Mapping Nordtec

Mapping in warehouses and premises

Temperature mapping, temperature mapping or just “mapping”… as we all know, there are many names for it. Whatever it is called, it is about ensuring that temperature levels in spaces remain within certain limits.

In businesses with warehouses and logistics centers, as well as in pharmaceutical production, it is standard practice to carry out and document temperature mapping. This is done to ensure that different raw materials, substances and products are stored in optimal indoor climates and do not risk deterioration due to incorrect temperature levels.

Important to map large temperature differences

Mapping should be done in both summer and winter, to get a clear picture of how large differences in outdoor and indoor temperatures affect carefully specified climates in key locations. A mapping shows where it is particularly important to measure the temperature in a space and that you might want to avoid storing sensitive products there.

How does mapping work? Well, broadly speaking.

Preliminary study and preparation

– In order to make a reliable mapping, we always start by carefully studying all the drawings. We consider areas, volumes, shelf space design and other important parameters. Then we calculate where all the measuring points should be placed. Firstly, to ensure an evenly distributed measurement of the entire storage area. Firstly, to identify and monitor potential problem areas such as areas around windows and doors where temperatures can differ significantly from other parts of the space,” says Maria Almestål, lab manager at Nordtec.

A basic document is created and sent to the customer for approval of all measurement points. All documentation is in English so that everyone in international companies and authorities can understand the information.

Measurement and mapping

Before starting the measurement, a thermography is always carried out to locate any weak points in the spaces. The results are compiled in an appendix to the final report.

To access and measure high up on shelves and pallet racks, mapping staff sometimes need a ladder or skylift in some areas. It is up to the customer to ensure that these and other facilities are in place when the mapping takes place.

Unlike other market players, Nordtec follows the entire measurement process online and can detect the slightest risk of deviation. We also set up logs that help refrigeration engineers to set up cold rooms correctly before mapping, thus avoiding unnecessary deviations. And if desired, we can provide you as a customer with preliminary measurement curves, so that you are also updated during the mapping process.

Control and detailed report

– “The day after the measurement is completed, we dismantle all the loggers and perform an accredited calibration to ensure that all the measuring instruments have functioned smoothly throughout the mapping,” says Maria Almestål.

For one or two weeks after the mapping (the length of time depends on the extent of the mapping), the results are analyzed and compiled in a report in English. It shows the temperature variations at all measurement points and a summary of the hottest and coldest location in each space.
