Dry Ice Cleaning
CO2 (Dry ice) Blasting
CO2 Blasting is the rising star in industrial cleaning applications. It is an efficient and cost-effective way for industries to maximize production capability and quality.
What is Dry Ice Blasting?
It is similar to sand blasting, in that the medium is accelerated in a pressurized air stream to impact a surface to be cleaned or prepared.
Instead of using hard coarse media to grind on a surface (and damage it), dry ice blasting uses soft dry ice, accelerated at supersonic speeds, and creates mini-explosions on the surface to lift the unwanted item off the underlying substrate.
Dry ice blasting has many unique and greater benefits over traditional blasting media. Dry ice blasting:
- is a non-abrasive, nonflammable and nonconductive cleaning method
- can be used for many general cleaning applications
- is environmentally-friendly and contains no secondary contaminants such as solvents or grit media
- can be used without damaging active electrical or mechanical parts or creating fire hazards
- can be as gentle as dusting smoke damage from books or as aggressive as removing weld slag from tooling
- allows most items to be cleaned in place without time-consuming disassembly
- can be used to remove production residues, release agents, contaminants, paints, oils and biofilms
- is clean and approved for use in the food industry
Dry ice blasting uses compressed air to accelerate frozen carbon dioxide (CO2) "dry ice" pellets to a high speed. A compressed air supply of 80 PSI/50 scfm can be used in this process. Pellets are made from food grade carbon dioxide that has been specifically approved by the FDA, the EPA and the USDA. Dry ice pellets can be made on-site or supplied. Carbon dioxide is a non-poisonous, liquefied gas, which is both inexpensive and easily stored at work sites.
