Hello Ed,
I don't see a direct response to your question. In our experience
(unfortunately) most -80 can hold temp for 3-5 hours. Once you open the door
however the temp starts to drop fast. So, keep the door closed when you loose
power. You might also want to contact Minus 80, (855.646.8780) a freezer
monitoring vendor to discuss their experience. I think they have actual data
as you requested.
Good luck.

Hello Everyone,
Does anyone know how long a -80°C freezer would maintain temperature after
a power failure? Most helpful would be actual chart recorder data showing
temperature change vs. time.
Thanks!
