We have discussed this topic some time back, and I relayed a suggestion
from the Danish Metrology Lab:   Use an unplugged fridge.

Apart from a good air volume and sensible insulation, if you rip out
the compressor, you can use the cooling circuit to do active temperature
control if you want.

Never attribute to malice what can adequately be explained by incompetence.
