Measuring gas cooler (option)

The SSM 6000 Classic analyzer version comes with a serial measuring-gas cooler. The SSM6000 LT is available with an optional
measuring-gas cooler.
Measuring-gas coolers are used in analyzer systems to process contaminated and humid measuring gases and to lower their dew
point. This reliably rules out the generation of condensate as well as the accumulation of dirt particles in the analyzer and other
system components. Adjusting a stable measuring-gas starting dew point avoids water vapor cross-sensitivity and volumetric errors.
The gas cooler works with an electronically controlled Peltier cooler. The design of the heat exchanger made of Duran glass favors
ideal flow conditions and ensures optimum lowering of the dew point to a stable value of 5°C.
A hose pump discharges the condensate produced into an external collecting tank. Status LEDs on the front panel indicate the
operating status of the gas processing unit. An alarm is generated when the set temperature is exceeded by 3°C.
The error LED can be activated for several reasons.
After power-on, the measuring-gas cooler is not yet ready for operation. The cooler should have reached its operating
-
temperature and the "error" LED should go off after around 15 minutes.
A measuring-gas cooler overload condition exists during operation as a result of the excessively high dew point of the inflowing
-
gas, or as a result an excessive volume flow or ambient temperature.
The device is defective. Contact the manufacturer of the device in such a case.
-
During the measuring process, the hose pump transports the condensate produced to the "condensate out" outlet of the device.
2.2.6

Housing rinsing

In connection with the option measuring cooler the SSM6000 has got available additionally comes with a fan unit that discharges the
heat of the measuring-gas cooler and rinses the housing with ambient air. The flow rate of the fan totals around 56 cubic meters per
hour, so that the generation of a flammable gas mixture within the analyzer is safely prevented.
In order to avoid dirt accumulation inside the device, a particle filter at the air intake opening on the right side panel of the analyzer
ensures reliable filtering of dust and other contaminants. The housing filter must be checked at process-dependent intervals and
must be replaced when visible contamination is found.

The status LEDs indicate the current operating status of the cooler. When lit, the individual
status LEDs have the following meanings.
cooler "o.k." The measuring-gas cooler is ready for operation. The actual temperature
of the cooler is within the pre-set temperature range of 5 ± 3°C.
cooler "active" The Peltier element is active. The frequency provides an indication of
the load exposure of the cooler.
cooler "error" The actual temperature of the cooler is outside the pre-set range of
5 ± 3°C.
