New midsize models and features added in this PSA range

| By Mary Page Bailey

The NGP+ series of pressure-swing-adsorption (PSA) nitrogen generators (photo) is expanding with the introduction of two new models — the NGP 160+ and NGP 200+. The generators offer gas purity from 95% to 99.9995%, with flowrates up to 4,802 std. ft3/min. The midsize NGP+ models feature the Elektronikon Touch controller, which enables easy gas-purity selection and advanced connectivity options. This controller optimizes performance and continuously measures gas purity. It also monitors the feed air to safeguard the integrity of the adsorbent. Other newly available options include a room oxygen alarm and the ability to produce ultra-dry nitrogen. — Atlas Copco Compressors LLC, Rock Hill, S.C.
