Hello, Since the last patch, we have a new freezing level, the "Deep Freeze" that comes with -18°C and under temperature. But I feel the system is not logical, see those examples. First, to have a perfect food conservation you have to associate : -18°C + sterile atmophere. Example 1 : powered fridge + sterile atmosphere = -3% / cycle   Example 2 : fridge + sterile atmosphere + -18°C = 0% / cycle (You can unpowered your fridge)   Example 3 : unplug
