3. Some of the Dry-Ice Blasting Users

4. What is Dry-Ice Dry ice, at -78.6°C, is an excellent, lightweight, non- mechanical, non-wetting cooling agent made by taking liquid carbon dioxide from a pressurized storage tank. Expanding it at ambient pressure to produce snow. The snow is then compressed with a die to make hard pellets. It has nearly twice the cooling power of water ice by weight and three times by volume. To be used for Dry-Ice Blasting

5. Dry-Ice Blasting Latest Technology

6. What is Dry-Ice Blasting Dry ice blasting is a new cleaning process using solid CO2 pellets (convert directly from a solid blast pellet to a vapor) With the dry ice blasting process, CO2 particles are propelled at supersonic speed, impacting and thus cleaning a given surface The particles are accelerated by compressed air, just as with other blasting methods.

7. Paint Removal (paint & printing industries) Rubber and plastic mould cleaning (even when the mould is still in hot condition) (manufacturing, moulding, rubber industries) Production machine & production line cleaning & maintenance ( manufacturing, pharmaceutical industries) Carbon removal, glue removal, rust removal, oil removal, grease removal Mixer and machinery cleaning (Bakeries & food industries) Injection moulding, Blow moulding & Compression moulding cleaning (Automotive industries) Die-casting Electrical – Live electrical switchgear Dry-Ice Blasting can be used for

13. Benefits Of Dry Ice Blasting Technology Decreased downtime through cleaning in-place, labor necessity for disassembly, transport of the equipment to and from the designated cleaning area, can be cleaned in-place and hot in most situations and reduce cleaning time Dry ice blasting provides a superior cleansing in less time than scrubbing with abrasive pads or wire brushes, no chemical needed Elimination of equipment damage, Dry ice is non-abrasive and does not change a surface’s structure Reductions in waste disposal because dry ice pellets vaporize upon contact, this alone can result in significant waste and cost reduction non-secondary waste disposal Increased safety. Dry ice blasting pellets are non-toxic and non- hazardous, which benefits the environment and eliminates the risk of contamination for employees, end products and equipment
