  • Patent number: 6378324
    Abstract: The thermally regulated storage container of the present invention comprises a cabinet housing with an one open face. A self-sealing and self aligning cover provides an environmental seal between an insulated storage area within the cabinet housing and an external environment. A modular environmental control unit is removably installed within the cabinet. This unit can control temperature, pressure, humidity or any other environmental condition. A ducting system within the cabinet mates with the environmental control unit. An environmental monitoring system monitors internal conditions of the storage container and provides an input to a control system operable to direct the modular environmental control. This ensures that the desired internal conditions are maintained.
