Are there differences in the effectiveness of dry ice pellets vs. block dry ice granules?
Yes! The differences are significant when it comes to adapting the pellet size and aggression level to the needs of a particular application. Shaving dry ice blocks produces only a snow-like blast granule that is limited to thin layer contaminate removal. A Cold Jet® single-hose dry ice blasting system mechanically feeds a 3mm diameter pellet into the blast hose. The particular hose and blasting nozzle being used govern the actual pellet size impacting the surface.
