Why make the switch from Dry Ice to PCM

Why make the switch from Dry Ice to PCM?

If you have a business which relies on cold chain logistics, you have probably come across the dilemma of using dry ice. Being the latest trend for vaccine transportation because of its ability to provide freezing temperatures such as -60 degrees celsius, most logistic companies would look into using it for last mile deliveries. However, Dry ice also comes with a number of disadvantages.

To begin, let’s break down dry ice. In its solid form it is carbon dioxide which if stored carefully is not harmful. However, dry ice is extremely cold and can be dangerous if you come in direct contact with it, leading to 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. 

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.


So, the real question is, would you still use dry ice and is it worth it? Is there a safer, cost effective alternative? With vaccines being so temperature sensitive, what is the next solution? 

With Tessol, we have got you covered. Our PCM technology is accessible and reliable owing to its sustainability, cost effectiveness, and temperature control. Our PCMs are charged for 5 hours or more, depending on the temperature required and can be temperature controlled to -25 degrees celsius and less, which works in the favour of the vaccine. 

Vaccines being temperature sensitive, cannot be tampered with. 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 is also compatible with 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 reefer trucks, our PCMs are charged and placed in compressors and help maintain the required temperature. 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 zero harm to the consignment. You will save on costs, while also being able to successfully deliver the need of the hour- the vaccine. 

Final Thoughts 

The Vaccine distribution is no joke, and we need to ensure that while delivering it successfully, we also minimise external side effects and harm to people in charge of the delivery process. Along with this, any consignment that is temperature sensitive, can pose serious health risks to the end user if not managed correctly at the right temperature. 

Make the change today, and choose wisely!
