Tecnología de limpieza innovadora basada en CO2 supercrítico para industrias mecánicas


Oferta Tecnológica
Una empresa francesa ha diseñado un equipo de limpieza para desengrasado eficiente y eliminación de partículas mediante CO2 supercrítico. Esta tecnología exclusiva combinada con su experiencia ofrece a fabricantes industriales una alternativa competitiva y respetuosa con las normas medioambientales si se compara con los procesos basados en detergentes y disolventes empleados para limpiar piezas mecánicas en la industria. El objetivo es ofrecer una tecnología eficiente que se adapte a procesos industriales con el mínimo coste posible. La empresa busca socios industriales con el fin de desarrollar el equipo de limpieza y establecer acuerdos de cooperación técnica.


A French company is looking for technical cooperation agreement for their innovative cleaning technology using supercritical carbon dioxide dedicated to mechanical industries
The French company has designed a cleaning equipment for an efficient degreasing and particles removal using supercritical CO2. This exclusive technology, combined with the expertise, offers to industrial manufacturers an alternative, competitive and respectful of environmental standards, compared to detergent or solvent processes used for mechanical parts cleaning in industry. The company is looking for technical cooperation agreement to develop the cleaning equipment with industrials.
The French SME has been created in 2012 in order to develop and market an innovative concept of an energy-guzzling, safe and environmental friendly cleaning equipment, after many years of research and development with French laboratories from the nuclear and mechanical industries and a gas supplier.
This new cleaning process is based on the use of supercritical carbon, replacing current polluting solvents condemned by REACH regulation.
The company designs, manufactures and sells machines for cleaning mechanical parts or fabrics. The purpose is to provide an efficient technology perfectly adapted to industrial processes at the lowest global cost. The company offers a safe and environmental friendly alternative technology to current polluting and energy-guzzling cleaning processes. This process doesn´t require water, decreases by 50% energy consumption, and doesn´t impact air quality.
Supercritical carbon dioxide has a density close to liquids and diffusivity close to gases. It allows to clean in depth pieces:
- All metallic materials without oxidation and most of polymers
- With any shape, even complex with small interstices and blind holes
- Any size, from very small pieces (watchmaking, electronics, bar turning and high precision parts) to bigger parts (aeronautics and car industries)
The French SME possesses a R-Y-D machine able to perform cleaning tests at a pilot scale. This machine has got multiple options and is adapted to different cases. Hence, the company is looking for industrial partners who want to change their cleaning machines to environmentally friendly machines.
The technical cooperation is mainly centered on support for industrials in their new cleaning processes and finally finished on a dedicated equipment.
Advantages and Innovations:
This innovative solution is meant to replace current machines using tetrachloroethylene, trichloroethylene, dichloromethane, oil derivatives and water detergents. The machines are supplied with liquid CO2, not produced specifically for this process but recovered from industrial activities and purified. CO2 is then heated and pressurized to reach the supercritical stage, CO2 becomes as dense as liquids and as diffuse as gases: a green solvent to allow efficient cleaning.
The advantages of CO2 are multiple: it´s not corrosive, not harmful, not irritant, not carcinogenic, neither flammable nor combustive. This process allows to get rid of polluting and harmful solvents and to suppress water consumption. No more needs of cleaning and rinsing successive bins, there is only one equipment. The process is more efficient.
The machines are also flexible in their use (settings of pressure, temperature, cleaning time can be adapted to most of the requirements, additional ultra-sounds or agitation can be added if required). Currently, soluble oils are the most suitable to dense fluid but primary oils can also be treated.
Stage of Development:
Already on the market

Partner sought

Type and Role of Partner Sought:
The French SME is looking for partners in the mechanical industry sector (SME - more than 10 employees, mid-caps and large industries) with a cleaning issue concerning mechanical parts.
Partners should be ready to cooperate on a technical base and to provide samples of their products to clean.
The cooperation would consist in several steps, from defining the cleaning specifications of the partner, to the optimization of cleaning parameters and proposal of a specific equipment.
The technical cooperation agreement is the first step of the partnership.
