What is dry ice and how quickly does it evaporate?
Dry ice is the solid form of CO₂ and is widely used for cooling medical samples, food, sealed shipments, cleaning, and special effects in the hospitality industry. Because dry ice converts directly from a solid to a gas (sublimates), it evaporates continuously. The rate at which this occurs depends on factors such as the quantity, storage method, and ambient temperature.
Evaporation rate per amount of dry ice
The detailed data are averages when stored in an EPS box from Droogijs-Shop.nl :
- 5 kilos of dry ice : completely evaporates in approximately 24 to 36 hours
- 10 kilos of dry ice : evaporates in approximately 36 to 42 hours
- 15 kilos of dry ice : shelf life of approximately 42 to 52 hours
- 25 kilos of dry ice : remains usable for 3 to 4 days
Please note: this may happen faster at higher temperatures or with heavy packaging.
What is the best way to store dry ice?
For optimal storage of cooling capacity, it's important to store dry ice in a good EPS container (such as the standard one supplied by droogijs-shop.nl ). These containers are specially designed to evaporate and move without pressure buildup, unlike airtight packaging.
Additional storage tips:
- Store in a cool, dry place (preferably below 20°C)
- Open the EPS box as little as possible
- Avoid storage in fully closed spaces (safety reasons) so keep it in a ventilated area
- Order gloves and a shovel for safety.
Conclusion
The evaporation rate of dry ice varies significantly depending on weight and storage method. With EPS boxes from droogijs-shop.nl, it stays fresh longer . Order easily online and choose from various quantities, tailored to your shipment.
