ebm-papst推出两款大直径轴流风机，用于数据中心冷却与散热设备

Industrial cooling systems in data centers, commercial refrigeration plants, and process facilities require high volumetric airflow while meeting increasingly stringent acoustic limits and energy conservation mandates. To address these operational constraints, ebm-papst introduced two large-diameter axial fan systems, the 1030 mm AxiBlade.S.Perform and the 1250 mm AxiBlade.S, engineered specifically for air-cooled chillers, condensers, recoolers, and heat dissipation equipment.数据中心、商用制冷装置和工艺设施中的工业冷却系统需要高体积风量，同时还要满足日益严格的噪声限值和节能要求。为应对这些运行约束，ebm-papst 推出了两款大直径轴流风机系统——1030 mm AxiBlade.S.Perform 和 1250 mm AxiBlade.S，专为风冷式冷水机组、冷凝器、再冷却器和散热设备而设计。

Modular Aerodynamic Design and Blade Geometry
Airflow performance in heat rejection equipment depends heavily on balancing system pressure drop against fan acoustics. Rather than treating the fan impeller as an isolated component, the expanded product architecture coordinates the aerodynamic interaction between the impeller blades, nozzle shroud, drive motor, and control electronics.模块化空气动力学设计与叶片几何结构
散热设备中的风量性能在很大程度上取决于系统压降与风机声学特性之间的平衡。该扩展产品架构并未将风机叶轮视为孤立部件，而是协调叶轮叶片、喷嘴导风圈、驱动电机和控制电子元件之间的空气动力学相互作用。

The 1030 mm AxiBlade.S.Perform utilizes an individual blade mounting architecture. Composite aerodynamic blades attach directly to a central hub ring and can be configured at the factory across multiple blade pitch angles. This modular pitch adjustment permits precise aerodynamic adaptation to specific system resistance curves. The unit generates volumetric flow rates up to 50,000 m³/h under free-blowing conditions and delivers 32,000 m³/h at a backpressure of 330 Pa. It is housed in a composite wall ring optimized for structural damping and installation versatility.1030 mm AxiBlade.S.Perform 采用独立叶片安装架构。复合空气动力学叶片直接安装在中央轮毂环上，并可在工厂按多种叶片安装角进行配置。这种模块化安装角调节功能可精确适配特定系统阻力曲线的空气动力学要求。该机组在自由送风工况下可产生高达 50,000 m³/h 的体积流量，并在 330 Pa 背压下输送 32,000 m³/h 的风量。风机安装在经过结构阻尼和安装灵活性优化的复合材料壁环中。

Acoustic Mitigation and Extended Volumetric Capacity
For installations requiring maximum airflow with reduced acoustic emissions, the 1250 mm AxiBlade.S scales the modular blade concept to larger surface-area heat exchangers. Its large impeller diameter allows the fan to move up to 58,000 m³/h in free-blowing operation and 41,000 m³/h against 150 Pa static pressure at lower rotational tip speeds, mitigating aerodynamic turbulence noise. The unit incorporates a sheet-metal wall ring paired with an integrated protective guard grill, making it suited for large industrial chillers, fluid coolers, agricultural facilities, and electrical transformer cooling stations.降噪措施与扩展风量容量
对于需要最大风量并降低噪声排放的安装场合，1250 mm AxiBlade.S 将模块化叶片概念扩展应用于更大表面积的换热器。其大直径叶轮使风机能够以较低的旋转叶尖速度运行，在自由送风工况下输送高达 58,000 m³/h 的风量，并在 150 Pa 静压下输送 41,000 m³/h 的风量，从而减轻空气动力湍流噪声。该机组采用金属板壁环并配有一体式防护网罩，适用于大型工业冷水机组、流体冷却器、农业设施以及电力变压器冷却站。

Drive Architecture and Digital Ecosystem Connectivity
Both fan models are powered by electronically commutated (EC) external rotor motors delivering output ratings up to 8 kW. The motor electronics operate across an ambient temperature envelope from −40 °C to +70 °C and can be configured with either passive or active power factor correction (PFC) to reduce harmonic line distortions in power distribution networks.驱动架构与数字生态系统连接
两款风机型号均由电子换向（EC）外转子电机驱动，输出功率额定值最高可达 8 kW。电机电子元件可在 −40 °C 至 +70 °C 的环境温度范围内运行，并可配置无源或有源功率因数校正（PFC），以减少配电网络中的谐波线路畸变。

