Freeze water into ice. Enclose items in ice to slow spoiling. Store spoilables in a refrigerator to stop spoiling completely. Fridges draw power based on ambient temperature. Also adds cooled wagons.
You can't place the Freezer anywhere except Aquilo because the Temperature requirement is now below 50 K, which is closest to absolute zero than to 0 Celsius ahah.
My mod uses Celsius, because I believe it to be most readable/intuitive.
If other mods use Kelvin and override the temperature, then they are incompatible.
In case of conflict, you can disable temperature logic in mod settings.
