the condensation pressure. Both reults in an
excessive overloading of the motor shich is now switched off. It is switched on again
automatically as soon as the housing has cooled down. For quick cooling the cooling unit
can also be started at temperatures around 100°C. However it is possible that at higher
temperatures the KLIXON switches of the compressor several times.

Maintenance
LAUDA Immersion Coolers are designed for coninuous operation and do not require
maintenance routine.
8.1 Note on repair and disposal
The refrigeration circuit is filled with a CFC-free refrigerant. Type and charging quantity are
