In accordance with the regulatory texts cited, the solution is CE marked and delivered with a certificate of CE conformity, verified with the “anomaly detection grid” of INRS ED 4450.
Noise level < at 80 dB in operation
TheCO2 system and its storage are not classified as ICPE (French regulation : Installation Classified for the Protection of the Environmment).

Our CO2 machines comply with the following 5 directives:

  • Directive 2014/68/EU of May 15, 2014 on the approximation of the laws of the Member States concerning pressure equipment (PED: Pressure Equipment Directive).
  • Directive 2006/42/EC of May 17, 2006 on machinery, amending Directive 95/16/EC.
  • Directive 2009/104/EC of September 16, 2009 concerning the minimum safety and health requirements for the use of work equipment by workers at work.
  • Directive 2014/35/EU of February 26, 2014 on the harmonization of the laws of Member States relating to the making available on the market of electrical equipment designed for use within certain voltage limits.
  • Directive 2014/30/EU of February 26, 2014 on the harmonization of the laws of the Member States relating to electromagnetic compatibility.

A waterless process to clean up your industry


Dense Fluid Degreasing assures you of good manufacturing practices for its equipment

The manufacture of supercriticalCO2 equipment requires careful attention to detail to guarantee safety and efficiency. That’s why we’re committed to good manufacturing practices for our Dense Fluid Degreasing machines.

Quality materials: At Dense Fluid Degreasing, it’s important to use quality materials in the manufacture of our supercriticalCO2 equipment. The materials used are resistant to corrosion, pressure and high temperatures, to guarantee the durability of our machines.

Manufacturing standards: we comply with current manufacturing standards to guarantee the safety of our equipment in terms of pressure, temperature and safety.

Quality tests: We carry out quality tests before putting the equipment into service. These tests can include pressure, temperature and safety tests to ensure that the equipment is working properly.

Supercritical CO2 is a gas under pressure

Complies with :

REACH regulations
Requirements : DREAL, CARSAT occupational medicine, labor inspectorate, CHSCT, etc.

Chemically inert and stable:
Compatible with all metals + most polymers.
No bath regeneration

Between 80 and 90% of the CO2 used during the treatment cycle is recycled.

Dense Fluid Degerasing machinesare not classified as ICPE (French regulation : Installation Classified for the Protection of the Environmment) or ATEX (EXplosive ATmosphere).
Similarly, external storage of CO2 in cylinders or cryogenic tanks is not classified as ICPE or ATEX.

Frequently asked questions

Are there any regulations governing the use of CO2?

TheCO2 used in Dense Fluid Degreasing’s supercriticalCO2 cleaning and extraction machines is not produced by the machines themselves. In this sense, the machines themselves are not subject to regulations concerning pollutant discharges and emissions.

**CO2 has the advantage of being neither explosive nor flammable, unlike petrochemical solvents such as perchloroethylene or modified alcohol solvents. The use of co2 does not classify machines as ATEX (ATmosphère EXplosive).

SupercriticalCO2 cleaning machines are subject to two regulations:

  • The PED (Pressure Equipment Directive) applies. In particular, it governs the maintenance, service life and use of various pressure equipment. Periodic checks are necessary to comply with regulations. These actions are generally included in the maintenance plan proposed by Dense Fluid Degreasing to minimize the impact of these regulatory obligations. The directive also requires all persons to undergo training in the use of pressure vessels.
