The outbreak of the COVID-19 pandemic has caused tremendous economic and life property losses worldwide. The control of the COVID-19 pandemic globally can only rely on the development and widespread use of vaccines.

Currently, the temperature requirements for COVID-19 vaccines developed by global pharmaceutical companies are generally -20℃ to -80℃, which is much lower than the standard temperature of 2℃ to 8℃ for most medicines during transportation. According to the Associated Press, the entire process from the production of these COVID-19 vaccines in factories to being pushed into syringes must be carried out continuously in a sterile environment within this temperature range. How to achieve global transportation of COVID-19 vaccines in the near future has also become a major challenge. Once a vaccine is developed, the cold chain transportation of COVID-19 vaccines should be at the pinnacle of the cold chain industry pyramid to facilitate rapid vaccination globally.

Regarding the public's concern about the cold chain transportation of COVID-19 vaccines, Hema New Energy (HM) has successfully developed various mature and efficient phase change refrigerants, especially the ultra-low temperature phase change refrigerants at -70℃ to -80℃.

The three main temperature ranges for the cold chain transportation of COVID-19 vaccines and the refrigerants provided by Hema:

1. 2-8℃: HM-O5

2. -20℃: HM-E-24, HM-E-25

3. -70℃ to -80℃: HM-EO-57, HM-EO-75, HM-EO-80

Hema refrigerants will be on standby at all times to assist in delivering COVID-19 vaccines to various parts of the world, completing this 'century mission'!
