641 Series IntelliSwitch I

High flow electronic switchovers for industrial laser process gases
6415002-01-1010 shown

The 641 Series IntelliSwitch™ I provides continuous pressure and flow control from either liquid or high pressure cylinder sources, or any combination of both. The end-user selects the ideal mode of supply with the simple push of a button. CONCOA 641 Series IntelliSwitch features proprietary technology that ensures every customer maximizes the use of liquid cylinder gases by eliminating the primary cylinders' residual return loss and economizing the reserve cylinders' excess pressure. 641 Series IntelliSwitch I systems have the advantage of delivering higher pressure and flow capacity than other IntelliSwitch systems while offering the same proprietary IntelliSwitch technology. In addition, the 641 IntelliSwitch is designed to interface with CONCOA remote alarms.

Note: This item has been discontinued. Please see the CONCOA electronic 544 Series IntelliSwitch IIv for all applications previously using the 641 Series IntelliSwitch I.
