Nitrogen Supply

CryoFill Station Specifications
Automatic filling station for liquid nitrogen containers

Application
The CryoFill station is used, if many containers are to be filled by different users with liquid nitrogen and the filling amounts must be allocated for cost calculation. The system is process-and safety-optimized. The user has to be instructed and has to wear face and hand protection during the filling-process.

Structure

Description
The user passes through the access control system in the filling area and identifies himself via touch screen on the control cabinet. His identification data will be displayed and the system is activated. In the next step, the user places the container in the on the scale. The nitrogen container will be identified and the data is forwarded to the cabinet where all container data is stored and the capacity will be calculated. Then, the user lowers the filling lance into the container. After activating the filling process is performed automatically. The emerging fog during filling will be removed through the ventilation system. Touchscreen as well as light signs indicate, when filling process has been completed.
Additionally, accustic operating instructions are issued by the speech module. The user lifts the filling lance back to its initial position and removes the filled container. The filled amount of nitrogen is assigned to the user as well as the container to be processed by cost center management. It can be retrieved and processed electronically. If no other container has to be filled, the filling area has to be left within a defined time span and the door has to be closed.
CryoFill station includes a fully programmable control for every conceivable application. The system can be extended with the functions and control devices individually needed for a nitrogen filling station.
