-60°C...
Nh3 nitrogen cooling systems.
but you must accept to waste nitrogen, or if you can recover on other plant.
In pharma industry its usual.

hi, i am also supposed to design a blast freezer with -60C room temperature. won't ammonia or co2 be enough for this temperature level? also, there is a combination of other rooms at different temperatures (-30C cold store, then other high temperature rooms). any advise on a good system for this would be very much appreciated. thanks!

Check out the Air system it was designed for Tuna since it is a requirement of -65C in Japan for Tuna.
If you let me know were you are located I can get you a contact number for your closest Mayekawa rep
