The Series 500 Sample Coolers are our 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 C276.
