At PSB GmbH, we understand that implementing computers in cleanroom environments requires a precise balance of advanced engineering and stringent standards. Cleanrooms, especially within medical and industrial settings, pose unique demands such as controlling particulate contamination, ensuring consistent system operation in various environmental conditions, and complying with exacting regulatory requirements. Our team leverages over 30 years of experience in designing PC-based solutions that seamlessly integrate into environments with elevated cleanliness expectations. This includes systems with hermetically sealed housings, specialized filtration, and robust ingress protection to safeguard both sensitive processes and device longevity. We approach each project independently, focusing on bespoke configurations that address the specific technical and operational challenges presented by cleanrooms. By partnering closely with our clients, we ensure that every solution precisely aligns with their needs and offers enduring reliability.
Herausforderungen beim Computereinsatz im Reinraum
Using computers in cleanrooms introduces several unique challenges, not least the risk of contamination that IT equipment can pose in ultra-sensitive environments. Cleanrooms—utilized in pharmaceutical, food, medical, and semiconductor manufacturing—must adhere to stringent regulatory requirements like GMP and FDA guidelines. Standard computer hardware, with its fans, crevices, and heat dissipation needs, can easily become a source of particulate and microbial contamination. This makes the deployment of a Reinraum-Computer or PC for Reinraum radically different from standard office or even rugged industrial computing.
Typical issues include:
- Contamination by Airflow and Particles: Fans and unsealed housings can distribute dust, pathogens, or other contaminants, countering the very purpose of a clean environment.
- Cleaning Limitations: Standard PCs lack smooth, waterproof surfaces. This makes them extremely difficult to sanitize properly, especially when harsh disinfectants or wipe-downs are required.
- Material Incompatibility: Common plastics and painted metals can degrade under frequent chemical cleaning, leading to flaking, corrosion, and further particle release.
- Regulatory Compliance: Achieving certifications for GMP or FDA readiness requires computers to meet strict guidelines regarding materials, operation, and cleaning.
Given these hurdles, every Reinraum PC must be evaluated for its impact on cleanliness, durability, and compliance. For an in-depth look at robust PC concepts, see Fanless Industrial PCs: Reliable & Robust Solutions.
Lösungsansätze: PC-Einhausungen vs. spezialisierte Reinraum-PCs
PC-Einhausungen: Kostengünstiger Einstieg
The most basic approach to cleanroom IT is the use of PC-Einhausungen—enclosures that house a standard PC within a protective shell. Made from materials like stainless steel (V2A or V4A alloy), these enclosures feature IP65 or even IP66/IP69K ingress protection, and can be custom designed with windowed sections for displays and inputs.
PC enclosures provide a comparatively economical solution, making them ideal for upgrading existing hardware. However, their drawbacks include potential thermal problems due to insufficient passive cooling and maintenance complexity when hardware needs to be accessed or replaced.
- Advantages: Low initial cost, re-use of existing PCs, upgrade flexibility.
- Disadvantages: Bulky, cleaning can be challenging (especially joints and seals), and not always suitable for the highest cleanroom classes.
For choosing appropriate enclosures or workstations, IP-Protected Workstation: Types & Selection Guide offers a comprehensive overview.
Spezialisierte Reinraum-Computer: Maximale Hygiene & Sicherheit
Unlike protective enclosures, dedicated Reinraum-Computer are purpose-built for rigorous cleanroom operations. Such systems employ seamless stainless steel casings with fully flush, screwless (fugenlos, splitterfrei, schraubenlos) designs to eliminate dirt traps. Their construction uses high-grade alloys (V2A/V4A) and sometimes PMMA components to maximize smoothness and avoid particles sloughing from the material surface.
Moreover, these units are often completely fanless, leveraging passive cooling technologies to prevent air disturbance and the associated risk of contamination. Integrated touchscreens for cleanroom use further reduce the need for mechanical keyboards or mice, minimizing additional contamination points.
