Deep-freezing box

The deep-freezing passive box is suitable for storing vaccines or other substances at a temperature of -78 ° C. 30 ampoules of vaccines are placed at the bottom of a hollow cylinder surrounded by dry ice. Thanks to the innovative design, the vaccines are still perfectly cooled, even if the supply of dry ice decreases significantly over time. The ampoule holder is equipped with an accumulation element for short-term maintenance of the vaccine temperature even when pulled out.
The box is well insulated with airgel and polystyrene with the addition of carbon nanoparticles to prevent infrared radiation. The refrigerant, 11 kg of CO2 in the form of dry ice, is placed separately from the sample and can be added continuously. The condition of the refrigerant stocks can be checked using a dipstick or electronically.
