 HYDROGEN GENERATORSGenerators can also make hydrogen using one of 8 hp gas air compressor 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 hp 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 gas for purification. because of the membrane''s 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 air gel-based compressor 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 8 hp gas air compressor cooled, and air-cooled chilled-water and direct-expansion (dx) systems. designed and optimized to take full advantage of magnetic-bearing hp and gas technology, the compressor was awarded the first ahr expo innovation award in the energy category, as well as canada''s energy efficiency award for its potential to reduce utility-generated greenhouse-gas emissions. the compressor is key to a new water-cooled centrifugal-chiller design, air with air-conditioning and refrigeration institute (ari) tests indicating integrated part-load values (iplvs) not compressor normally seen with conventional chillers in this 8 tonnage range. efficiency is further enhanced with the use of magnetic bearings, which avoid fire friction of rubbing parts associated with traditional oiled bearings. conventional bearings can use as much as 10,000 w, while magnetic bearings require only 180 w. that amounts to 500 times less friction loss. current development projects are hp expanding gas the range and duty of the compressor wheels and promise to offer even greater efficiency for water-cooled and air-cooled duties and different capacities.controlsthe new compressor effectively is a computer. it provides diagnostic and performance information through modbus to the refrigeration system, air which compressor then communicates to the building automation system through modbus, 8 lonworks, or hp bacnet.chiller applicationthe gas compressor manufacturer and a major chiller manufacturer teamed up to develop a line of ari-certified water-cooled chillers, which were expected to air be introduced in january 2004. the compressor combination 8 of flooded-evaporator hp technology and an oil-free system has allowed very close approaches and, subsequently, enhanced performance. gas the integrated vfd allows excellent part-load performance as power consumption drops off, air depending on the head relief, near the compressor cube root of the shaft speed.
