What is the difference between a walk-in cold room and a walk-in freezer room?
In short, one is much colder than the other.
Walk-in Cold Rooms
Walk-in cold rooms will operate in one of two temperature zones. The first option is when they operate between 2 -12 degrees. In industry terms, this is often referred to as walk-in chiller rooms as they are used to store consumable goods that are rotated every few days.
The second temperature zone operates between -2 and 5 degrees. This is generally used for products that are used in a few days to a few weeks. Storing at a colder temperature is better to preserve items that quickly go out of date. Keeping just below freezing is the optimum temperature for a lot of food products to ensure they stay fresh for as long as possible. You can get walk-in cold rooms to operate in both zones.
Walk-in Freezers
Walk-in freezers look identical to walk-in cold rooms; however, they have a much lower temperature. Walk-in freezer rooms usually have a temperature range of -18 degrees to -22 degrees. These temperatures are classed as ‘deep freezing’ and can keep products preserved for months or even years in some cases, to boost stock longevity.
