  • Absolute cleaning: With technology that uses dry ice at high pressure, this CO2 dry ice machine can clean and maximize the surface of hard-to-reach nooks , even stains, long-term residue on the surface
  • Do not need to use cleaning chemicals: When using a CO2 dry ice machine, you will not need other cleaning chemicals. This keeps you away from potential hazards.
  • No damage to the surface of the cold storage: at the molecular size, dry ice can clean the surface as much as possible.
