How Dry Ice Blasting Works

Dry Ice Blasting is the most Environmentally Friendly Surface Restoration process used for cleaning machinery, structures, or objects. Its unique ability to sublimate (turn from solid to vapor without going through the liquid state) means there are no by-product or secondary wastes created resulting in minimal cleanup.

This is very significant because Dry Ice Blasting eliminates the use of harmful chemicals, as well as the cost of hazardous waste disposal making it your safest and most cost effective environmental site cleaning option.

  1. Energy Transfer (Dry Ice Pellet Kinetic Energy)

Using Pressure to  fire Dry Ice Pellets out of the nozzle and hit the substrate (surface) to knock the contaminants off. Dry Ice is ‘soft’ so no abrasion occurs. This is the first means of cleaning.

  1. Temperature (Thermal Shock Effect)

The extreme cold of the dry ice pellets (-79 degrees) hitting the surface creates a micro thermal shock between the surface and the contaminant. This creates stresses, shrinking and cracking of the contaminant further dislodging them from the substrate. This extreme cold also sanitizes a surface which is valuable in food processing.

  1. Gas Pressure (Sublimates)

The third means of cleaning is the sublimation. As the dry ice pellet impacts with the surface, it expands and converts to a harmless gas, expanding 500 times beneath the contaminant.  The ‘explosion’ blasts off the contaminant which typically falls to the floor.  As the dry ice disappears back into the atmosphere only the dislodged contaminant needs to be disposed of.

 

Dry Ice Blasting applications:

  • Surface preparation-Removes oils, grease, wax prior to painting
  • Equipment maintenance-Film, grease, light corrosion, coatings
  • Blast Cleaning-Dirt, mould, paint, tar, adhesives, and coatings
  • Stone and Brickwork Cleaning-Graffiti removal, paint removal, brick restoration
  • Historical Restoration-Environmental stains, grime, coatings, and surface dirt
  • Concrete-Coatings, paint, and sealer removal
  • Bitumen-Equipment, piping, stairs, tanks, tankers
  • Structural steel cleaning-can clean equivalent to an SSPC 1 level wash down surface preparation
  • Industrial coatings spraying to agreed specification

Benefits to using our Dry Ice Blasting Service:

  • No secondary waste-eliminating clean up costs and disposal fees
  • Dry process– since the dry ice sublimates you can clean in place, safe for all electrical applications
  • Environmentally Friendly-uses recycled carbon dioxide
  • Minimal containment and cleanup saving you money
  • Faster and more effective-compared to manual cleaning with solvents
  • Non-Abrasive-wont damage sensitive parts, sensors, wiring, electronics, etc.
