Perma Pure’s SDS-Series Boosts Existing Sample Conditioning Systems
Supplemental Drying System extends life and improves performance
Toms River, NJ (April 7, 2008) – Leading gas conditioning products manufacturer Perma Pure has introduced a cost effective product for extending the life and improving the performance of gas analysis equipment. The SDS™-Series Supplemental Drying System eliminates the formation of damaging acid mists and improves chiller performance in sample conditioning systems used in refineries, chemical plants and other environmental monitoring settings.
With the ability to lower a sample’s dew point from +4°C to below -15°C, the SDS-Series dryers can reduce total moisture content by an additional 80 percent. This dew point reduction eliminates the formation of acid mists, including downstream SO3 formation in high SO2 services. Acid mist corrosion is minimized, extending analyzer life and ensuring accuracy. Lower moisture content sample streams also improve the sensitivity of infrared measurements.
SDS-Series dryers are available for single (up to 10 lpm) or dual (up to 5 lpm each) samples streams. The dryers can be added on to compensate for undersized chillers, rather than replacing with new systems. They can also be used as the primary gas drying device, providing the sample is non-condensing at ambient temperature. The NEMA 12 rated enclosure is corrosion resistant for long service life.

Selectivity
Nafion is not only highly resistant to chemical attack, it also exhibits highly selective absorption and transfer of compounds. Most substances are retained quantitatively. Although they do not attack or damage the Nafion tubing, some polar organic substances are absorbed and consequently lost. Ammonia and amines are also absorbed and lost to some degree.
