583 Series AutoSwitch 2

Electronic gas delivery system with stainless steel internals for high purity gas service
5832011-01-001

The stainless steel 583 Series AutoSwitch 2 is an electronic gas delivery system for high purity gas service. Typically used for critical purity applications in the laboratory or process plant, the 583 AutoSwitch 2 automatically changes cylinder or bank priority from the primary source to a reserve supply without transmitting pressure fluctuations to the use line. The system comes with inlet pressure transducers to help monitor gas supply pressure. Designed without solenoids in the gas stream, the AutoSwitch 2 provides fully automatic priority assignment with 1 x 10⁻⁸ scc/sec helium leak integrity. The 583 AutoSwitch 2 is intended for high-pressure supply sources only. For cryogenic liquid supply systems, CONCOA recommends the IntelliSwitch family of products.
