Thermal Capacity
The maximum thermal load supported by the
234B
depends on the ambient
temperature and cold plate temperature, as shown by the graph below.
The performance is based on an ambient temperature of 25°C, and actual
performance will be improved or degraded if the ambient temperature is lower or
higher, respectively.

When operating at temperatures that cause condensation (below the dew point),
the fixture must be purged with nitrogen to prevent the condensation of moisture
for two reasons:
1.
The energy required to condense the moisture from the air will
significantly degrade the performance of the fixture; and
2.
Condensation can lead to an accumulation of water inside the fixture,
which, over time, can cause corrosion and interfere with the proper
operation of the mount.
