Frequently Asked Questions
​# General Questions
What is dry ice blasting?
Dry ice blasting is an environmentally friendly cleaning method that uses solid CO2 (dry ice) pellets accelerated in a pressurized air stream to clean surfaces. The process is non-abrasive, non-conductive, and leaves no secondary waste, as the dry ice sublimates upon impact.
How does dry ice blasting work?
Dry ice blasting works through three primary mechanisms: kinetic energy, thermal shock, and sublimation. The dry ice pellets are propelled at high speeds, impacting the surface and dislodging contaminants. The extreme cold causes the contaminants to shrink and lose adhesion, while the sublimation of dry ice creates a micro-explosion that lifts the contaminants away.
What are the benefits of dry ice blasting?
Benefits include: non-abrasive cleaning, no secondary waste, environmentally friendly with recycled CO2, reduced downtime by cleaning in place, safe for electrical components, and non-toxic, non-flammable operation.
Is dry ice blasting safe?
Yes, when proper safety precautions are followed. Operators should wear appropriate personal protective equipment (PPE), including hearing protection, eye protection, gloves, and closed-toed shoes. Adequate ventilation is necessary to prevent CO2 buildup
What industries use dry ice blasting?
Industries such as manufacturing, automotive, food processing, aerospace, electronics, and restoration use dry ice blasting for cleaning and maintenance, and many more.
What types of surfaces can be cleaned with dry ice blasting?
Dry ice blasting can clean metals, plastics, rubber, glass, concrete, and more, without causing damage.
# Equipment and Technical Questions
What equipment is needed for dry ice blasting?
You need a dry ice blasting machine, compressed air source, blast hose, nozzle, and a supply of dry ice pellets.
Where can I purchase dry ice pellets for blasting?
Dry ice can be bought from industrial gas suppliers or specialized distributors. It's important to use pellets designed for blasting. We recommend 3mm
How much does dry ice cost?
The cost varies by region and supplier. Contact local suppliers for current pricing.
How do I store dry ice?
Store dry ice in an insulated container to slow down sublimation. Do not store in airtight containers as pressure can build up.
What air pressure is required for dry ice blasting?
The required air pressure depends on the specific machine and application. Generally, pellet systems require a range between 3 to 8 bar
Can dry ice blasting remove paint?
Yes, it can remove failing paint and surface coatings. For strongly bonded paint, additional methods may be needed.
Can dry ice blasting remove rust?
It can remove surface rust and oxidation but may not be effective for heavy rust. For deep rust removal, other methods might be necessary.
Is dry ice blasting effective for mold removal?
Does dry ice blasting leave any residue?
Yes, it can remove mold spores and is often used in remediation because it's chemical-free and doesn't add moisture.
No, the dry ice sublimates upon impact, leaving only the removed contaminants behind.
Can dry ice blasting be used on electrical equipment?
Yes, since it's a dry process and non-conductive, it's safe for cleaning electrical components without risk of short circuits. It is of course really important to shutdown the power,
What is the environmental impact of dry ice blasting?
It's environmentally friendly as it uses recycled CO2, produces no secondary waste, and eliminates the need for chemicals or water.
How do I choose the right dry ice blasting machine?
Consider factors like the type of applications, required pressure and flow rates, portability, and budget. Consult with suppliers for recommendations based on your specific needs.
