Some of the Dry-Ice Blasting Users

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

Latest Technology

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.

• 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

Equipment cleaning

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

Cleaning Method Comparison

Issue Traditional Dry-Ice Blasting

Equipment

Downtime

Cleaned in dedicated cleaning area; Disassembly / reassembly; Drying time required

Equipment can be cleaned in place; Dry process-equipment restart immediately after cleaning

Hazardous

Waste

Intensive hand scrubbing; Lengthy cleaning; Follow-up cleaning-up can be lengthy

Dramatically reduced-often completed in a quarter of time or less

Quality Cleaning Poor to average Excellent

Equipment Damage

Grit abrasions; Grit contamination; movement of equipment to and from cleaning area

No equipment damage; Preventive maintenance very realistic as labour hours are significantly reduced

Safety Health treats from solvents; Water based cleaning pose hazards around electrical equipment

Standard safety precautions; Dry process-safe around electrical equipment

Cost Cleaner becomes additional hazardous waste; Expensive solvents; Additional labour

Minimal - Cost of Dry-Ice
