Dry Ice Blasting: A Quick Read Guide

Dry Ice Blasting: A Quick Read Guide

Dry ice blasting is a cleaning method that has revolutionised various industries with its efficiency, environmental benefits, and non-abrasive process.

What is Dry Ice Blasting?

Dry ice blasting, also known as CO2 blasting, or cryogenic blasting is a cleaning technique that utilises dry ice pellets (solid carbon dioxide) as the blasting medium. Unlike traditional abrasive cleaning methods, dry ice blasting is non-abrasive and non-toxic. The process involves propelling dry ice pellets at high speeds using compressed air. When the pellets strike a surface, they sublimate (transition from solid to gas) upon impact, effectively lifting contaminants off without damaging the underlying material.

How Does Dry Ice Blasting Work?

The process of dry ice blasting can be broken down into three primary mechanisms:

  1. Kinetic Energy: The high-speed impact of dry ice pellets helps dislodge contaminants from surfaces.
  2. Thermal Shock: The extremely low temperature of dry ice (-78.5°C or -109.3°F) causes contaminants to contract and become brittle, facilitating their removal.
  3. Sublimation: Upon impact, dry ice pellets instantly convert from solid to gas, expanding up to 800 times their original volume. This rapid expansion helps lift contaminants away from the surface.

Applications of Dry Ice Blasting

Dry ice blasting is incredibly versatile and can be used across various industries. Here are some common applications:

1.Industrial Cleaning

  • Equipment and Machinery: Removes grease, oil, and other residues from machinery without disassembling equipment.
  • Production Lines: Cleans conveyors, moulds, and other components, reducing downtime.


2. Automotive Industry

  • Engine and Component Cleaning: Cleans engines, transmissions, and other components without damaging sensitive parts.
  • Restoration: Removes paint, rust, and grime from vehicles, making it ideal for restoration projects.


3. Food and Beverage Industry

  • Sanitisation: Effective for cleaning food processing equipment, reducing bacteria and contaminants without leaving residue.
  • Packaging Lines: Cleans packaging machinery, maintaining hygiene standards.


4. Aerospace and Aviation

  • Maintenance: Cleans aircraft parts, engines, and exteriors, preserving the integrity of materials.
  • Composite Materials: Safely removes contaminants from composite materials used in aircraft construction.


5. Electronics and Electrical Industry

  • Circuit Boards: Removes flux, dust, and other residues from circuit boards without damaging delicate components and is safe due to it being non-conductive. .
  • Switchgear and Transformers: Cleans electrical equipment, reducing the risk of shorts and malfunctions.


6. Fire and Mould Remediation

  • Smoke and Soot Removal: Effectively cleans soot and smoke damage from structures after fires.
  • Mould Remediation: Removes mould from various surfaces including timber framing, without spreading spores, ensuring thorough decontamination.


7. Historical Restoration

  • Delicate Surfaces: Cleans stone, brick, and other historical building materials without causing damage, preserving the integrity of heritage sites.


Benefits of Dry Ice Blasting

  • Non-Abrasive: Safe for delicate surfaces and components, preventing damage.
  • Time-Efficient: Reduces downtime by allowing cleaning in-place without disassembly.
  • Cost-Effective: Minimises labour and disposal costs due to its efficient cleaning process and lack of secondary waste.


Dry ice blasting is a powerful and versatile cleaning method that offers numerous benefits over traditional techniques. Its ability to clean effectively without damaging surfaces or creating secondary waste makes it an invaluable tool across various industries. Whether it is industrial equipment, food processing machinery, or historical restoration, dry ice blasting provides a safe, efficient, and more sustainable solution.
