Before debating about the function of the passive and active temperature container, it’s vital first to understand what “WHO” all is about. “WHO” stands for World-Health-Organization publication. The model for a passive and cool room shipping container is now the most crucial, particularly in shipping pharmaceutical products.

Active System

The active system usually uses electricity particularly maintain the temperature-controlled environment inside enclosed and insulated thermostat regulation such as cold rooms, refrigerators, air containers, refrigerated ocean and temperature-controlled trucks.

Passive systems

The passive system refers to a temperature control technology that maintains the temperature of the environment inside and insulated enclosure. A passive system has been designed to work without a thermostatic device. It can also operate with a limited amount of a pre-conditioned coolant that runs in a frozen, dry ice, chilled gel packs, phase materials change and many more.

Inside temperature control

Inside temperature control refers to a thermostatic control with active temperature control. A thermostat provides intelligence in a container that controls a dynamic cooling system when the inside temperature drops.

 With inside temperature control technology, a passive control container controls when the cooling system stop or start when controlling inside temperature actively. It, therefore, removes packing protocols need that usually uses to create passive packages that don’t contain an active temperature control.

How passive system regular works

The passive system container is for transporting product under active thermal control. The passive system has been installed a thermostat detector to maintain the temperature within the container. If the temperature inside the container rises with approximately 5°C, the thermostat will connect to the conduction path to allow inside temperature to flow.

If you don’t want the heat inside the container to flow from the payload to freeze a shipment, you can try to isolate the PCM the payload spot. Thus, it can be accomplished only by a vacuum installation panel that isolates a PCM from the payload spot. The thermostat and conduction path is installed through an insulations penetration allowing the flow of heat through the conduction path to the PCM.

Advantage of a passive cooling over a passive system shipping container

Passive cold container for shipping is useful since it has been designed with an active control system to provide a distinct advantage over a passive container. A dynamic thermal regulator compensates favorable temperature ambient during transit. It, therefore, removes the packing protocol hassle and need for the passive packages that don’t have an active temperature regular.


The cool room shipping container is a pallet-sized large and bulky shipment that also comes with more volume of small package shipment. Therefore, this is where an active thermal and passive system primarily used.
