Abstract

A freezer includes a plurality of evaporators coupled to a payload bay with a multiplicity of coolant tubes in each evaporator, wherein each tube enters and then exits the payload bay, further comprising one or more cryogenic valves coupled to the coolant tubes; a pump to force coolant flowing through the evaporators; sensors coupled to the evaporators of the freezer to monitor vital parameters of the freezer; a processor; a wireless telemetry system to communicate one or more measured characteristics of the freezer 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 measured characteristic of the service crossing a pre-defined threshold.

Claims

1-18. -18. (canceled)

19. A device, comprising:

cryogenic evaporators coupled to a payload bay with one or more cryogenic valves coupled to the coolant tubes;

a rubber pneumatic seal is placed between a freezer door and the payload bay;

a pneumatic latch for latching the freezer door, wherein the rubber pneumatic seal and the pneumatic latch are powered by pressure derived from an exhaust gas;

a pump to force a coolant flowing through the cryogenic evaporators;

sensors coupled to the cryogenic evaporators of the freezer to monitor parameters of the device; and

a processor that provides a notification if sensor output meets a predefined threshold.

20. The device of claim 19, wherein the processor maintains a setpoint for the payload bay, determined by the operator between approximately 20 degree C. and −

150 degree C., further comprising a measurement component coupled to the processor that measures a characteristic of service being provided to a specific customer in accordance with a service level agreement.

21. The device of claim 19, wherein the processor provides a temperature service.

22. The device of claim 19, wherein the processor predicts when maintenance is needed.

23. The device of claim 19, wherein the processor sends a message addressed to a customer to notify the customer about a measured characteristic crossing a pre-defined threshold.

24. The device of claim 19, wherein the processor sends a notification message to notify a service provider.

25. The device of claim 24 wherein at least one of a trouble ticket and a billing credit associated with the specific customer is generated in response to the notification message.

26. The device of claim 19, wherein the processor sends a message addressed to a monitoring entity.

27. The device of claim 19, wherein the characteristic measured includes temperature and humidity level, and the pre-defined threshold is a minimum level necessary for delivery of the temperature service.

28. The device of claim 19, wherein the processor maintains ultra low temperature (ULT) performance.

29. The device of claim 19, wherein measurements are captured by a plurality of sensors.

30. The device of claim 29, wherein at least one of the sensors is configured to communicate statistical information based on measurements of performance or energy consumption of the device.

31. The device of claim 29, wherein at least one of the sensors is configured to communicate analytical information based on a statistical analysis of measurements of performance of the device.
