The 530 Series Switchover System provides a continuous supply of non-corrosive, non-oxidizing gas in applications requiring 400 PSIG (27.6 BAR) or more. The system includes options for multiple inlet configurations permitting use with up to two cylinders per side. The CONCOA 530 Series pressure differential switchover is constructed from chrome-plated brass and is ideal for use with nitrogen, helium, argon, or hydrogen, where cylinder fill pressures can be as high as 6000 PSIG (415 BAR). Optional Altos 2 remote alarm capability provides audible and visible warnings of cylinder depletion.
