Dry Ice Blasting Benefits
Dry Ice Blasting | Benefits | Uses | Other Applications |
Dry ice blasting benefits can be broken down into seven general areas. They are as follows:
Benefit #1 - Decreased Downtime through Cleaning In-Place
Typical cleaning procedures require that equipment be disassembled and moved to an assigned area for proper cleaning. That is not the case with dry ice blasting. Equipment can be cleaned in-place and hot in most situations. Because of that, many time-consuming, labor-intensive steps that were required with other methods such as sand blasting can be eliminated including:
- Cool down
- Disassembly
- Transport of the equipment to and from a dedicated cleaning area
- Reassembly
- Reheating time
Dry ice blasting can shorten the downtime for cleaning from days down to hours.
Benefit #2 - Faster and More Thorough Cleaning
With dry ice blast cleaning, a superior clean can be achieved while reducing hours when compared to scrubbing with abrasive pads or wire brushes. A tremendous labour savings is accomplished. In addition, the CO2 blast method cleans in crevices that can't be reached by hand. As a result, equipment runs more efficiently and potential leaks are revealed possibly preventing major system failures.
Benefit #3 - Elimination of Equipment Damage
Dry ice blasting often eliminates equipment damage. Cleaning methods such as sandblasting leave an aggressive and abrasive effect on the surface. They can actually remove part of the surface, changing the surface structure considerably. Dry ice is non-abrasive to surfaces and does not change a surface's structure. It lifts the contaminants away. Secondly, because equipment can now be cleaned in place, potential damage from moving equipment to and from a dedicated cleaning area is also eliminated.
Benefit #4 - Reduction or Elimination of Solvents
Dry ice blasting uses no solvents, but instead uses harmless CO2
pellets. This can be a critical need for certain companies in order to
comply with environmental regulations or to improve worker safety.
There are no issues pertaining to toxicity.
Benefit #5 - Reductions in Waste Disposal
With other cleaning methods, whether solvents, sand blasting or some other means, the cleaning agent becomes a secondary contaminant and must be disposed of as toxic waste along with the primary contaminant. However, with dry ice blast cleaning because the CO2 pellet vaporizes upon contact, the only waste created is the contaminant itself. This alone can result in significant waste reduction.
Benefit #6 - Increased Safety
Dry ice blasting pellet is non-toxic, non-hazardous creating advantages to the environment, your employees, and production facility:
- No secondary waste
- Safe for the environment
- Safe for employees
- Safe for end products
- Safe for equipment
Benefit #7 - Inhibits bacteria & mold growth
Dry ice is a natural bacterial and fungal growth inhibitor because it's low temperature of -78.5 °c kills bacteria and mold [fungi] upon contact. When you clean with dry ice blasting, you're also disinfecting.
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 |
Cleaner becomes and treated as a secondary contaminant |
No additional contaminant; Dry ice sublimates with contact with targeted surface |
|
Labour Hours |
Intensive hand scrubbing; Lengthy cleanings; Follow-up cleaning-up can be lengthy |
Dramatically reduced - often completed in a quarter of time or better |
|
Quality of Cleaning |
Poor to average |
Excellent |
|
Potential 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 less |
|
Safety |
Health threats from solvents; Water-based cleaning pose hazards around electrical equipment; Threats to environment |
Standard safety precautions; Dry process - safe around electrical equipment |
|
Cost |
Cleaner becomes additional hazardous waste; expensive solvents; Additional labour |
Minimal - cost of dry ice |
