Before we dig into cool chain transport containers, let’s began with the definition derived from World-Health-Organization (WHO) publication. The model requirement of a cool room shipping container is currently one of the most sensitive essentials, especially when transporting pharmaceutical products.

Active System

An active powered system uses electricity and a particular fuel to upkeep the temperature-controlled surroundings inside the insulated and enclosed thermostat regulation like refrigerators, cold rooms, air containers, temperature-controlled trucks, and refrigerated ocean.

Passive systems

The passive system is temperature control technologies that maintain the temperature-controlled surrounding inside the insulated enclosure. A passive system can operate with or without thermostatic control. It also works with a finite amount of the pre-conditioned coolant that runs in frozen or chilled gel packs, dry ice, phase change materials, and much more.

Internal temperature regulation

Both definitions refer to thermostatic control, which is active temperature regulation. The thermostat offers intelligence inside the container that decides active cooling significantly when the insulated enclosure temperature rises. Also, it deactivates the cooling system when the temperature inside drops.

With this latest technology, the passive cold shipping container decides when to start and stop cooling while regulating the internal temperature actively. Therefore, it removes the need for packing protocols used to develop passive packages that don’t have active temperature regulation.

How passive cold regulator works

The passive cold chain transporting container with an active thermal regulation uses the thermostats to detect the container’s internal temperature. If the container’s internal temperature rises approximately above 5°C, then the thermostat will connect the conduction path that enables heat inside the container to flow.

If you want to prevent a container’s heat flow from a payload area to freeze the PCM except a thermostat allows it, you will have to separate the PCM from a payload spot. Therefore, this can only be accomplished by the vacuum panel’s insulation that separates the PCM from a payload area. The conduction and thermostat path are usually installed via the insulation’s penetration that allows the heat to flow through a conduction path into the PCM.

Advantage of the passive cooling chain over a passive chain shipping container

You can appreciate the passive cold shipping container with an active control; it offers a distinct benefit over a full passive container. A dynamic thermal regulation compensates for the unexpected ambient temperature event during a transit. It eliminates the need for packing protocol need for passive packages that don’t have active temperature regulation.

Conclusion

Cool room shipping containers are pallet sized bulky and large shipment. Additionally, they also come with an extra volume of small package shipment where passive system and active thermal regular mainly used.
