Cooldown box, cooling box, or cooling chamber is a machine that is used to cool cryonics patients to liquid nitrogen temperature (77 K, −196 °C, −320 °F) before they are placed in a cryocapsule for long-term care. The cooling is done after perfusion (except in straight freeze cases), and the cooling takes a few days.

There are computer-controlled and human-controlled cooldown boxes. Since 2005, the Cryonics Institute has had two computer-controlled cooldown boxes, a large one for human patients and a small one for pets and testing.[1] Also the Alcor Life Extension Foundation, the European Biostasis Foundation, KrioRus, the Shandong Yinfeng Life Science Research Institute, and Southern Cryonics have cooldown boxes.
