With cold chain logistics, the key is maintaining temperatures at freezing or ambient temperatures and constantly evolving to find the right solutions for it.  


For vaccine transportation, dry ice is popularly used because of its ability to provide freezing temperatures such as -60 degrees Celsius which is needed to maintain the shape, form and quality of the vaccine. 


However, Dry ice comes with a number of disadvantages.


What is dry ice? 

In its solid form it is carbon dioxide which if stored carefully is not harmful. However, dry ice is available at extremely cold temperatures and can be dangerous if you come in direct contact with it. This is because with direct contact to skin, it can cause frostbite and burns, as it kills the cells of the skin. Secondly, it can build pressure or displace the levels of oxygen causing a risk of anoxia in closed spaces. This is especially dangerous when it comes to closed containers as the pressure levels can lead to an explosion, harming the person in contact with the container. In its liquid form, dry ice is essentially CO2. 


Dry ice is undetectable to the human eye, and on sublimation when the co2 replaces oxygen, can pose serious health risks to the handlers of the storage boxes. The unwanted CO2 levels can cause respiratory issues, heart related problems and sometimes even a loss of consciousness. 


With the above health risks, and dry ice being so essential, we need to look for a comprehensive solution. One which is safe to handle, and which provides the same freezing benefits as dry ice. 


At Tessol, our PCM solutions are accessible and reliable while also being able to provide temperatures of -60C and below. Our PCMs are charged for 5 hours or more, and maintain temperatures up to 8-10 hours. 


Vaccines being temperature sensitive, need to be delivered at the right temperature. In case the engine fails, or the consignment delivery is delayed due to traffic conditions, the PCM technology being engine and fuel independent will not fail. More so, it maintains temperatures at Indian ambient conditions and ensures that the vaccine will be delivered successfully for point to point transportation.


The benefits don’t just end here. A PCM based solution is highly flexible and can work with all melting points. In its liquid phase, it helps prevent hypothermia and in its solid phase it can prevent or delay overheating. 


At Tessol, our PCM solutions are available throughout the supply chain or can be used solely for last mile deliveries. For our secondary and tertiary trucks, our PCMs are charged through the help of compressors, which are placed on top of the truck. These compressors electrically charge the PCM to the desired temperature before the consignee is placed. 


For our storage boxes, the PCMs are placed inside the box and are temperature controlled. The storage boxes work ideally for last mile deliveries and ensure no harm to the consignment. You will save on costs, while also being able to successfully deliver the need of the hour- the vaccine.
