Supercritical CO2 Cleaning System - A gas-based solution for industrial parts cleaning and decontamination

The Solution aims at providing an efficient, non-toxic and ecological cleaning equipment to medical device, mechanic and textile industries. This cleaning equipment replaces traditional cleaning solvents such as chlorinated solvents, alcohols or water + detergents by carbon dioxide CO2, which is collected as a by-product of other industries. Once put under pressure (over 73 bar) and heated (over 31°C), this gas becomes supercritical (SC) and is a good solvent for lubricants. This solvent is able to clean like a liquid but it can also penetrate in very in small holes and cavities like a gas would do due to its very low viscosity and surface tension. DFD equipment reuses CO2 several times during cleaning thanks to a continuous internal separation system. It also recycles about 80% of the CO2 at the end of the cycle. Supercritical CO2 has also well-known "pre-sterilizing" properties.

Key features

  • 0 mg of residues of CO2 on the parts after cleaning as it is a gas
  • 100% of the extracted oil can be reused in the production process - CO2 does not degrade the oil
  • 100% saving on water consumption and no more polluted water and detergent expelled
  • 50% saving on electricity consumption, thanks to dry process at low temperature and no need of drying after cleaning

Profitability

  • OPEX divided by 2
  • Productivity raised by 10 times, compared with current cleaning technologies

Maturity Stage

  • Medium and large scale commercialization
  • Small scale commercialization
  • Initial market commercialization
  • Prototype testing in the real world
  • Prototype testing 1:1 in the lab
