Temperature mapping is the process of recording and mapping temperature in three-dimensional space. You might think that in a small fridge, large cold room, freezer or warehouse the temperature would be the same everywhere, but you may be surprised to learn that the temperature can vary by up to 10°C from one place to another.

Temperatures in the corners will most likely be different than the center of the space being measured. We all know that cold air sinks and warm air rises, so it goes without saying that the temperature at the bottom of a cold room will probably be different than the temperature at the top of the cold room.

There are also “specific areas” inside the walk-in freezer where the temperature will also differ, such as: next to the cooling fans where the temperature will be lower, or near the doors where it will likely be warmer.

Why is the temperature map of your cold storage area important?

The effectiveness of the product is related to the correct storage of the goods. Fruits and vegetables that have been stored in an area that is too cold can freeze and spoil; Vaccines stored in a refrigerator can get too hot or too cold and reduce/destroy the effectiveness of the drugs. Ensuring that all locations within the refrigerated area are within the correct temperature range is critical to maintaining product quality.

Temperature mapping and temperature monitoring are integral to the storage of goods such as food and medicine.

How to perform a temperature mapping?

Data loggers must be strategically placed within three-dimensional space to map temperatures along a horizontal, vertical, and depth plane, as well as in locations that are likely to have temperature variations.

Temperature monitoring should be done within a normal business day rather than a weekend, as the internal temperature of the space will vary depending on how many times the cold room or warehouse doors are opened and closed. Ideally, you should use a company with experience in temperature mapping to ensure your temperature controlled storage area is mapped correctly, followed by placing data loggers and sensors in the correct locations (warmer and colder) for a continuous monitoring.

CoolPac specializes in temperature mapping and helps companies install a quality data recording system that meets the requirements of authorities such as HACCP or TGA.
