SGD Inc., (www.sgd.com) a single source specialty gas equipment supplier, has introduced a new changeover manifold, that the company said is the most advanced high-purity, fully automatic changeover manifold available.

The Auto-Logic II is designed to allow users to switch from high pressure cylinders on both sides to low-pressure cryogenic containers on one side and high pressure cylinders on the other side, or cryogenic containers on both sides with just a few screen touches. In that way it is like its forerunner, the company's Auto-Logic manifold.

The company said the capabilities of the Auto-Logic II provide customers with the best changeover system to suit their operations. The unit provides the user with simple, intuitive operation via a color touch screen - no buttons to push and no knobs to turn, said SGD.

Other features include constant visual monitoring of gas supplies on both sides; “Leak-Check” monitoring alerts the user to low reserve side gas pressure of either high-pressure cylinders or cryogenic containers while in standby; delivery pressure monitoring with both a high and low alarm setting; audible and visual local alarms at changeovers, delivery pressure anomalies, and “Leak-Check” alerts, and other features.

SGD Inc. offers a complete line of regulators, flow meters, purifiers, manifolds, gas detectors, and accessories for those who use gases.
