The Series 500 Sample Coolers are moderate capacity thermoelectric coolers. They provide a self-regulated 4.0°C dew point gas sample. The 500 Series Coolers condense the water from a wet gas sample with minimal loss of the water soluble gas fraction. This results from the unique design of the heat exchangers. The separation occurs in the heat exchangers which have a highly polished cylindrical surface cooled by thermoelectric Peltier devices to the desired dew point temperature. These heat exchangers are available in a variety of materials including Stainless Steel, Kynar/Glass, and Hastelloy.

The 500 series coolers can be either panel or wall mounted and can contain one or more 5” heat exchangers. The number of heat exchangers and cooling scheme can be configured to satisfy your application need. The unit’s Peltier elements are cooled by heat sinks which are then cooled using either ambient air or a continuous supply of water.

The 500 Series Coolers can be easily integrated with other Universal Analyzers’ sample components including a condensate slip sensor with or without an integral condensate coalescing filter, peristaltic pump, sample pump, manual switches, external terminal strip, or PLC controlled sample handling systems, PLC controlled sample sequencers and a complete line of Stack Filter Probes. For high pressure applications, metal heat exchangers can be welded together as a single assembly. For special applications, stainless steel heat exchangers can be Silconert™ 2000 coated.
