Clean Room – Packaging in a pastry for bakery factory in Belgium
Clean room is an environment, with a low level of environmental pollutants such as dust, airborne microbes, aerosol particles, and chemical vapours. More accurately, a clean room has a controlled level of contamination that is specified by the number of particles per cubic meter at a specified particle size.
Food manufacturers aim to extent the shelf life of their products while maintaining the quality. They usually go through great lengths to achieve sterility in the product and very frequently do not pay as much attention as needed on the ambient that contains particulate and pyrogens, responsible for microbiological contamination
To achieve the desired “clean room conditions” several parameters need to be controlled .
- air purity
- air flows
- air pressurisation
- air temperature/humidity
- room design
- personnel procedures

We supply Clean room solutions based on our patented CoPlasma® system.
- CoPlasma® can be applied is areas like:
- Process rooms
- Packing rooms
- Slicing / re-packing
- Cooking rooms – fresh air supply
- CoPlasma® destroys the microorganisms transported by air flows before they risk to become contaminants for matured or fresh foodstuffs.
- The system is based on the use of cold plasma, associated with electrostatic filtration and micro-concentrations of ozone, insuring maximum hygienic safety in processing rooms, as well as in maturing, ripening, manufacturing and storage facilities.
- CoPlasma® allows a significant quality increase of the general level of hygienic safety for any produce requiring minimal thermal treatment .
- CoPlasma® increases the healthiness and safety of fresh food products
We design and supply solutions for clean areas with the following classifications:

a- All classifications based on data measured in the vicinity of exposed materials/articles during periods of activity.
b- ISO 14644-1 designations provide uniform particle concentration values for cleanrooms in multiple industries. An ISO 5 particle concentration is equal to Class 100 and approximately equals EU Grade A.
c- Values represent recommended levels of environmental quality. You may find it appropriate to establish alternate microbiological action levels due to the nature of the operation or method of analysis.
d- The additional use of settling plates is optional.
e- Samples from Class 100 (ISO 5) environments should normally yield no microbiological contaminants.
- 100 – ISO 5
- 1,000 – ISO 6
- 10,000 – ISO 7
- 100,000 – ISO 8
