Pure nitrogen generator GCHA-21
Pure nitrogen generator GCHA-21 is intended for obtaining nitrogen of the highest purity in laboratory conditions, used to power analytical instruments (chromatographs, including those equipped with an electron capture detector, express analyzers of hydrogen content in metals, organic carbon concentration meters, sample evaporators, etc.). Due to the high output pressure, deep purification and low moisture content, the nitrogen produced by the generator can be used as a carrier gas. The resulting nitrogen can be used to create an inert atmosphere, fill low-pressure tanks, and other applications that require large, by laboratory standards, nitrogen consumption. The generator is powered by compressed air at a pressure of 6 ati from a compressor or air line. The contamination class of compressed air according to GOST 17433-80 should be no higher than 8. The generator meets the electrical safety requirements of class 1, type N according to GOST 12.2.025-76. Manba: https://www.nv-lab.ru/catalog_info.php?ID=6717
