Our commitment is to deliver solutions that not only meet but anticipate the unique and evolving requirements of our customers’ applications.


What is a Fanless Industrial PC?

A fanless industrial PC (Industrie-PC), also known as a passively cooled IPC or embedded PC, is a robust computing system specifically designed for industrial or harsh environments. Unlike conventional computers, these devices operate without active cooling components such as fans. Instead, they rely on passive cooling mechanisms, which distribute and dissipate heat efficiently through heatsinks and thermally optimized chassis designs. This makes them ideal for use in environments with requirements for dust, dirt, or noise reduction, as well as minimal maintenance.

Fanless industrial PCs are available in various forms, including Box-PCs for space-efficient installations, Panel-PCs with built-in displays for machine interfaces, and specialized embedded PCs for IoT and automation applications. These PCs typically run operating systems such as Windows or Linux and support a wide range of processors, including Intel Atom, AMD Ryzen, and ARM Cortex.

Advantages and Disadvantages of Fanless Systems

Key Benefits

  • Maintenance-free operation: No moving parts result in minimal wear and tear, substantially reducing maintenance efforts over the system’s lifecycle.
  • Robust and long-lasting: Fanless IPCs are extremely durable, offering high resistance to vibrations, shocks, dust, and moisture, even in demanding industrial or outdoor settings.
  • Noise reduction: The absence of fans means silent operation—an important feature in noise-sensitive environments, such as laboratories or cleanrooms. For more specifics on cleanroom requirements, read the Industrial PC for Cleanrooms: Selection & Demands guide.
  • Energy efficiency: Passively cooled embedded PCs typically consume less energy since there are no fans or additional cooling hardware drawing power.
  • Enhanced system protection: Optimized enclosures with high IP ratings such as IP65 help safeguard internal components from liquids and dust.

Potential Disadvantages

  • Limited peak performance: Thermal management through passive cooling can place a cap on the maximum attainable processor performance, compared to actively cooled systems.
  • Specific installation requirements: Heat must be dissipated efficiently, so installation space and mounting technique can affect cooling capabilities.
  • Cost: High-quality, industrial-grade fanless computers may command a higher initial investment, justified by lower total cost of ownership.

Typical Application Areas in Industry

Fanless industrial PCs are integral to modern industrial automation and digitalization. Here are some important use cases:

  • Automation & Manufacturing: Embedded PCs are central to PLC control, robotics, and process management.
  • Industrial IoT (IIoT) and Edge Computing: An IoT Edge Computer for industrial environments enables real-time data processing at the source, reducing latency and bandwidth requirements.
  • Factory and machine interfaces: Fanless Panel-PCs with touchscreens are widely used as mobile workstations in industrial environments for system monitoring and control.
  • Harsh and heavy-duty environments: Rugged IPCs with IP65 protection and excellent shock/vibration resistance thrive in dusty, wet, or high-vibration locations such as warehouses or transport hubs.
  • Cleanroom and food industry: Fanless designs eliminate the risk of contamination from moving parts, supporting compliance with stringent hygiene standards.
  • Test and measurement systems: Embedded PCs act as data loggers or process controllers in sensor networks and laboratory setups.

Technical Features and Selection Criteria

Key Technical Features

  • Passive Cooling: High-performance heat sinks and thermal designs for continuous, reliable operation.
  • Protection Ratings: Enclosures certified to IP65 or even IP67 guard against dust and water ingress.
  • Shock and Vibration Resistance: Mechanically reinforced builds with compliance to industry standards (shock/vibration resistance) protect against environmental hazards.
  • Long Lifecycle and Availability: Ruggedized components and long-term availability support industrial deployment cycles.
  • Flexible Interfaces: Rich connectivity options, including USB, serial ports (RS232/422/485), CAN, GPIO, Ethernet (1-10 Gbit), and optional wireless (Wi-Fi, LTE, 5G) connections.
  • Wide Power Input Ranges: Voltage tolerance (e.g., 9–36 VDC), important for fluctuating industrial power supplies.
  • Processor Diversity: Availability of Intel Atom, AMD Ryzen, and ARM Cortex options for tailored performance, energy efficiency, or specialized AI/Edge workloads.

How to Select the Right System

The right choice of a lüfterloser Industrie-PC depends on a thorough analysis of operational demands and environmental parameters. Key selection criteria include:

  • Required computational performance and memory
  • Harshness of the operating environment (e.g., dust, humidity, temperature extremes)
  • Protection class (IP65, IP67)
  • Mounting and space requirements: Compact Box-PC vs. integrated Panel-PC
  • System compatibility (Windows, Linux, real-time OS, Azure IoT integration)
  • Expansion options and I/O ports for your application’s connectivity needs

For guidance on selecting systems for highly controlled environments, see Industrial PC for Cleanrooms.

Comparison: Passive vs. Active Cooling

Attribute Passive Cooling (Fanless) Active Cooling (With Fans)
Maintenance Virtually maintenance-free; no fans to replace or clean Requires regular cleaning and fan replacement
Noise Level Completely silent (>0 dB) Noticeable fan noise
Dust/Contaminant Resistance Sealed, extremely resistant (suitable for IP65/IP67 enclosures) Vulnerable to dust ingress, can lead to failures
Operational Lifetime Long, since there are no moving parts Reduced due to mechanical wear of fans
Thermal Performance Ceiling Limited by passive heat dissipation Higher cooling possible for performance-intensive CPUs/GPUs
Suitability Ideal for harsh, dusty, sensitive, or low-maintenance environments Best for high-performance applications in controlled environments

Important Protection Classes and Certifications

When choosing a fanless industrial PC, protection ratings such as IP65 or IP67 are key indicators of system resilience. These certifications specify the level of protection against dust and liquids:

  • IP65: Complete dust protection and protection against low-pressure water jets from any angle.
  • IP67: Complete dust protection and protection against immersion in water up to 1 meter deep for up to 30 minutes.

Additionally, certifications for shock and vibration resistance ensure reliable use in transport, production, or mobile installations. For mobile industry environments and safety considerations, read about Mobile Rack Systems Industrial: Space, Efficiency, Safety.
