The status output can be used, for example, to control the
sample gas pump, allowing the gas flow to be enabled only
once the permissible cooling range has been reached, or to
switch off the pump in the event of a humidity sensor alarm.
The separated condensate can be discharged via connected
condensate pumps or attached automatic condensate drains.
Furthermore, fine filters can be used, into which humidity
sensors can optionally be integrated.
The glass dome allows the dirt level of the filter element to
easily be determined.
The humidity sensor can be easily removed. This may be ne-
cessary if, due to a fault, a breakthrough of condensate into
the cooler occurs which can no longer be removed by the con-
densate pump or automatic condensate drain.
