Dan,
I did a quick look
on the web for Thermal shock chambers and found a Thomas registry listing a lot
of companies providing thermal shock chambers.
I did the electrical
design and wrote software for a Thermal shock chamber a few
years back. The equipment pneumatically cycled parts from a gas furnace
(2000F) chamber to a nitrogen cooled air chamber but, this was mostly built in
house by a mechanical engineer I used to work with. The cooled air
temp you are looking for might be hard to get, at -40C, because of the
transition from chamber to chamber because of the large temperature gradients.
If you have any questions about it let me know.
