Electronic switchover system for hazardous gas applications
588 switchover system shown

The 588 Series Switchover is a fully automatic system that provides a continuous supply from either the liquid or vapor phase. Designed to be the industry’s safest fully automatic switchover method, the 588 switchover utilizes either scale or transducer inputs to achieve up to 99% cylinder utilization of flammable, toxic, or corrosive gases. Employing the technologies of the CONCOA emergency shut-off controller combined with the Altos 2™ system monitor, the 588 Series automatic switchover system enables the user to match the appropriate degree of safety to the classification of gas. The CONCOA 588 Series switchover system includes a pneumatic emergency shut-off controller, Altos 2 electronic system monitor, cylinder scales, and rubber cylinder ramps (scale systems only). A variety of optional system components are available based on application requirements.

  • Micro-processor control permits fully automatic priority assignment for uninterrupted supply
  • Metal-to-metal seals prevent the possibility of gas contamination
  • Emergency shut-off (ESO) controller ensures extremely high safety performance
  • 4-20mA transducer, scale, or user signals provide flexibility for specific applications
  • Field programmable and configurable system supports expansion from pilot to production facilities
  • Altos 2 electronic switchover monitor facilitates continuous system operation

  • Temperature range: -40°F to 140°F (-40°C to 60°C)
  • Material: 316L Stainless Steel
  • Connections: 1/4 in FNPT or 1/2 in FNPT
