Does Air Liquide offer a liquid manifold for liquefied gases like argon or carbon dioxide?
Our SCOTT™ liquid changeover system combines a pressure-reducing regulator with high-purity diaphragm valves to create a compact gas delivery system that provides continuous gas flow on installations where dewars are used. This system directs the flow of gas from two separate sources (dewars or banks) to your application. When one source empties, the changeover system automatically draws from the second source. The first source can then be changed without interruption to the outlet pressure. The Model 8404L is available in brass or stainless steel. It also features a built-in gas saver circuit that eliminates waste by preventing the reserve supply’s accumulated head gas pressure from being discharged to the atmosphere. During operation, the gas saver directs reserve supply pressure build-up to the primary supply where it is used. During shutdown periods, both supplies may be vented to the atmosphere. Adequate ventilation should be provided to safely remove or disperse the gaseous disch
