542 Series High Flow Back-Up

High flow electronic reserve system for high purity gas applications
5423004-01-0000 shown

The 542 Series High Flow Back-Up is designed to provide a smart reserve supply to high flow or bulk supply gas primary systems. If there is a loss of power, or if the primary supply system cannot provide sufficient gas, the 542 will automatically activate and supply gas without interruption. When the primary system resumes supplying gas to the application, the 542 Series back-up system will automatically turn off. The CONCOA 542 Series high flow back-up features an innovative onboard microprocessor and web server technology for remote monitoring and control functions. Together, this advanced system continually monitors pipeline pressure and reserves and can be programmed to engage at a specific pressure.

  • Programmable setpoint pressure permits the user to set the back-up to engage at a specific pressure
  • Programmable inlet alarm pressure allows user to set a low reserve alarm point
  • Onboard web server technology enables real-time, online system monitoring
  • High flow capacity supports building or facility systems
  • Check valve on primary and reserve prevents backflow to either
  • Max primary source pressure: 15 - 120 PSIG (1 - 8 BAR); 15 - 250 PSIG (1 - 17 BAR)
  • Temperature range: 0°F to 140°F (-18°C to 60°C)
