Cold stores are extreme environments, but they're an absolutely essential part of the modern supply chain. Without these specialised warehouses, where temperatures can go as low as tens of degrees below zero, it would be impossible to store and distribute frozen goods. Even chill warehouses, which operate at much warmer (but still cold) temperatures are essential for the supply of perishable goods.
Cold stores are some of the most challenging environments that forklifts can operate in — temperatures as cold as -35°C are not unusual in these facilities, which are an absolutely vital part of the modern supply chain.
In these sub-zero conditions, steel can become more brittle, condensation can cause problems for a truck's mechanics, and operators must either wear insulating clothing or be protected inside heated cabins for their safety.
One of the biggest issues, however, is the cost involved with keeping the large area of the store colder than the North Pole. A lot of power can be needed to maintain the low temperature, and that's why it's important to maximise storage space as much as possible. This allows you to store more unit loads in a smaller space, and reduces the amount of energy needed to keep the store at these very low temperatures.
But what type of storage system allows for the densest storage?
