Applications
Data Center Cooling Fans
In short: 6 series (33 models) cover 750–29,000 m³/h, up to 1550 Pa static pressure for Data Center Cooling Fans.
Data-center cooling has moved from room-level CRAC units to in-row, rack and direct-to-chip systems, and every step raises the pressure the fan must overcome. SUNXFAN supplies EC centrifugal blowers for coil-and-filter paths, rack-mount blowers for cabinets and 800 VDC axial fans for megawatt AI racks.

Typical applications
- CRAC and CRAH units needing 500–1000 Pa at constant airflow.
- In-row and rack-mounted cooling for 19-inch cabinets.
- 800 VDC direct-current cooling in megawatt AI racks.
- Free-cooling and indirect evaporative air handlers.
How to choose
Start from coil pressure drop and the redundancy scheme: N+1 units usually carry 60–70 % of total flow each, so size on the part-load curve rather than the free-air point.
Industry criteria, series picks and evidence
Cooling duty is continuous and redundancy-driven, so the fan is chosen on pressure at the operating point, controllability and service life — not on peak airflow alone.
| Criterion | Typical value | Why it drives the selection |
|---|---|---|
| Static pressure at duty | 300–700 Pa | Coil, filter and duct resistance in series |
| Airflow per module | 1,000–3,000 m³/h | Matched to the IT load and ΔT design |
| Control | 0-10V/PWM, Modbus RTU | Speed follows rack or return-air temperature |
| Duty cycle | 24/7, 8,760 h/yr | Bearing life and partial-load efficiency dominate |
