 Oxygen, water vapor, and other trace gases permeate the membrane fiber and are discharged through gasaircompressorpressureswitch a permeate port. Nitrogen stays within the hollow fibers and flows through an outlet port.Balston PSA nitrogen generators produce up to 99.95% pure, compressed nitrogen at dewpoints to -40[degrees]F from nearly any compressed-air supply. The generators continually transform gasaircompressorpressureswitch air into nitrogen at safe, regulated pressures without operator attention.PSA generators use a combination of filtration and PSA technologies to create nitrogen.Compressed air is prefiltered to remove all contaminants down to 0.1 micron. The gas separation process preferentially adsorbs oxygen over nitrogen using carbon-molecular sieve (CMS). At high pressures, the CMS has a greater affinity for oxygen, carbon dioxide, and water vapor than it does at low pressures. By raising and lowering pressure within the CMS bed, all contaminants are captured and released, leaving the CMS unchanged. This process lets nitrogen pass through. Depressurizing the CMS releases adsorbed oxygen and other contaminant gases to the atmosphere. HYDROGEN GENERATORSGenerators can also make hydrogen using one of two basic technologies: proton-exchange membranes (PEM), and palladium membranes. Hydrogen gas generators are most often used in gas chromatographs and in labs for hydrogenation reactions and engine-emission analysis. PEM systems from Parker produce flows from 90 to 1200 cc/mm of 99.99999% pure hydrogen at pressures from 0 to 100 psig. The Balston H2-500 hydrogen generator uses deionized water and electricity. It produces hydrogen gas through electrolytic dissociation of water via the PEM. The resultant hydrogen stream then passes through a palladium membrane for purification. Because of the membrane''s gasaircompressorpressureswitch small pore size, only hydrogen and its isotopes penetrate it. A membrane thus keeps the hydrogen gas at a purity level of two orders of magnitude greater than desiccant or silica gel-based systems. new compressor technology introduced during the 2003 International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo), held last January in Chicago, may have a significant effect on the future of mid-range chillers and rooftop applications in water-cooled, evaporatively cooled, and air-cooled chilled-water and direct-expansion (DX) systems. Designed and optimized to take full advantage of magnetic-bearing technology, the compressor was awarded the first gasaircompressorpressureswitch AHR Expo Innovation Award in the energy category, as well as Canada''s Energy Efficiency Award for its potential to reduce gasaircompressorpressureswitch utility-generated greenhouse-gas emissions. The compressor is key to a new water-cooled centrifugal-chiller design, with Air-Conditioning and Refrigeration Institute (ARI) tests indicating integrated part-load values (IPLVs) not normally seen with conventional chillers in this tonnage range.
