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 Autoswitch is equipped with LED status lights to indicate the condition of the gas cylinders. The CONCOA 537 Autoswitch can also be used in conjunction with the 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 gas management system.
