Dry ice cleaning offers comprehensive cleaning benefits over traditional methods in an environmentally friendly way.
The EPA, FDA, and USDA recognize dry ice as an acceptable material in cleaning methods.
From gently restoring smoke damaged books, to cleaning multimillion-dollar production equipment in place, there are numerous benefits to dry ice cleaning.
How it works:
Dry ice (solid CO2 with a low temperature of -109°F) is accelerated at supersonic speeds to create thermal impact that lifts surface contaminants from substrates without causing damage. The CO2 then sublimates (vanishing into thin air), leaving no secondary waste.
Instead of abrasive media to grind surfaces (sand, bead, and soda blasting) dry ice is a medium that is natural and non-additive. This method cleans items that previously seemed impossible, in a very environmentally friendly way.
Completely safe and non-toxic, dry ice does not produce or add CO2 to the atmosphere – which is why using dry ice is considered “carbon neutral” and environmentally responsible.
The natural sublimation of dry ice particles eliminates the cost of collecting the cleaning media for disposal. Containment and collection costs associated with water/grit blasting procedures are also eliminated. Additionally, because CO2/dry ice blasting systems provide on-line maintenance capabilities for production equipment (on-line cleaning), time-consuming and expensive detooling procedures are kept to a minimum. Dedicated cleaning cycles are no longer required; instead preventive maintenance schedules can be adopted, which allow for equipment cleaning during production periods. As a result, throughput is increased without the addition of labor or production equipment.
Extension of Equipment's Useful Life
Unlike sand, walnut shells, plastic beads and other abrasive grit media, dry ice particles are non-abrasive. Cleaning with dry ice will not wear tooling, texture surfaces, open tolerances, or damage bearings or machinery.
Minimized Substrate Damage
Unlike steam or water blasting, CO2/dry ice blasting is a dry process will not damage electrical wiring, controls or switches. Also, any possible rust formation after cleaning is far less likely with dry ice blasting than with steam or water blasting.
Carbon dioxide is a nontoxic element that meets EPA, FDA and USDA industry guidelines. By replacing toxic chemical processes with CO2/dry ice blasting systems, employee exposure and corporate liability stemming from the use of dangerous chemical cleaning agents can be materially reduced or eliminated completely. Since CO2 gas is heavier than air (CO2 gas displaces oxygen), care must be taken if blasting in enclosed areas or down in a pit.
