Frequently Asked Questions

Can this fanless industrial PC run continuously 24/7 in high-temperature environments?

Yes. Featuring a 100% heavy-duty aluminum alloy passive cooling chassis and zero moving fans, the HYSTOU K4 operates reliably in extreme temperatures ranging from -20°C to 60°C (-4°F to 140°F). The fanless design prevents dust and particulate buildup, ensuring uninterrupted 24/7 performance in harsh factory environments.

Yes, the K4 supports Hardware Auto Power On (BIOS/Jumper setting), Wake-on-LAN (WoL), Scheduled Power On, and PXE boot. This ensures 24/7 automated boot-up for unattended kiosks, outdoor cabinets, and remote industrial sites without manual intervention.

Built with a solid-state fanless design (zero moving parts) and a thick aluminum-magnesium alloy casing, the K4 offers superior anti-vibration performance compared to traditional active-cooled PCs. The fully shielded metal chassis also minimizes EMI impact on sensitive industrial electronics nearby.

We offer a 3-Year Worry-Free Warranty and lifetime dedicated 24/7 technical support. All industrial PCs undergo rigorous 48-hour burn-in and wide-temperature stability testing before shipment to guarantee maximum reliability.

Yes. We offer flexible OEM/ODM services for bulk orders, including custom BIOS settings (such as Auto Power On or Wake on LAN), customized RAM/SSD capacities, custom logo printing, and specialized packaging.

The K4 fully complies with international quality and safety standards, holding CE, FCC, and RoHS certifications. Detailed compliance certificates and test reports are available upon request for regulatory filings or tender bidding.
