Planning and consulting
The key ingredient for a successful project:
​
a professionally executed, conceptual and constructive work
Today, hardly any branch of industry can do without the use of cleanrooms. Whether in the manufacture of pharmaceutical products, medical technology, cosmetics, food, or microelectronics, nanolithography, automotive engineering, design parts and coated surfaces, cleanrooms are used.
​
This is because cleanrooms protect products and processes from various environmental influences. They create a defined space in which work can be carried out under hygienically optimal (clean) conditions. Even the smallest parts can be produced sterilely and safely. By investing in cleanrooms, companies increase the quality of their products and enable an expansion of their own product range, which leads to a market advantage over the competition.
Before starting to plan a cleanroom, it is important for both you and us to think about the implementation criteria listed here
- Definition of the areas (e.g. clean room, airlock area)
- Area of the individual areas (dimensions)
- Machines and equipment in the cleanroom
- Number of people in the cleanroom and their working hours
- Material and product throughput (quantities)
- Zone concept in relation to products and work processes
- Consideration of room air contamination (particle and/or germ carriers). Actual and target.
- Humidity, temperature etc. Actual and target
Conception
A conceptual design is a vision of future manufacturing on paper. It is much easier and less expensive to plan everything in advance, to select and arrange equipment, to position space properly, to eliminate cross-contamination and unnecessary personnel movement, to place communication and power connection points rationally and economically, and to incorporate fire and health and safety measures into the project. Reworking a poor job is much more expensive than a well thought-out project design.
The conceptual design is the specification for the architectural and structural design and includes:
Structural concept
Concept of the plant, including room layout, with specification of cleanliness classes and description of the structures of the production rooms.
Production process concept
Include equipment location plans, list and characteristics of major process equipment.
Storage space concept
Quality control concept
Energy supply concept
Ventilation and climate concept
HVAC
Communication concept
Security concept
Occupational safety and industrial hygiene
Typical mistakes when creating a design
Overlap of the "paths" of raw materials, personnel, products and waste
1. The size and location of, for example, a picking area does not allow goods to be assembled without the risk of cross-contamination.
2. There are no quarantine areas or the area of the areas is insufficient;
No space for accumulation and temporary storage of production waste.
3. Placement of equipment with different effects in the same room (e.g., an air dryer and a granular mixer).
4. Intersection of paths of raw materials (semi-finished) with finished or unpackaged products.
​
5. Intersection of clean and dirty materials.
6. Intersection of "clean" and "dirty" personnel.
​
Inconsistency of the ventilation concept with the intended use.
1. Recirculation at the point where the inlet should be.
2. Inconsistency of the cleanliness class with the operations to be performed (e.g., capping in area "B", product preparation for final sterilization in area "D").
3. Insufficient air exchange ratio (e.g. critical room or room with increased heat generation).