- Advantages: Total hygienic design, meets highest cleanroom classes, easy cleaning, minimal maintenance.
- Disadvantages: Higher investment, but offset by compliance and reliability benefits.

Wesentliche Anforderungen an Reinraum-Computer (Material, Design, Schutzklassen, Kühlung, Bedienung)
Material: Edelstahl und splitterfreies Design
Reinraum-Computer are typically made from V2A or V4A stainless steel. These alloys provide both corrosion resistance (required for frequent cleaning), and a non-porous surface that resists microbial growth and is easy to sanitize. For screens or viewing windows, durable and chemically resistant PMMA (polymethyl methacrylate) is often employed.
Design: Hygienic and Seamless Construction
Fugenloses (seamless), splitterfreies und schraubenloses (screwless) housing is vital for cleanroom PCs. Rounded corners, minimal openings, and completely flush-mount surfaces prevent collection of dust and bacteria.
Schutzklassen: IP65, IP66, IP69K
Choosing the right protection class (IP rating) is crucial. Typical requirements are IP65 for dust-tightness and basic jet-water protection, IP66 for high-pressure resistance, and IP69K for high-temperature, high-pressure cleaning. For more on this subject, the All-in-One PC Industrial: The Ultimate Rugged Guide offers useful comparisons for selection and environment matching.
Kühlkonzepte: Passiv gekühlt und lüfterlos
A passiv gekühlter Reinraum-PC dispenses with traditional fans, instead utilizing heat-conductive housings and internal designs that dissipate heat silently. This not only avoids stirring up contaminants, but also reduces mechanical failure and inconvenience associated with fan-maintenance. Many leading Fanless Touch Panel PCs for Demanding Industries exemplify these principles.
Bedienung: Touchscreen und Hygienetastatur
Operation in cleanrooms necessitates carefully chosen input methods. Touchscreens for cleanrooms with robust, smooth surfaces allow for glove operation and easy disinfection. Where keyboards are necessary, Hygienetastatur Reinraum models are used—these are durable, washable, and fully sealed, preventing liquid ingress and making cleaning fast and simple.
Typische Einsatzbereiche und regulatorische Standards
Pharmaceutical and Biotech Production
Computers in pharmaceutical environments must comply with GMP and FDA requirements, ensuring they do not jeopardize product sterility or safety. Data collection, recipe management, and batch documentation are typical tasks handled by PCs under these strict conditions.
Food and Beverage Industry
In food processing, equipment must tolerate aggressive cleaning regimens, often requiring IP69K certification for protection against hot water jets and detergents. Stainless steel and smooth-surface construction ensure compliance with hygiene standards and regular disinfecting.
Medical Device Manufacturing
Cleanroom computers are pivotal for tracking production steps, managing digital records, and supporting traceability—a core regulatory requirement for medical devices. Sterility and robust build quality are non-negotiable here.
Semiconductor and Electronics Manufacturing
Even particle-sized contamination can destroy yields in silicon wafer and microchip fabrication. A Reinraum PC with absolute dust exclusion, chemical resistance, and no airflow emission is a must, with passive cooling and a fugenloses Design being essential for compliance.
For decision makers seeking proven, rugged IT platforms for process automation and data collection in such contexts, reviewing All-in-One PC Industrial: The Ultimate Rugged Guide can provide valuable purchasing guidance.
Fazit: Worauf bei der Auswahl zu achten ist
Selecting the best computer for a cleanroom means combining several critical criteria: maximize hygienic design (especially seamless, stainless construction), prioritize appropriate IP protection class (IP65/IP66/IP69K), and insist on passive, fanless cooling. Assess whether a PC-Einhausung offers sufficient benefit or if a dedicated Reinraum-Computer is justified given your application and contamination risk. Factor in necessary regulatory certifications such as GMP and FDA. Finally, always ensure that user interfaces—touchscreens or Hygienetastatur Reinraum—are compatible with the cleaning requirements and operator gloves typical for your site.
