Compressor
A hermetically sealed compressor is used in the refrigeration
unit. The compressor is equipped with overload protection
which trips on the compressor temperature and compressor
current consumption.
Condenser
Depending on the device type, an air-cooled or water-cooled
condenser is used in the refrigeration unit. In air-cooled con-
densers, the condensation heat is discharged to the environ-
ment. The fresh air is sucked in through the front of the device
using a fan, heated and discharged on the rear of the device.
In water-cooled condensers, the condensation heat is dis-
charged via cooling water.
Evaporator
In the internal bath, heat is discharged using a pipe coil evapo-
rator.
Technical information for the refrigeration unit can be
found in

Interfaces
Note the following:
The equipment connected to the low voltage inputs and out-
puts must have safe separation from dangerous voltages
according to DIN EN 61140 such as by double or reinforced
insulation according to DIN EN 60730-1 or DIN 60950-1.
Specific functions of the device such as the setpoint temperature
can be controlled with the RS232 interface using a PC. Thus,
custom programs for controlling the device can be developed.
Further information about the connection and configura-
tion can be found in
Changeover contact which switches in the event of a device fault.
For example, faults can be registered on a system.
Using the display, it can be set in which fault situations
a signal is output via the interface.
