The Chemisens Batch Injector is designed for batch dosing of solid and extremely viscous materials. The injector is charged, closed, and then installed inside the Chemisens reactor. It can be opened remotely and all the enclosed material is then delivered to the reacting system inside the reactor. Both the injector chamber and the enclosed material will reach the same temperature as the liquid surrounding the chamber inside the reactor. No thermal effects related to temperature differences will occur when the chamber delivers its material to the reacting system. The atmosphere inside the chamber might be inert gas thus avoiding contact with oxygen or moisture. Designed to work up to 20 bar pressure, available in SS3116 and HC276 with special stirring blade included.
