Stack Testing, CEMS and Source Emissions Monitoring

Perma Pure offers the most complete range of sample conditioning technology for CEMS and process measurements. The Baldwin™ Series line of thermoelectric coolers and probes is well known for quality, reliability and value. Some applications require removal of moisture in vapor phase to avoid unintended loss of analytes which dissolve in condensing water. Nafion™ membrane drying systems by Perma Pure offer this alternative sample conditioning technology. We offer the following product lines:

Baldwin Gas Coolers & Probes -Perma Pure acquired Baldwin Environmental Systems, a well-respected respected manufacturer of traditional gas cooler and related gas sample conditioning equipment in 2006. Since the acquisition, we have made many quality improvements, updated the product line and brought it into our ISO 9001 approved production facility in Tome River, NJ. We offer a full line of proven, high quality Gas Sample Coolers, Dilution Probes and related Sample Conditioning products and accessories.

Nafion™-Based Gas Sample Conditioning Systems– While traditional gas sample coolers will reduce unwanted moisture from many sample gas streams, certain applications will require the membrane drying power of Nafion™ to properly remove enough water vapor without dissolving water soluble acid gases. In many of today’s applications, environmental agencies are permitting very low levels of pollutants and the only way these can be measured accurately is by conditioning the gas sample with a Perma Pure Nafion™ based Sample Conditioning System.

Applications best suited to Nafion™ include:

  • Locations with low permitted levels of H2S, HCl, NOx and SOx
  • High moisture content (> 30%) gas streams
  • Water soluable analytes such as H2S, HCl, NOx and SOx
  • Very low dew points (-10 C) required for infra-red analyzers and high SO2 applications

Filters, Scrubbers and Accessories – Perma Pure offers Ammonia and Acid Scrubbers, High Capacity Filters, Heatless Dryers and a range of accessories to improve your sample conditioning. We also offer these products to OEM manufacturers of analyzers and system integrators on a volume basis.

Portable Equipment – Perma Pure has developed a range of unique portable equipment, from gas coolers, zero air generators to full sampling systems designed to make your life easier.
