Thermal Mapping Study

What is Temperature Mapping Study?

Temperature mapping study is a study to verify that the entire enclosed storage maintains a temperature within the permitted levels. A Temperature Study involves the collection of temperature around the length and breadth of a storage areas example like cold room, warehouse or chiller.  Normally the temperature recording will take a couple of days, then data are collected to check whether the temperature is within the set limits at all times.  Besides temperature, parameters like humidity could also be recorded, especially for a product that is sensitive to moisture.    

Why Temperature Mapping Study is needed?

The purpose of temperature mapping is to identify hot spots, to know how the internal temperature is affected by climatic changes or operation changes, in order  to better manage the storage conditions of your product. 

Once the hot spots are identified, corrective actions will be required to resolve these issues. If the corrective actions are not feasible, these area will have to be isolated and should not be used for storing of sensitive products.

Temperature mapping is compulsory for Pharmaceutical & Healthcare industries. However now-a-days, temperature mapping study is also widely required by Food Industries, Electric and Electronic Industries, Warehouse or Expensive Consumer goods, storage of important documents and also preservation of objects in the Museum and Laboratory and so on.

How to Perform Temperature Mapping Study?

Temperature mapping is performed by placing data loggers throughout a specified area for at least 3-7 days to study how temperature and humidity is distributed. The location and numbers of the loggers are mainly depending on the number and height of racks, the location of doors, ventilation in the warehouse, movement of the operator, location of the cold air supply and the de-humidifier unit, etc.

In general, one data logger should be used for every 5 cubic meters. While the duration of the study should be based on the frequency of product movement, equipment cycles (defrost cycles), operational schedules and potential ambient conditions.

The table below could use as a reference for determining the duration for performing temperature mapping in different areas/locations or specific equipment.

After Temperature Mapping Study is done, a report will be issued which includes the drawing of the location of the loggers, the date and time when the hot spot and cold spot occurred, the calibration certificate of the loggers and all the recorded raw data. Suggestions and rectifications also will be provided in the report. For example, if a hot spot is identified near the roller door entrance, a suggestion will be given to address and solve this challenge.

Temperature Mapping Study could be carried out in two ways. 

i.  You owned the data loggers and performed the test periodically by yourself 

ii.  Engage a third-party temperature mapping service provider to perform the study on your behalf. You will get an objective and independent report about the findings. 

Team Medical Scientific Sdn. Bhd. provides both options i. and ii. to our customers.
