Comparison of normal CO₂ washer vs. supercritical CO₂ snow jet washer

Division	General CO₂ washer	Principle of supercritical CO₂ snow jet washer
Justice	Spray 55~60bar CO₂ as it is	CO₂ is boosted in pressure and sprayed in a supercritical state.
Cleaning power	It is difficult to remove foreign matter that is strongly fixed due to gas deposition.	Outstanding cleaning power compared to existing CO₂ cleaners, can remove foreign substances deposited in gas
Nozzle tip condensation	When used for a long time, there is a phenomenon that the nozzle is clogged due to dew condensation at the tip of the nozzle	No condensation
Condensation to be cleaned	Moisture is sprayed on the object to be cleaned or condensation occurs on the surface	No condensation
Air pressure	5 ~ 10 bar	More than 5~16 bar (Air Booster can step up the pressure)
CO₂ storage container	Siphon type only	Both siphon and non-siphon types can be used

Principle of supercritical CO₂ snow jet cleaner

Phase	Density (g/cm²)	Viscosity (g/cm s)
Gas	10-⁴	10-⁴
Supercritical Fluid	0.3 ~ 0.8	10-⁴ ~ 10-³
Liquid	1	10-²

CO₂ in a supercritical state has a density similar to that of a liquid state and diffusivity, surface tension, and viscosity similar to that of gaseous currents. This feature makes the mass flow of CO2 passing through the narrow capillary relatively smoother than when it is in liquid state and when dry ice particles are created by cooling due to the pressure drop (80 bar > atmospheric pressure) at the tip of the nozzle, more and more uniform particles can be made than when spraying liquid CO2 like the existing CO2 cleaners. Hence, more cleaning power.
