eCO2 cleaning process

The parts to be cleaned are loaded into a suitable basket and introduced into the cleaning chamber. 
The CO₂  flows at the required temperature and pressure through the cleaning chamber and drags the dissolved dirt together with the CO₂  out of the cleaning chamber, where the separation takes place into gaseous CO₂  and waste. Depending on the dirt type and geometry of the parts to be cleaned, rotating baskets and / or ultrasound are used. For higher levels of CO₂  consumption, it is economical to recycle the separated gaseous CO₂  (closed loop).

Key points of the eCO₂ -Process

• Removal of oils and fats using CO₂  as solvent
• Excellent access to smallest capillaries and to difficult surfaces due to the
  exceptional fluidity of CO₂
• Uniform exposure of the parts to be cleaned due to controlled rotation of the basket
• Separation and removal of components that are insoluble in CO₂  due to ultrasound
• In closed loop operation mode, cleaned CO₂  can be reused for the cleaning process
• The bactericidal effect of eCO₂  process increases the product safety significantly, which is desirable especially for medical application
• No harmful solvent vapours (respiratory protection)
• No aggressive / corrosive cleaners (skin and eye protection)
• Low power consumption - no drying of the parts necessary
• No flammable solvents and expensive waste disposal

Application fields of eCO₂ -cleaning process

• Medical devices, dental, optical, aerospace, precision mechanics
