Cold storage unit
From Memory Alpha, the free Star Trek reference
(Redirected from Cold-storage unit)
Cold storage units are, in simplistic terms, industrial refrigerators. Generally they are used to maintain large mechanical parts, weapons and matter that are unstable.
They are commonly used by the Breen, but were also used by the Maquis to maintain biogenic weapons. The weapons were 'bulky and very unstable' and required a cold storage unit to maintain them until they were to be used. (DS9: "For the Uniform")
