Dry Ice , Gas  and Equipment / Storage

Transport of perishable cargo

Weight for weight, dry ice has approximately 5 times the calorific cooling capacity of wet ice. This means that to achieve the same cooling effect as that of 1 kg of dry ice you would need 5 kg of wet ice. This is especially beneficial if you are transporting your product, as transport costs (especially airfreight) are affected by the overall weight being transported (less total weight using dry ice as a refrigerant = lower transportation costs).

As the dry ice sublimates (melts), no liquid residue is left in your storage container (as would be the case with melted wet ice). This has a benefit as there is no water lying in the bottom of the container which could spread bacteria and contaminate the perishable product.

Because dry ice is made from CO2 - as it sublimates - it constantly releases a blanket of CO2 gas around the product. This protective blanket of CO2 gas has a naturally bacteriostatic effect, due to the fact that the CO2 gas replaces the oxygen in the storage container. This can have a significant effect in slowing down, and inhibiting, the growth and proliferation of various aerobic microbes which can lead to the spoiling of perishable product.

Dry ice can be used in either pellet or block form to transport almost any perishable product. The quantity and type of dry ice required will depend on the nature of the product, transport time, ambient temperature and the required product temperature which needs to be maintained. We can assist with these calculations and offer free advice and support in this regard.
