537 Series AutoSwitch GL

Liquid primary, high-pressure reserve switchover with stainless steel internals for ultra-high purity gas applications
5373004-01-001 shown

The 537 AutoSwitch GL is a continuous gas delivery system for ultra-high purity gas service that automatically changes cylinder or bank priority from cryogenic sources to a reserve bank of high pressure cylinders without transmitting pressure fluctuations to the use line. The CONCOA 537 AutoSwitch integrates seamlessly with the optional Altos 2™ remote alarm and includes a separate connector to construct an interface cable between the optional remote alarm and the AutoSwitch. For complete flexibility in source selection, including low-loss technology, consider the CONCOA IntelliSwitch Series gas management system.
