Abstract

A thermal capacitor includes a shell and a PCM. The shell includes a first major surface that is configured to contact a container including media to be frozen. The shell defines a cavity in which the PCM is disposed. The PCM has a transition temperature in a range of −80 degrees Celsius to −50 degrees Celsius and is configured to rapidly freeze media from room temperature to −60 degrees Celsius with the container including the media in contact with the shell in an enclosed space.
