Perma Pure Showcases Conditioning Solutions for Continuous Emissions Monitoring at EPRI

Toms River, NJ (March 25, 2009) – Leading gas conditioning products manufacturer Perma Pure will display products for environmental monitoring at the EPRI CEM User Group Conference and Exhibit 2009, May 13-15 at the America’s Center (St, Louis, Mo.). The company will display its sample preparation technology for environmental analyzers and continuous emissions monitoring systems (CEMS), including the Baldwin™ Model 45 Dilution Probe. The dilution method is the dominant sample conditioning technology for CEMS in the coal-fired power industry. 


Perma Pure’s heated filter probes, Nafion® permeation dryers, filters, ammonia scrubbers, Baldwin brand chillers and complete sampling systems remove particulates, water and other harmful compounds from sample gas streams, protecting expensive analytical equipment.  The company’s Baldwin Model 45 Dilution Extraction Probe eliminates the need for conditioning systems and high-cost heated lines by reducing water vapor content in sample gas.  The out-of-stack system dilutes the sample gas with dry air by a ratio of between 25:1 and 250:1. 

The Model 45 features a unique hard metal critical orifice, instead of the glass capillary used in competitive products, for improved durability, repeatability, and cleaning during blowback.  The probe is housed in a rugged NEMA 4X enclosure for external mounting.
