CONCOA IntelliSwitch II


IntelliSwitch II

The fully-automatic IntelliSwitch II™ gas switchover is CONCOA’s revolutionary new generation of gas management systems. The IntelliSwitch II™ features an onboard web server and proprietary embedded software, allowing remote monitoring, secure system configuration, and e-mail notification of real-time system status and events. It is ideally suited to interchangeable service/continuous supply in analytical laboratory, chemical process, instrumentation, and critical gas supply applications. The IntelliSwitch II™ offers continuous pressure and flow control from liquid or high pressure cylinder sources. The end-user selects the ideal mode of supply by the simple push of a button. Proprietary software logic lowers yearly gas costs by eliminating liquid cylinder vent loss and excess residual return. It is these features which make the IntelliSwitch II™ the perfect gas management system.   
The user can select from any model of delivery liquid cylinders to high pressure cylinders. The end user selects the ideal mode of supply by the simple push of a button. Where pressure is controlled by other devices or where pressure control is not required, the 544 provides a reliable and continuous gas supply.