Digital communication is integrated via a standard MODBUS-RTU interface, linking the fans directly into the ebm-papst NEXAIRA digital ecosystem. This bus connectivity transmits continuous operating parameters including speed, power consumption, thermal load, and vibration metrics. System integrators and facility operators can utilize this telemetry for closed-loop demand control, remote diagnostics, and condition-based predictive maintenance.数字通信通过标准 MODBUS-RTU 接口集成，将风机直接接入 ebm-papst NEXAIRA 数字生态系统。该总线连接可传输包括转速、功耗、热负荷和振动指标在内的连续运行参数。系统集成商和设施运营方可利用这些遥测数据实现闭环需求控制、远程诊断和基于状态的预测性维护。

Compliance and Industry Showcase
The fan systems satisfy the efficiency thresholds established by the European Ecodesign Directive and the upcoming European Fan Regulation (ErP 2026), providing original equipment manufacturers (OEMs) with certified performance data for regulatory compliance. The product line was presented to industrial engineers at the Chillventa trade exhibition in Nuremberg, Germany.合规与行业展示

The regulatory framework governing industrial ventilation in Europe is undergoing a major transition under Commission Regulation (EU) 2024/1834, commonly designated as ErP 2026, which repeals Regulation (EU) 327/2011. Commencing July 2026, this regulation enforces stricter minimum energy efficiency thresholds across industrial fans spanning 125 W to 500 kW, while mandating wire-to-air measurement procedures that evaluate motor, drive electronics, and aerodynamics as an integrated system rather than testing the bare fan shaft.欧洲工业通风领域的监管框架正在根据欧盟委员会条例 (EU) 2024/1834（通常称为 ErP 2026）经历重大转型，该条例废止了原条例 (EU) 327/2011。自2026年7月起，该法规将对功率范围在 125 W 至 500 kW 之间的工业风机实施更严格的最低能效限值，同时强制要求采用“线到风”（wire-to-air）测量程序，将电机、驱动电子元件和空气动力学性能作为一个集成系统进行评估，而不是仅测试裸露的风机轴。

Within the 1000 mm to 1250 mm diameter class, conventional industrial heat rejection equipment historically employed standard AC asynchronous induction motors paired with belt-drive pulleys or external variable frequency drives (VFDs). Belt drives incur parasitic mechanical transmission losses between 2% and 5% and require routine maintenance, whereas integrated brushless DC/EC permanent magnet motors achieve electrical efficiency levels equivalent to IE5 standards across wide modulation ranges.在 1000 mm 至 1250 mm 直径级别中，传统工业散热设备历来采用标准交流异步感应电机，搭配皮带传动轮或外部变频驱动器（VFD）。皮带传动会产生 2% 至 5% 的寄生机械传动损耗，并且需要定期维护；而集成式无刷直流/EC 永磁电机则可在宽泛的调节范围内达到相当于 IE5 标准的电气效率水平。

In competitive comparisons, modular axial fans in this scale — such as the Ziehl-Abegg ZAplus and FE2owlet series — also target noise reduction through bionic blade designs and integrated diffusers. The engineering advantage of modular blade-angle configuration, as utilized in the AxiBlade architecture, lies in optimizing fan static efficiency (wire-to-air) precisely at the design operating point without requiring aerodynamic throttling or over-sizing drive motors, thereby mitigating broadband vortex shedding and reducing low-frequency blade-pass noise in noise-sensitive urban installations.在竞品比较中，该尺寸级别的模块化轴流风机——例如 Ziehl-Abegg 的 ZAplus 和 FE2owlet 系列——同样通过仿生叶片设计和集成扩压器来实现降噪目标。AxiBlade 架构所采用的模块化叶片角度配置在工程上的优势在于：能够在设计工况点精确优化风机静效率（线到风），而无需进行空气动力学节流或过度放大驱动电机的规格，从而减弱宽带涡流脱落，并降低对噪声敏感的城市安装环境中的低频叶片通过噪声。
