538 Series IntelliSwitch II

Web-enabled, high flow electronic switchover for cryogenic and high purity laboratory applications
538C00G-01-001 shown

The 538 Series IntelliSwitch™ II electronic gas switchover is a revolutionary, web-enabled gas management system engineered specifically for either cryogenic liquid cylinders, high pressure gas cylinders, or any combination of both. Driven by microprocessor control and integrated software logic, the IntelliSwitch features an electronic economizer that eliminates liquid cylinder vent loss and proprietary low-loss technology that reduces costly residual return. With on-site or remote source selection activated by a simple push-button or web-enabled interface, this fully automatic changeover manifold ensures an uninterrupted gas supply. Its design delivers maximum process flexibility for high-purity, non-corrosive, and non-flammable gas delivery in critical laboratory analytics, pilot plants, and microbulk changeover supply applications. In addition, the 538 Series IntelliSwitch II is designed to interface with the CONCOA Altos 2 remote alarm.
