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 Series 600 Mini-Coolers are our least expensive and most compact thermoelectric coolers providing a self-regulated 4.0°C dew point sample gas ready for analysis. This device can be either plate or wall mounted and can contain one or two 5” heat exchangers which are cooled passively (to ambient) and/or actively controlled using thermoelectric Peltier devices. The unit’s heat sinks can be cooled using either ambient air or a continuous supply of water. The unit provides a 0-1VDC signal output proportional to the sample temperature between 0-50°C. If the optional condensate slip sensor is included, two relay outputs are provided to indicate condensate slip. An externally mounted 12, 15, or 24VDC power supply is required and is offered as an accessory by Universal Analyzers. Wetted materials are 316 Stainless Steel, Glass/Kynar, Teflon Coated Stainless, Welded 316 Stainless Steel or Hastelloy C-276.

The Series 1000 Sample Coolers are our high 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 316 Stainless Steel, Kynar/Glass, and Hastelloy C-276. The 1000 series coolers can be either plate or wall 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 continuously flowing ambient.

The 1100 series vortex sample gas cooler chills the sample through the use of a Vortex Tube. Clean dry compressed air, preferably Instrument Air, supplied by the plant passes through a “generator” within the vortex tube which separates the high velocity molecules from the low velocity molecules to provide cold air within the sample cooler which removes heat from the sample. Three square feet of heat transfer surface, inside the cooler transmits the heat from the gas sample.

The Universal Analyzers 3000 series Thermoelectric Gas Cooler’s are widely used in both General Purpose and Electrically Hazardous Classified Areas such as those found at Refineries and Petrochemical plants. These gas coolers are used primarily in a gas analysis system to reduce a gas sample’s dew point providing a dry gas sample to one or more downstream gas analyzers. Its chasis design allows the 3000 Series to be optionally equipped with many sample system features that can be attached directly to the gas coolers enclosure. These features can include a sample pump, peristaltic pump, inline filter with condensate carry over sensor and a flow meter. With our FM/CSA/ATEX approvals, the series 3000 can be installed confidently worldwide.

The Model 270S is a Heated Stack Filter Assembly consisting of the filter body mounted in an aluminum protective housing. An optional blowback system is provided to allow a blowback to occur on command from a computer, data logger, PLC or external switch mounted in a safe area. A 125 watt heater is mounted on the outside of the filter cavity. The heater holds the temperature of the filter near 340°F (171°C). A bi-metallic thermal switch mounted to the filter body keeps the temperature from exceeding 350°F (177°C) by opening the circuit before that temperature. An optional independent thermocouple can be provided as a means to measure and transmit or record the temperature of the filter. A second thermal switch, set at 225°F (107°C), is provided to be used as an alarm contact if the temperature drops below the switch temperature.

Universal Analyzers offers a simple solution for most applications utilizing our 600 Series Sample Conditioning Panel. The 600 Series Cooler uses Peltier Elements to Thermo Electrically reduce the dew point of a gas sample which rapidly condenses and removes the water, providing a dry sample for the gas analyzers.

The 500 series portable sample chiller is a staple to the mobile stack testing and laboratory setting. In order to analyze stack gas or exhaust from any combustion process, a method to remove moisture from the sample without removing gas components of interest is a must. The Universal Analyzers Thermoelectric Sample Cooler, which derives its cooling from the Peltier Effect, is an ideal way to decrease the dew point of combustion gasses to a low dew point. For gas analyzers where water vapor interferes with the reading, a stable, repeatable, low dew point becomes a part of the gas analyzer`s performance specification. The Universal Analyzer Gas Sample Coolers prevent water condensation in sample pre-filters, sample pumps, and gas analyzers. The Universal Analyzers sample cooler provides this constant water concentration resulting in an accurate analysis of the components of interest.
