The gas sample is first pulled through a sample probe, which usually contains a heated filter, and then through a heated sample line, which keeps the sample above its dew point. The 500 Series Cooler then condenses water out of the sample, which lowers the dew point to 5°C (41°F).

The result is an assembly with superior heat exhausting capabilities under high ambient temperature conditions. The 500 Series Coolers have a digital display for front panel indication of the operating temperature of each of the heat transfer blocks (switch selectable) in degrees Centigrade. Two internal jumpers at the top of the control circuit board within the enclosure can be moved to change the indicated temperature to read out in degrees Fahrenheit.

Description and Principle of Operation DESCRIPTION A gas sample pump may be provided as part of the sampling system. If the pump is placed ahead of the sample cooler, it should be provided with a heated head to avoid the condensation of water vapor. If the sample pump is placed after the sample cooler, drawing the sample through the cooler, the sample has been dried, and a standard, non-heated pump may be used.
Installation The 500 Series Thermoelectric Gas Coolers are best suited for air conditioned environments. Each unit dissipates heat, and the surrounding area must be well ventilated to provide adequate cooling. The cooler should be located away from other heat sources. If located inside an enclosure, outside air should be ducted directly onto the heat sink, and thermostatically controlled fans and vents should be utilized.
Shutdown Stop sample gas flow to the Universal Analyzers 500 Series Thermoelectric Gas Cooler by turning off the sample pump. Allow the drain pump to run for several minutes to remove any remaining condensate from the heat exchangers. After all condensate has been drained, turn off power to the cooler.
Before performing any maintenance on the 500 Series Thermoelectric Gas Cooler, ensure that all plant safety procedures are followed. The 500 Series Cooler is designed for maintenance free operation, but if any is required, ensure power has been removed before maintenance is performed.
Troubleshooting The following table should give an overview of possible errors and an instruction to check and to repair them (is not valid for the starting-up period of cooler). Error Possible reason Check/Repair The presence of water Overloading of the refrigeration capacity of the cooler due to too much water vapor or too great a sample flow rate...
