Pelletisers for Dry Ice Production
DRY ICE PELLETS are manufactured by taking Liquid CO2 and depressurising it in a chamber or tower of a dry ice pelletiser (taking it from 13-25 bar to 1 bar). This will form 50% dry ice snow and 50% gas.
The snow is compressed and extruded through extruding plates.
We use 3 mm for dry ice pellets for blasting and 8mm pellets for cooling applications. We can also supply blocks of compressed pellets for longer shelf life.
The liquid CO2 used to produce dry ice comes either from a natural source such as underground volcanoes or as a by-product of industrial production such as fertiliser production or the process of manufacturing Ethanol or natural gas extraction.
As dry ice is generally manufactured at centralised facilities the cost of shipping can be a significant factor in costs. When transporting dry ice pellets for more than 300-500 kilometres, the time factor can have a negative effect on the dry ice resulting in poor quality for blasting. Long transport times or poorly insulated containers can quickly give losses of 10-15 % per day due to sublimation.
Dry ice manufacturers do not necessarily have dry Ice Pellets available from all their outlets. 3mm Dry Ice pellets used for blasting usually require pre–ordering to make sure that the freshest (and hardest) pellets can be delivered.
Please check with your supplier to ensure the best product.
Polar Blasting Systems is happy to work with you and facilitate the supply of pellets at the correct time and most importantly at the correct price.
Producing Dry Ice Pellets on-site
In-house production of high-density dry ice pellets offers many advantages.
- Delivery/production with short notice.
- Reduction in losses, by manufacturing only what is needed.
- Fresh pellets are better for cleaning or cooling.
The important factor when considering purchasing a dry ice pelletiser is that besides the obvious fact that you want the lowest capital cost, you also need to get a machine with well-known reliable components, with the minimum amount of maintenance cost.
Who can benefit from having in-house production of dry ice?
- Customers and users of dry ice with long transport times and large distances from suppliers.
- Customers who require short response time from placing an order to use of product.
- Customers where the pay-back calculation shows significant savings. We have a great production cost calculator available. Click here for the calculator.
A pelletiser can operate with a Liquid CO2 tank pressure from 13 to 25 bar. The piping from the tank to the pelletiser must be a cryogenic insulated piping and keeping the minimal distance from tank to the pelletiser is most important (less than 5m is ideal.)
Besides a durable 100% stainless steel cabinet, Intelblast only uses components from Danfos, Siemens and high-performance hydraulic power units as key components for the operation of the Intelblast DIP120 & 240 pelletisers.

When manufacturing dry ice the conversion of liquid CO2 to dry ice is about 2.8kg of LCO2 to produce 1kg of dry ice.
This requires that the installation of the LCO2 tank and supply piping from the tank to the pelletiser is done according to Intelblast guidelines.
When manufacturing dry ice the conversion of liquid CO2 to dry ice is about 2.8kg of LCO2 to produce 1kg of dry ice.
There are ways to greatly improve the conversion rate by using compressors to recycle exhausted CO2 gas.
This is an extremely expensive addition and unless the volumes being produced are very high then it is generally not viable.
