Quantum Cryo Inducer

A Quantum Cryo Inducer is a Decepticon invention. It was never stated what the device actually does, but presumably it cools things down.

"Persuasion"
Only three Quantum Cryo Inducers were ever constructed. The prototype was kept on board the Nemesis in a store room. Ratchet noticed it when Megatron was showing him around the ship, and was impressed at its existence.
