Component cleaning under
cleanroom conditions
You manufacture. We handle the quality-critical process step that follows. Cleaned, protected, and—depending on your requirements—documented. So your components can move directly on to the next process.
Overview
From the finished component to the defined subsequent process
The manufacturing of a component does not end with production. Before components can be used in a cleanroom, they must be cleaned, packaged under controlled conditions, and prepared in accordance with the end customer’s requirements.
That is exactly the process that comprei handles. You manufacture your components. We ensure that they are ready for the next step in the process at the specified level of cleanliness.
To this end, a dedicated, certified cleanroom was established in Villach, in southern Austria. The goal is to provide components ready for use—cleaned, packaged, and, upon request, with documented surface cleanliness.
Why is component cleaning necessary?
Before they are put into service, components go through various stages of manufacturing, transportation, and storage. During this process, particulate or film-like contaminants may form, which can impair processes, functionality, and quality in cleanrooms or controlled production environments.
Therefore, what matters is not only the removal of visible contaminants, but also achieving a defined level of cleanliness for the subsequent process.
Why companies outsource this step in the process
Not every company has the necessary cleanroom infrastructure, sufficient space, or appropriately qualified personnel for this step in the process. Often, there is simply a lack of capacity—or the company’s own resources are needed for core production.
Comprei can handle exactly this step in the process.

The comprei quality system
As a long-standing partner in the field of contamination control, we combine the expertise from Clean Services, Learning Solutions, and Clean Consumables in the area of component cleaning—along with our own cleanroom in Villach and our customary commitment to quality.
Service models – tailored to your process
Not every component and not every downstream process has the same requirements. That is why we tailor cleaning, packaging, inspections, and documentation to your actual needs. What matters is not the cleaning process itself, but what your component must be able to do afterward. Our three service models— Clean Pure, Clean Shield, and Clean Verify —provide the framework for this. We are happy to accommodate any additional customer-specific requirements.

Packaging: clean stays clean—until installation
Packaging is an integral part of the quality process. It protects the components’ achieved level of cleanliness during storage, transport by land, sea, and air, and further processing.
Depending on the project, the following factors, among others, may be taken into account:
- Cleanroom-compliant packaging
- ESD-protection
- Moisture management
- Labeling
- Customer-specific packaging requirements

Use case 1 – mechanical engineers without their own cleanroom
Initial Situation:
A mechanical engineering company manufactures precision components for a semiconductor manufacturer. It lacks the cleanroom infrastructure needed for the final step in the manufacturing process before shipment.
What "Comprei" handles:
Cleaning, packaging, documentation, and direct shipping to the end customer.
The benefit:
Your own resources remain in production. The components go directly to the next process at the end customer’s site—without any intermediate steps or additional handling.
Use case 2 – supplier with stricter documentation requirements
Initial Situation:
A supplier manufactures stainless steel components for pharmaceutical equipment. Production capacity and skilled personnel are tied up in manufacturing, while at the same time the customer requires documentation verifying the cleanliness of the delivered parts.
What "Comprei" provides:
Processing under cleanroom conditions, inspection and documented approval, as well as protective packaging tailored for transport and further processing.
The benefit:
Your own skilled staff remains on the production floor. The components arrive at the customer’s site with the required documentation and ready for assembly.
Relevant answers on the topic of component cleaning
What is meant by component cleaning under cleanroom conditions?
Parts, components, or containers are cleaned at comprei under controlled cleanroom conditions, packaged in accordance with cleanroom standards, and prepared for shipment or direct use.
How is the scope of services required for my component determined?
We always start with the component, the material, the initial condition, the subsequent process, and the customer’s requirements. We clarify these points together in advance and tailor the cleaning, packaging, inspections, and the required scope of documentation accordingly.
Can customer-specific requirements be accommodated?
Yes. Customer requirements are clarified together at the start of the project and assessed for feasibility. Cleaning, packaging, inspections, and documentation are tailored accordingly and can be customized as needed.
What happens if a discrepancy is found upon delivery or during processing?
Any irregularities are not simply overlooked. They are evaluated and documented. Depending on the nature of the deviation, the next steps are determined and, if necessary, coordinated with the customer before processing continues.
What documentation will I receive for my order?
The scope of documentation depends on the agreed-upon service model and the actual requirements. It ranges from basic, streamlined documentation to comprehensive process, test, and verification documents.
How does the delivery of the components work?
Can both individual parts and recurring quantities be processed?
Yes. We process individual parts and small quantities as well as recurring orders. The only requirement is that the defined minimum order value be met. For recurring orders, processes and procedures can be standardized accordingly and tailored to the specific requirements.
How much does it cost to clean components?
Costs depend on the component, material, size, and geometry; the initial condition; the quantity; and the requirements for cleaning, packaging, inspection, and documentation. Once these points have been clarified, we will prepare a quote tailored to your specific needs.
