Pump Control Center

The Pump Control Center is a custom computer network that requires only a Cat 9 cable to communicate with the entire pump station network.


Four major functions include:

  1. Controls the on/off function for each pump including the cool down process. Saves time and labor, and gives your pump equipment a longer life span
  2. Acts as a "traffic controller" for the fill station. The system controls the queue process for the pumps by identifying the station and the gas that should be pumped. As the fillers call for a gas, the Pump Control puts the request in queue. As soon as the pump is available, the Pump Control releases the authority to the next user.
  3. Monitors the pumps by temperature and pressure, automatically adjusting the fill process as needed at the pump. As the fill cycle reaches target fill pressure, the Pump Controls slows down the speed of the cryogenic pump in order to better control the limitation of gas flow. 
  4. Collects and stores a wide range of pump performance data, logging data from every fill.
