R3G500-AP25-01: The RadiPac EC Powerhouse
The R3G500-AP25-01 is a high-efficiency 500mm centrifugal fan from ebm-papst’s acclaimed RadiPac series. Designed as a «Plug & Play» module for air handling units (AHUs), this fan features a backward-curved aluminum impeller directly driven by a 3-phase GreenTech EC motor. Unlike belt-driven systems, the R3G500-AP25-01 requires zero maintenance on transmission parts and eliminates hygiene risks associated with belt dust. It operates on a wide voltage range (3~ 380-480 VAC), making it a global standard for premium ventilation projects requiring high static pressure and low vibration.

- Impeller Material: Sheet aluminum (welded).
- Protection: IP54 (Electronics completely sealed).
Engineer’s Retrofit & BMS Guide
Lifecycle State: Active (High Performance). Diagnosis: The integrated electronics feature a status LED and an alarm relay. If the fan trips, check for «Phase Failure» or «DC Bus Overvoltage». The fan protects itself against overheating by derating performance rather than stopping immediately. Installation Advice: When installing in a FanGrid (multiple fans in parallel), use check valves to prevent backflow if one unit fails. Ensure the inlet cone (Inlet Ring) overlap is set to factory specs to maximize static pressure generation. Compatibility: Fully compatible with Siemens Desigo CC and TIA Portal via Modbus. Engineers can daisy-chain multiple fans and read individual RPM, power consumption (W), and motor temperature, allowing for precise PUE (Power Usage Effectiveness) calculations in data centers.
