1. A device for ultra low temperature (ULT) freezing, comprising:

  • a plurality of evaporators coupled to a payload bay with a multiplicity of coolant tubes in each evaporator, and further comprising one or more cryogenic valves coupled to the coolant tubes;

    a pump to force coolant flowing through the plurality of evaporators;

    a thermal box immediately outside the plurality of evaporators and payload bay to thermally seal the payload bay from the outside environment and reduce heat gain, the thermal box including high strength open cell panels and a vacuum or Vacuum Insulated Panels (VIPs) with polyurethane foam to fill the voids;

    sensors coupled to the plurality of evaporators to monitor vital parameters of the device;

    a processor;

    a wireless telemetry system to communicate one or more measured characteristics of the device in accordance with a service level agreement, to a remote computer; and

    at least one notification component that provides a notification associated with a specific customer, responsive to the one or more measured characteristics of a service, crossing a pre-defined threshold,wherein the one or more measured characteristics includes a temperature level and a humidity level, and the pre-defined threshold is a minimum liquid nitrogen level necessary for delivery of the service.
