These systems are available to temporarily protect the contents of the freezer against the
consequences of freezer failure or power failure. In an emergency, the system can inject either
liquid carbon dioxide or liquid nitrogen from a storage bottle. Carbon dioxide back-up systems will
maintain temperatures between -50 °C and -70 °C (subject to environmental conditions) for a
period of up to 48 hours, during which time the freezer can be repaired. Liquid nitrogen back-up
systems will maintain the freezer temperature down to -85 °C.
