Caja portadora de vacunas

The temperature during the process of vaccine delivery, loading, transportation, and storage must be strictly controlled, and the entire process needs to be maintained at 2-8 ℃ or -15-25 ℃ for dark and cold chain transportation and storage. It is required that even when there is a large temperature difference between the inside and outside of the box, the heat exchange rate can be slowed down, thereby playing a long-term role in maintaining heat or cold. No power supply is required, and the entire low-temperature storage process uses phase change refrigerant refrigeration, which can maintain the temperature inside the box without using electricity. It is energy-saving and environmentally friendly, and can be reused, suitable for long-distance low-temperature transportation of drugs, biological reagents, blood and other products without electric refrigeration.
