-80c Equipment

Anyone running jacketed setups for processing at -80c?

Curious if you have any data on internal vessel temps while empty and running coolant. Can it hold a -80c vessel temp while empty?

Chillers are readily available as are jacketed vessels, but most of the thermodynamic effects making the process work rely on process fluid inside the vessel to transfer heat (liquid is a better conductor than air).

Yes. With intact seals and external insulation.
