Our work uses LN2 as part of a high-vacuum pumping system to create the space environment for advanced spacecraft propulsion research. Sidney Lee delivered a unique portable LN2 solution on short notice to help us expand our pumping capacity for an international customer. The expertise of Sidney Lee personnel was crucial to the successful integration of the portable LN2 dewar into our existing infrastructure. Furthermore, the company pulled from a broad regional network to find a truck with the ability to maneuver in our physically-restricted facility to provide a continuous, remotely-monitored LN2 supply. We also found their personnel to be responsive to maintenance and hardware needs. Based our success with the initial solution and our positive experiences interacting with their employees, we contracted with Sidney Lee to install and supply a large, permanent LN2 dewar.
