1000 Series Thermoelectric Gas Cooler

The Series 1000 Sample Coolers are our moderate capacity thermoelectric coolers. Providing a self-regulated 4.0°C dew point gas sample, the 1000 Series Coolers condense the water from a wet gas sample with a minimal loss of the water soluble gas fraction. This results from the unique design of the heat exchangers. The separation occurs in the impingers which have a highly polished cylindrical surface cooled by thermoelectric Peltier devices to the desired dew point temperature. These impingers are available in variety of materials including Stainless Steel, Kynar/Glass, and Hastelloy. The gas sample is brought to the bottom of the cylinder through an insulated tube and allowed to rise through a narrow annular area at a relatively high Reynolds number to insure the entire sample is influenced by the cold surface. The condensate flows down the cold polished surface in the form of a sheet (as opposed to droplets or the bubbling of the gas sample through the condensate) which minimizes the surface area in contact with the gas sample.

The 1000 series coolers can be either plate or panel mounted and can contain one or more 10” impingers. The number of impingers and the cooling scheme can be configured to satisfy a number of application requirements. The unit’s Peltier elements are cooled by heat sinks which are then cooled using either ambient air or a continuous supply of water.

Wetted materials are Stainless Steel, Glass/Kynar, Teflon Coated Stainless, or Hastelloy. The 1000 Series Coolers can be easily integrated with other Universal Analyzers supplied sample components including a water slip sensor with and without an integral water coalescing filter, peristaltic pump, sample pump, manual, external, or PLC controlled sample handling systems, PLC controlled sample sequencers and our complete line of Stack Filter Probes. For high pressure applications, metal impingers can be welded together as a single assembly. For special applications, stainless steel impingers can be Silconert 2000™ coated.
