Only external applications with closed thermostatic circuits can be used
on the Integral devices. Direct temperature control of open baths is not
possible.
If the external temperature control volume exceeds the expansion volume in
the Integral, a return flow of heat transfer liquid from higher-level consumers
in the event of a fault or unintentional ventilation must be prevented with a
reverse flow protection device.
The external hydraulic circuit consists of the following components:
n
Hoses
n
external application
n
shut-off valves, if necessary
3.8 Rating label
The serial number of a LAUDA device is made up as follows:
n
the letter S,
n
the year of manufacture (is shown with two digits),
n
and a 7-digit number.
The figure shows an example of a rating label for a device without NRTL
certification.
The specifications on the rating label are described in more detail in the
following table. Certain specifications depend on the installed equipment.
