With over three decades of engineering experience, we partner closely with clients to design and tailor computers precisely matched to their unique operational demands—whether in heavy industry, outdoor facilities, or medical applications. Each project is approached with a deep focus on robust hardware design, incorporating advanced filtering, reinforced casings, and industrial-grade sealing. We place a strong emphasis on in-depth testing, including comprehensive burn-in procedures, to guarantee functional reliability throughout the entire product lifecycle. Our commitment to manufacturer-neutral solutions and flexible production ensures that every system not only meets but exceeds expectations for resilience and performance in challenging environments.
What Are Waterproof Computers and Why Do You Need Them?
A waterproof computer, also known as a water-resistant or sealed PC, is an industrial-grade computing system engineered to prevent water ingress, dust penetration, and other environmental hazards. Devices, such as a waterproof PC cleanroom solution, are fundamental in sectors where regular electronics fail due to moisture, frequent washdown, or exposure to aggressive cleaning agents. Key industries include food processing, outdoor logistics, pharmaceutical production, chemical facilities, and heavy-duty manufacturing environments.
Typical Use Cases
- Food & beverage processing plants (require waterproof computers for strict hygiene regulations).
- Outdoor logistics hubs (exposed to rain, dust, and temperature fluctuations).
- Cleanrooms and pharmaceutical labs (where contamination prevention is critical).
- Vehicle-mounted workstations for construction or mining (challenging weather conditions).
Protection Classification: Understanding IP Ratings
The Ingress Protection (IP) rating classifies the encapsulation level against solid particles and liquids. Below is a comparison table of common industry standards used with waterproof computers:
| IP Level | Protection Description | Typical Application Example |
|---|---|---|
| IP65 Computer | Dust tight, protected against water jets | Factory floor panels, light washdown zones |
| IP67 Computer | Dust tight, immersion up to 1m | Outdoor PC IP67 for transport or agriculture |
| IP68 | Dust tight, long-term immersion | Heavy outdoor or marine systems, see industrial IP68 use cases |
| IP69K PC | Dust tight, high-temperature/high-pressure water jets | Food industry, high-pressure washdown (e.g. meat processing) |

Advantages of Waterproof PCs Compared to Standard Computers
- Enhanced Longevity: Their sealed enclosures, often made from stainless steel (SUS304/316), shield internal components from moisture, dust, and chemicals.
- Reduced Downtime: Less prone to failure due to liquid ingress, vital in production lines with tight uptime metrics.
- Hygiene Compliance: Smooth housings and waterproof designs simplify disinfection according to food and pharma requirements.
- Easy Maintenance: Fanless design prevents dust clogging, and M12 connectors further enhance liquid and dust resistance.
- Flexible Installation: Panel-PC and rackmount options allow wall, machinery, or workstation integration in demanding environments.
Compared to conventional computers, waterproof PCs meet MIL-STD ruggedness, are often NEMA 4X classified, and integrate advanced components such as Intel Core i5/i7/i9 CPUs and NVIDIA GPUs even in fanless, waterproof mini-PC formats.

How to Select the Right Waterproof Computer?
Step-by-Step Selection Guide (With Protection Rating Calculator)
- Assess Your Environment: Is your space exposed to dust, water jets, full immersion, or high-pressure cleaning?
- Determine Required IP Rating: Use the following guideline:
- IP65 computer: For dry, dusty, or light water exposure.
- IP67 computer: For immersive cleaning or outdoor exposure.
- IP69K PC: For full washdown, use of high-pressure cleaners.
- Decide on Form Factor: Panel-PC, rackmount, mini-PC, or custom enclosure? Stainless steel options are preferred for hygienic applications.
- Check Compatibility: Does the system support your operating system (e.g., Windows 11), RAID for data redundancy, or Edge-AI applications?
- Consider Maintenance & Cleaning: Prefer fanless, smooth chassis designs to reduce buildup and simplify washdown.
- Budget and Life Cycle: Analyze acquisition vs. total cost of ownership – including downtime, maintenance, and longevity.

Common Selection Mistakes to Avoid
- Over- or underestimating required IP protection (leading to unnecessary costs or hardware failures).
- Neglecting future-proof features such as support for modern CPUs (Intel 12th/13th/14th Gen) or AI integration.
- Choosing a standard, non-industrial enclosure in a wet or dusty zone.
Tips for Integration and Maintenance
Best Practices for Integration
- Plan wiring using waterproof connectors such as M12 or sealed cable glands; ensure all ports maintain IP rating when unused.
- Consider energy options, e.g. PoE+ (Power over Ethernet Plus) reduces wiring and installation time.
- Integrate with existing industrial networks seamlessly by ensuring protocol compatibility.
- Enable easy upgrades with modular or accessible designs, especially when AI acceleration (NVIDIA GPUs) or additional I/Os are needed.
Cleaning and Maintenance in Challenging Environments
- For food/pharma: Use non-abrasive, food-safe cleaning agents; suitable for high-pressure and high-temperature washdown (see IP69K).
- Perform regular inspection of seals, gaskets, and connectors for integrity.
- Fanless (fanless design) units require less frequent cleaning and minimize contamination risks.
- Train staff on proper cleaning techniques and check for NEMA 4X or similar certification for aggressive settings.
