Are you facing a tough cleaning challenge? Maybe you need to remediate fire damage, deal with mold, or clean electrical equipment or HVAC coils with a minimum of operations disruptions and revenue loss. Sandblasting may seem like your only option, but in many cases, dry ice cleaning might prove to be just what you’re looking for.
Sandblasting requires the use of an abrasive material, accelerated at high speed towards the surface you are trying to clean. The sand dislodges the unwanted material, and then collects, along with the blasted-away waste. In many cases, this sand-waste combination requires extensive cleaning and may even be toxic, requiring special waste removal methods. Dry ice solves this! Because dry ice is frozen carbon dioxide, after it has been blasted at the surface being cleaned, it simply sublimates directly into a gas, leaving no wet or gritty residue behind. All that needs to be removed at the end of blasting is the waste which has been cleaned from the surfaces. No secondary waste disposal means less work and cheaper cost!
When you’re dealing with sensitive surfaces, sandblasting may seem like a necessary evil. In many cases you may wish to avoid surface roughness once you are finished with your necessary cleaning. Because dry ice pellets are “soft” compared to sand, you can use it on more delicate materials. However, the lack of abrasiveness with dry ice blasting does mean that for applications like removal of grease and oil, and paints from some surfaces, it may be less effective than sandblasting.
One of the downsides of sandblasting is that it produces fugitive dust, which is both toxic, and dangerous for human lungs, due to the microparticles produced. Dry ice, however, produces only carbon dioxide gas as a by-product, so as long as the area is well-ventilated, no health concerns exist. This improves both worker and operator safety. The words “carbon dioxide” may bring up environmental concerns, but the gas which we use has been ‘recycled’ from the emissions of other industries, thus resulting in no net environmental impacts from the use of the gas.
Did you know that dry ice cleaning is safe to use in commercial kitchens and food processing plants? Because it doesn’t leave behind any residue, it is a food-grade cleaning method!
You can even use dry ice blasting in environments where electrical conductivity is a concern. Because no liquid is produced as a byproduct – just gas – dry ice cleaning is non-conductive and perfectly safe for electrical equipment.
Dry ice blasting can often even be done without disassembling the equipment being cleaned! Ultimately, when deciding on what method of blasting is most directly applicable to your needs, you need to take into account health, waste production and removal, conductivity, and abrasiveness.
