Project d Air Handling Unit (AHU) Solution for RusXXXX
In March 2024, our team collaborated with RusXXXX, a leading European company specializing in HVAC systems, to optimize their Air Handling Units (AHUs) by integrating our high-efficiency EC Centrifugal Fans. The goal was to enhance the performance, energy efficiency, and operational reliability of their AHUs, which are critical components in ensuring optimal indoor air quality and temperature control.
Challenges
RusXXXX required a fan solution that could meet specific technical specifications while maintaining high energy efficiency. The key requirements were:
- ●Voltage: : 400
- ●Power Consumption: 2595W
- ●Airflow: 8661 m³/h
- ●Static Pressure: 2114 Pa
- ● Annual Demand:2000 units per year

Information
- Client: RusXXXX
- Location: Europe
- Date: March,2024
- Project : Air Handling Unit (AHU) Solution for RusXXXX
- Using product: EC Centrifugal Fan
- Model No: LWBE3G450-188PT-09
- Specifications requirements : 400V,2595W,8661m³/h,2114Pa
The challenge was to provide a fan model that not only met these stringent requirements but also offered long-term reliability and reduced energy consumption.
Solution
After a thorough analysis of RusXXXX’s needs, we recommended our LWBE3G450-188PT-09 EC Centrifugal Fan, which features a backward-curved plug fan design driven by an EC motor. This model was selected for its superior performance in demanding HVAC applications, where efficiency and durability are paramount.
Electrical Protection: Current limiting protection, Over-temperature protection, Over-current protection
Locked-rotor protection, Input power supply lacks phase protection
Soft Start:Delay time <35 seconds to full speed
VSP Control:Control signal VSP voltage range 1.5±0.1VDC~9.5±0.2VDC
Speed control system: Control input 0~10VDC(RS485 external control box can be connected
Key features of the solution included:
-
High Efficiency: The EC motor technology in the fan provides significant energy savings compared to traditional AC motors, ensuring lower operational costs for the client.
-
Optimized Airflow and Pressure: The fan’s design allows it to deliver the required 8661 m³/h airflow and 2114 Pa static pressure, ensuring the AHU operates at peak efficiency.
-
Scalability: With an annual demand of 2000 units, we ensured a reliable supply chain to meet RusXXXX’s production needs without any delays.
Results
The implementation of the LWBE3G450-188PT-09 fans in RusXXXX’s AHUs has resulted in:
-
Improved Energy Efficiency: The use of EC motor technology has reduced energy consumption by up to 30%, leading to significant cost savings for the client.
-
Enhanced System Reliability: The fans have contributed to the overall reliability of the AHUs, minimizing maintenance requirements and downtime.
-
Positive Environmental Impact: By reducing energy consumption, the solution has also contributed to lowering the carbon footprint of RusXXXX’s operations.
RusXXXX has expressed high satisfaction with the results and has committed to continuing our partnership, with plans to integrate our fans into more of their HVAC systems in the future.
