Description

Introduction to Elevator Inverter Cooling Fan FFB0824SHE
Manufactured by NANJING ZHUYE ELEVATOR PARTS

The FFB0824SHE is a high-performance DC axial fan engineered specifically for cooling elevator inverters and drive modules. Designed, tested, and mass-produced by NANJING ZHUYE ELEVATOR PARTS, it guarantees stable thermal management for variable-frequency drives (VFDs) ranging from 3 kW to 75 kW. The fan is CE, UL, and RoHS certified and has been field-proven in OTIS, KONE, Schindler, Mitsubishi, and Thyssen systems worldwide.

1. Technical Specifications
• Frame Size: 80 mm × 80 mm × 25 mm (3.15″ × 3.15″ × 0.98″)
• Bearing System: Dual ball bearings, 70 000 h L10 life at 40 °C
• Rated Voltage / Current: 24 V DC ± 10 %, 0.28 A (max)
• Airflow: 42 CFM (1.19 m³/min) at 6 800 RPM
• Static Pressure: 9.4 mm-H₂O (0.37 in-H₂O)
• Noise Level: 46 dB(A) at 1 m (typical)
• Operating Temperature: –20 °C to +75 °C, 95 % RH non-condensing
• Connector: 2-pin Molex 2510 or 3-pin TACH/PWM on request
• Ingress Protection: IP55 impregnated PCB for dust and moisture resistance

2. Advanced Features
• PWM Speed Control: 0–100 % duty cycle for energy-saving operation; reduces noise and power consumption during low-load conditions.
• Tachometer Output: Real-time RPM feedback to the elevator controller, enabling predictive maintenance and immediate fault alerts.
• Balanced Impeller: Dynamically balanced PBT blades reduce vibration, extending inverter capacitor life.
• Locked-Rotor & Reverse-Polarity Protection: Automatic restart prevents motor burnout and safeguards drive circuitry.
• EMI Shielding: Integrated ferrite ring minimizes electromagnetic interference with encoder and communication cables.

3. Energy Efficiency & Sustainability
NANJING ZHUYE ELEVATOR PARTS optimizes every fan for maximum aerodynamic efficiency. The FFB0824SHE consumes only 6.7 W at full speed, contributing to overall lift energy savings certified by TÜV. All plastics are halogen-free and fully recyclable, supporting green-building initiatives.

4. Installation & Compatibility
• Drop-in replacement for 80 mm square inverter fans across 24 V DC systems.
• Pre-drilled 71.5 mm pitch holes match OTIS 5060, KONE EcoDisc, and Schindler 5500 series.
• Optional finger-guard and rubber grommet kits reduce installation time to under three minutes.

5. Rigorous Testing & Reliability
Each unit undergoes 100 % burn-in for 4 hours at 75 °C, salt-fog spray for 48 h, and vibration tests at 5 g RMS to simulate elevator shaft conditions. MTBF exceeds 200 000 h per MIL-HDBK-217F.

6. Applications
Ideal for cooling:
• Elevator VFDs, servo drives, regenerative modules
• Machine-room-less (MRL) controllers with restricted airflow
• High-speed traction elevators (>4 m/s) generating elevated heat loads

7. After-Sales Support
NANJING ZHUYE ELEVATOR PARTS offers a 3-year warranty, 24-hour technical hotline, and global next-day spares availability. Custom cable lengths, PWM controllers, and thermal-sensor integration are available on request.

8. Conclusion
By selecting the FFB0824SHE from NANJING ZHUYE ELEVATOR PARTS, specifiers gain a quiet, energy-efficient, and ultra-reliable cooling solution that extends inverter life and maximises passenger safety.
