Are there differences in the cleaning effectiveness of dry ice pellets vs. the granules produced by the SDI-5?
In about 75% of the applications, users do not choose dry ice media based on its cleaning effectiveness because there is little or no difference. In the remaining cases, pellets work better in some of the applications, granules in others. Generally speaking, pellets are more effective with thick hard to remove contaminants as the greater mass behind each individual particle more readily travels all the way through the contaminant to disbond it. Because the granules are smaller than the pellets, they produce a significantly greater number of surface impacts and are therefore better at removing paint. In addition, they are better for cleaning intricate patterns or tiny openings such as microvents in coreboxes. Triventek has designed a very simple accessory that allows the pellets to be quickly and easily fractured thereby simulating the cleaning effect of shaved ice.

Generally speaking, pellets are more effective with thick hard to remove contaminants as the greater mass behind each individual particle more readily travels all the way through the contaminant to disbond it. Because the granules are smaller than the pellets, they produce a significantly greater number of surface impacts and are therefore better at removing common contaminants found on switch gear and in transformer vaults.
