Waterproof Mini PC - Intel Core Ultra
• Waterproof Fanless Edge Systems • Model: FM-15M-IP66
The FM-15M-66 is a compact, fully sealed IP66 mini PC on Intel Core Ultra. No fan, no vents, nothing to clog or wear out. Engineered to keep running where standard kit gives up.
✓ IP66 sealed ✓ Fanless, no moving parts ✓ Designed & built in Britain
OVERVIEW
Sealed to IP66. Built for outdoors.
Our waterproof fanless mini PC is equipped with the latest Intel Core Ultra processors, delivering performance in a compact, durable form factor sealed to IP66.
Designed for outdoor and extreme environments, the robust construction adapts to the harshest operating conditions. Whether exposed to dust, water, or wide temperature ranges in an industrial context or fully outdoors. The fanless design ensures quieter, longer-lasting performance with no moving parts.

WHY FANLESS AND RUGGED
Every design choice removes a reason to fail.
This isn't a standard mini PC with a tougher case. It's built from the environment inwards each decision aimed at one outcome, to keeps running, and reduce failures.

Fanless, sealed chassis
WHAT IT MEANS FOR YOU > No fan means no moving part to wear out and no vent to pull in dust or water. The most common cause of outdoor-PC failure simply isn't present so the maintenance visits it would have generated never happen.

IP66 sealing & sealed power entry
WHAT IT MEANS FOR YOU > The unit can sit fully outdoors rain, spray, wash-down without a protective cabinet. The power cable enters through a sealed connector, so the weakest point on most outdoor kit isn't a weak point here.

Intel Core Ultra performance
WHAT IT MEANS FOR YOU > Ruggedness usually means dated, underpowered silicon. Here it doesn't, you get current-generation Intel performance in the sealed chassis, configured to your workload so you're not paying for capability you won't use.

Wireless & mobile connectivity
WHAT IT MEANS FOR YOU > It can report from sites with no fixed network over Wi-Fi or a mobile SIM so you can deploy where cabling doesn't reach, and keep eyes on the unit remotely instead of driving out to check it.

Compact, Made in Britain
WHAT IT MEANS FOR YOU > It fits the enclosures, poles and cabinets the bigger systems can't and it's designed and milled in-house in Britain

TOTAL COST OF OWNERSHIP
The cheaper system is rarely the cheaper decision.
Purchase price is one line in the total. For kit deployed outdoors and at distance, the cost that matters is what it takes to keep it running over its life and that's where a sealed, fanless unit changes the maths.
STANDARD / VENTED PC OUTDOORS
⨂ Lower sticker price with a fan and vents that invite dust and moisture in.
⨂ Often needs a protective cabinet added cost, space and another thing to maintain.
⨂ Maintenance visits to clean or clear fans and filters.
⨂ Failure-driven truck rolls and replacements across a shorter life.
WATERPROOF MINI INTEL
✓ Sealed and fanless, the dust-and-moisture failure mode is removed by design.
✓ No cabinet required, it is its own enclosure is rated IP66.
✓ No fans, filters or vents to service.
✓ Fewer failures means fewer site visits the saving lands across the deployment's life.
WHERE IT FITS
Built for the environments others avoid.
Industrial
IP66 sealing withstands high-pressure water jets suited to food production, processing plants, and areas requiring regular wash-down.
Outdoor Infrastructure
Signal cabinets, roadside enclosures and trackside points where space is tight and exposure is constant.
Extreme Environments
Fanless, sealed operation from −10°C to 60°C ideal for exposed, dusty or wet locations where conventional systems fail.
FREQUENTLY ASKED QUESTIONS.
Questions about the Waterproof Mini Intel
Yes. Processor, memory and storage are configurable within the Core Ultra range, so the build can be matched to the application rather than over- or under-specified. Share your requirement and we will propose a configuration.
Power is delivered through the sealed IP68 Buccaneer connector, keeping the cable entry as weatherproof as the chassis. Mounting options depend on the site enclosure, pole or surface and we can advise on the right arrangement for your deployment.
Choose the Intel Mini when footprint and current-generation Intel performance are the priorities for a single-display or headless role. Choose the AMD Mini when you need to drive multiple high-resolution displays from one unit.
Lead time varies by configuration and current build schedule, and units are supplied with a standard 3 year warranty. Contact us for the current lead time and warranty terms for your specific build.
