Operation of the machines
The Dense Fluid Degreasing machines are controlled by a Siemens PLC and are fully automated. This control system allows remote maintenance and monitoring
Machines adapted to each environment
The Dense Fluid Degreasing machines are designed so that the cleaning autoclave(s) are several tens of meters away from the main body of the machine. This machine body can be located in a technical room.
One machine body can operate between 1 and 4 autoclaves, thus increasing production rates.
The autoclave(s) can be located in clean rooms (grey or white) or in different rooms.

Adapted sizing
Dense Fluid Degreasing adapts its autoclave capacity standards according to the production rates to be respected and the size of the parts to be treated. Dense Fluid Degreasing autoclaves range in size from 4L to 550L.
Working pressures can range from 100 to 300 bar.
Contrôle commande par automate programmable
Toutes les machines Dense Fluid Degreasing sont équipées d’un automate avec écran de contrôle Siemens. L’écran tactile permet le pilotage et la maintenance de la machine en physique ou à distance.

Is supercritical CO2 the only degreasing agent in the machine?
For now, yes. It is important to know that the program of the machine will be adapted to the degreasing of each type of part: washing time, pressure and temperature will be adjusted to achieve the cleaning result, as well as the agitation, oscillation or the addition of ultrasound in the washing autoclave.
In special cases, co-solvents such as water or ethanol, as well as additives such as surfactants or “complexing” agents may be used. We are currently working on the research of bio-sourced and biodegradable additives to complement the action of CO2.
Can CO2 alone remove all types of lubricants?
According to our numerous tests, CO2 alone is as effective on water soluble cutting oils as on mineral oils. However, some remain poorly soluble in CO2. For this reason, our research program continues with the evaluation of surfactant additions.
Do operating personnel need special training to operate a DFD machine?
As with all new equipment, the installation of a DFD machine will be subject to appropriate on-site training. DFD will be able to instruct personnel on maintenance and production processes, as well as on the use of autoclaves and pressure equipment and the operation of the control panel
