Dry Ice (Cryogenic) Blast Cleaning
Even though it is aggressive, dry ice blast cleaning is absolutely safe to use on production equipment, printing presses, robotic lines, electric motors, fans, walls, floors, etc. It will not etch most substrate materials being cleaned and leaves behind no additional waste or residue.
There is nothing added to the waste or contaminant being cleaned because the blast medium turns into a harmless gas (CO2 ) as it strikes the surface and evaporates into the atmosphere. And, since dry ice blast cleaning disinfects too, it is perfect for use in food and drug processing facilities -- even for cleaning containers as a last step prior to product packaging.
Replaces and is superior to sand blasting, steam/water blasting and solvents
Dry ice blast cleaning is superior to sandblasting because it does not erode or wear away the targeted surface as traditional grit media and wire brushes do. This means that surface integrity and critical tolerances are preserved and equipment will not have to be replaced due to surface erosion common with sand, glass beads and other abrasive media. Also, with dry ice blast cleaning, most equipment and machinery can be cleaned in place, which eliminates costly disassembly and reassembly.
It is also an improvement over steam and water blasting. Electrical parts and generators can be immediately put back into service without waiting to dry. Radioactive contaminate removal doesn't require large storage containers for contaminated water. Mold and mildew removal is far more complete with less chance for regeneration due to moisture. Dry ice blast cleaning removes more algae, sea slime and mussels on boat hulls than waterblasting.
Finally, dry ice blast cleaning can be used in place of many environmentally damaging solvents. These chemicals include trichlorethane, methylene chloride, perchlorethane, orhtodichlorobenzene, cresylic acid, and caustic sodas. Since dry ice evaporates completely as a gas, it leaves no waste. When dry ice blast cleaning replaces hazardous chemical cleaners the disposal costs of those chemicals are also eliminated.
Because nothing is added, there are absolutely no secondary wastes. The materials being removed generally become a light, dry dust that can easily be vacuumed and captured in filters even while the job is in process. Therefore, there is very little, if any, additional cleanup after the dry ice blasting job is completed.
Since there is rarely any need for disassembly/reassembly and no need for further cleanup after the process is completed, any required downtime is very short. The dry ice blast cleaning process allows easy, rapid access and thorough cleaning of hard-to-reach places where human hands cannot, or should not go.
Dry ice blast cleaning is a non-destructive and naturally safe cleaning/coating removal method to both humans and objects being cleaned. No chemicals, no abrasives, no electrical energy, no sparks, no heat, no high-pressure fluids, no secondary waste streams all contribute to a greatly reduced risk to the equipment being cleaned, to the personnel performing the cleaning and to our environment.
