Which size of pellets is best for my application?
16 mm for Industrial Cooling, Fog Machines, Food and Drinks Trade and Events and Entertainment etc.
3 mm as a Mix in Coolant, for Medical & Research Work, Education, Transport etc.
If you are not sure all small orders up to 30 kg can by special reqest be sent out as two separate bags of each size to enable tests to be made.
Please pick a quantity of dry ice pellets. For advice about your needs please contact our team
We can deliver on Weekdays or Saturdays, please select your specific delivery day on the checkout screen ( next working day is available up to 2pm on Fridays)
We may be able to accommodate same day delivery. Please contact our team on 0116 224 0072
Dry ice pellets come out of the production machine at -78.6 degrees C, so when they are fed into the insulated boxes we use for packing and despatch, the first thing to happen is that some of the ice will be used up to cool down the box. When the box is cold inside, but still at room temperature outside, heat will flow into the box and attempt to get the inside down to room temperature, so more ice will be used to absorb this heat. This process will continue until all the ice has been used up.
The time taken to use up all the dry ice by these processes will depend on:
– the insulating properties of the box material and its thickness
– the outside temperature
– the amount of ice in the box
To minimise losses we use a good quality thick walled Polybox which is chosen to balance cost against performance. We could use thicker walled boxes or ones made from better materials, but you would not like to pay for them.
Needless to say we cannot influence the outside temperature of the box during transit, and on occasions Couriers will leave vans in the sun in the summer and in sub zero conditions in winter.
The amount of ice in the box has an effect because small boxes have a higher ratio of box weight and surface area compared to the box contents. This means a greater percentage of a small amount of ice will be needed to cool the box than would be needed for a larger quantity of ice in a larger box, and there is relatively more surface area for heat transmission into the box.
All these factors explain why the shelf life of dry ice when kept in a closed insulated box varies considerably
Box sizes (external mm L x W X H)
7 and 10 kg 340 x 340 x 360
15 kg 450 x 450 x 380
20 to 30kg 500 x 560 x 420
Average Losses (standard UK weather, whatever that is!) assuming box remains closed, no ice is used and it is kept in a cool shady location. If the whole box can go in a freezer, these times will be extended.
Losses will be slightly lower for 16 mm pellets.
