Concoa (www.concoa.com) has developed a new generator back-up panel from that is designed to provide an uninterrupted, reserve supply of gas to nitrogen, air or hydrogen generators in production. The Series 540 back-up panel automatically activates to supply gas in a power loss. The reserve shuts down when the generator resumes operation. Users set the pressure at which reserve supplies are activated. Check valves on the generator and on the reserve prevent back flow to the generator or reserve cylinder, and shut-off valves on the generator and reserve cylinder allow each to be isolated or disconnected. A remote alarm package is available.
