Ball Aerospace Next Generation 2-Stage 35 K SB235 Coolersck Sensor. A qualification unit SB235 was developed and has accumulated 2500 hours in a life test at the Air Force Research Laboratory (AFRL). The SB235 and its higher capacity derivative SB235E were designed for high cooling capacity, power and mass efficiency, and producibility for multiple unit build applications.
