Main Application Scenarios
High-Density Server Rack Cooling
The R3G355-RJ91-02 is optimized for server rack cooling systems where high static pressure is required to maintain stable airflow through compact air channels and densely packed heat exchangers. Its EC motor technology helps reduce energy consumption in modern data center infrastructure.
Precision Air Conditioning for Telecom Rooms
This centrifugal EC fan is commonly integrated into telecom shelter cooling units and close-control air conditioners. The intelligent MODBUS communication allows seamless connection with building management systems (BMS) for remote monitoring and airflow adjustment.
Industrial Electronic Equipment Cooling
The R3G355-RJ91-02 is also used in industrial control cabinet ventilation, inverter cooling systems, and power electronics thermal management applications requiring stable long-term operation and smart EC fan control.
Frequently Asked QuestionsQ1: Why is the R3G355-RJ91-02 suitable for high static pressure HVAC systems?
This EC centrifugal fan delivers up to 1100 Pa static pressure, making it highly effective for precision cooling systems with restrictive airflow paths, dense evaporator coils, and long duct resistance commonly found in data center HVAC applications.
Q2: Does this fan support intelligent building management integration?
Yes. The R3G355-RJ91-02 supports RS-485 MODBUS-RTU communication, integrated PID control, alarm relay output, and 0-10V/PWM speed control, allowing easy integration into BMS and precision air conditioning control systems.
Q3: How can I troubleshoot an EC centrifugal fan showing undervoltage or phase failure alarms?
First inspect the 400V power supply stability and phase sequence. Then verify communication wiring, external control signals, and terminal connections. The built-in protection system may temporarily disable operation to protect the motor and electronics from abnormal voltage conditions.
