Air is like water – it follows the path of least resistance

Unless air is forced through the product or into all parts of the chilled space – known as a cube, it will follow the path of least resistance. Therefore, although the thermometer indicates the correct temperature at a particular point, it is very unlikely that all parts of the cold cube will be at the same temperature. Up to a million data points enable us to measure efficiency.


A thermal map is a three-dimensional (3D) colour illustration of temperatures, monitored within a cold cube every few minutes over a period of approximately six weeks. The data comprises of millions of temperature recordings that are scientifically analysed and mapped diagrammatically onto a floor plan of the chilled space or cube. The results indicate where on the grid and at which height the temperatures are, and whether they are at the desired set point. The thermal map is a tool that we use to pinpoint the likely causes of problems for further investigation or remedial action.

Coldcubed® has been responsible for the successful thermal mapping of numerous cubes with valuable results. These results helped to focus investment for remedial action. Subsequently, the tool has been used as a diagnostic procedure to measure the improved performance of cold cubes.

Thermal mapping is a diagnostic tool that enables a 3D assessment of a temperature-controlled cube to evaluate its performance. This efficacy assessment assists in calculating the food risk and investment risk prior to purchase, installation or the formulation of contractual obligations.


Legal Requirements


Entering into the temperature-controlled supply chain involves a chain of custody between trucks, sheds and other responsible parties. Therefore, the business case is to ensure a trusted temperature environment. This would require a thermal map of all the cold spaces or cubes in the chain and in transit on trucks – thermal maps provide the diagnostic tool to assess their efficacy.

When entering into contractual agreements with customers, the performance of those facilities is an unknown and would require an assessment / thermal map.

Thermal and humidity mapping is a diagnostic tool that enables a three-dimensional assessment of a temperature-controlled cube to evaluate its performance. This assessment helps to calculate the risk to:

  • the food products in storage;
  • the investment prior to purchase, installation or the formulation of contractual obligations.

Creating thermal maps of the supply chain is a diagnostic tool to provide insight into shortcomings in infrastructure, the capacity of refrigeration, the integrity of the insulation (e.g. door seals, doors opening and closing) and the impact of inbound and outbound processes.

Temperature Monitoring Live Dashboard


Coldcubed® supplies dynamic reporting of the temperatures in the supply chain – from the distribution centre (DC) to the truck and during handovers between the supplier and the DC; the DC and the transport, as well as at the back door of the retail / hospitality / wholesale outlets.

A dynamic or real-time reporting interface is customised according to the client’s needs. Through our experience and understanding of the demands of cold chain requirements, Coldcubed® is able to tailor the mass of data and provide essential dynamic reports according to specific customer requirements. These reports are provided in formats to suit clients’ needs – as often as parameters specify.
