Perma Pure is the only company that offers a complete range of sample conditioning products for virtually any application. We offer the following product lines:





Balwin Gas Coolers & Probes -Perma Pure acquired Balwin 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 Lakewood, 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 soluble 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.
