K3G355-PH23-01: The Future of Industrial Ventilation
The K3G355-PH23-01 is a high-performance 355mm centrifugal fan module powered by ebm-papst’s cutting-edge GreenTech EC technology. Unlike traditional AC fans, this unit utilizes an electronically commutated motor that runs on a 3-phase mains supply (380-480 VAC), offering efficiency levels that far exceed ErP regulations. It features the RadiCal impeller, a hybrid glass-fiber reinforced composite design that optimizes airflow aerodynamics, significantly reducing turbulence and noise. This fan is the gold standard for data center cooling units, precision air conditioning, and clean room technology where precise control and energy savings are paramount.
Technical Specifications (EC)
- Impeller Diameter: 355 mm.
- Motor Technology: EC (Electronically Commutated).
- Voltage: 3~ 380-480 VAC (50/60 Hz).
- Control: 0-10V / PWM / Modbus-RTU.
- Protection: IP54 (Electronics completely sealed).
- Features: Soft start, thermal overload protection, locked-rotor protection.
Integration & BMS Compatibility
Lifecycle State: Active (Premium). Diagnosis: The integrated electronics provide advanced diagnostics. A status relay indicates faults (e.g., over-temperature, phase failure). If the fan stops, verify the 0-10V control signal and the DC supply to the interface (if external). Installation Advice: Requires no VFD. The speed control is built-in. Connect L1, L2, L3 and the control wires. Compatibility: Fully compatible with Siemens Desigo CC or TIA Portal via Modbus. Engineers can read real-time RPM, power consumption, and motor temperature directly on the SCADA system, enabling predictive maintenance strategies.

Why upgrade to EC?
Replacing a standard AC fan with the K3G355 can reduce power consumption by up to 50% at partial loads, offering a ROI of less than 12 months in 24/7 applications.
