FAQ :
1,Q: How does DC power improve PUE in data centers compared to
traditional AC FFUs?
A: Our 48V DC system eliminates AC/DC conversion losses, reducing
power consumption by 18-22% per rack. Integrated with lithium-ion
UPS backups, it maintains airflow during grid fluctuations—critical
for Tier IV data centers requiring 99.995% uptime.
2,Q: Can the 110+35mm modular design adapt to legacy server racks?
A: Yes, the dual-height chassis allows:
35mm slim units for retrofitting existing 19" racks
110mm full-capacity units for new high-density deployments
Mixed configurations via tool-free magnetic coupling
3,Q: How does IoT integration prevent airflow disruptions in AI
server clusters?
A: Embedded sensors monitor:
Real-time server heat loads (via thermal imaging)
Particulate levels (0.3μm resolution)
Filter pressure drop (auto-alerts at 90% capacity)
The system dynamically redistributes airflow within ±2% variance,
preventing hot spots.
