Designed for high purity and noncorrosive applications, Model 8404L protects system purity by allowing line purging and cleaning during dewar changeouts. Made with a powder-coated steel chassis, the liquid ChangeOver regulator system is designed for use with dewars having safety-relief valves settings of 230, 350 or 500 psig. Its gas-saver circuit directs the reserve dewar's accumulated head gas pressure to the primary source, where it can be used instead of being discharged to the atmosphere.
