2100-Series Low-Flow Hydrogen Purifier |
Introduction:
Power+Energy's 2100-Series hydrogen purifier provides a cost-effective, easy-to-use, and compact solution for ultra-pure hydrogen production. Our hydrogen purifiers have been designed to produce a continuous supply of low-cost ultra-pure hydrogen from commercial cylinders or an in-house source of hydrogen. Efficiency is a top goal: The 2100 Series provides nine-nines purity (only 1 ppb total impurities) at flow rates of up to 30 standard liters per minute (SLPM).
Reliability:
The Power+Energy 2100 Series offers such unique features as a compact design and a PC board that constantly monitors the purifier's status, comparing temperatures, rate of rise, and other details to ensure that it operates safely and within precise guidelines. Each unit is helium-leak-tested three times during assembly, and is then bench-tested before shipping to ensure maximum reliability.
Principle of Operation:
A Power+Energy hydrogen purifier consists of a 316L SS cell, incorporating a large-diameter palladium-alloy tube that acts as the diffusion element. Hydrogen gas is brought into contact with the inner surfaces of the palladium-alloy tube, which acts as a selective barrier, passing only atomic hydrogen through the tube wall while excluding all other gases. Molecular hydrogen is adsorbed onto the surface, where it dissociates to become atomic hydrogen. The process continues as the atomic hydrogen gas diffuses through the palladium-alloy lattice as determined by the pressure gradient. The hydrogen atoms then recombine on the low-pressure side of the separation membrane, and are desorbed as hydrogen molecules.
Power+Energy's use of an inside-out architecture for capturing ultra-pure hydrogen is superior to the small-diameter tubing used in competitive models that employ conventional outside-in methods. Power+Energy's inside-out method produces cleaner hydrogen for longer and with far less maintenance, as the outside surface of the large-diameter tubing can easily be thoroughly cleaned.
Applications:
Power+Energy's hydrogen purifiers are ideal for use in small MOCVD reactors, laboratories, universities, and anywhere else ultra-pure hydrogen is needed.
