VLT® AQUA Drive 具有世界一流的成本效率

  • 我们在各个开发阶段都密切关注安装新一代 VLT® AQUA Drive 的净效率等能源效率,事实表明,与传统交流驱动解决方案相比,该变频器在第一年可以节省高达 25% 的投资成本。这相当于以 IE 3 级电机代替 IE 2 所节约的成本。

    选择新一代 VLT® AQUA Drive 的五个原因

    1. 节能设计 

    新一代 VLT AQUA Drive 的控制算法和设计主要用于减少热损耗、最大幅度提高能源效率。组件的负载绝不会超过其负载能力的 80%。这可以降低热损失并提高效率。

    2. 智能化的散热管理
    独特的背板冷却概念可将高达 90% 的热量传递到室外。这可以因不需要安装空调而节省大量能源。

    3. 自动适应应用
    约 90% 的电动机超负荷 10% 以上。在 90% 负载时 ,AEO 功能可节省约 2% 的能源,整个系列的效率提高 5% 。

    4. 节能谐波抑制
    我们独特的 VLT® Low Harmonic Drive 内置集成 AAF 滤波器,能源效率比采用有源前端技术的传统变频器高 1–2% 。低负载睡眠功能可确保进一步节省能源。

    5. 所有电动机最佳控制
    VLT® AQUA Drive 可有效应用于市场上各种电动机,您可自由选择电动机供应商。最新开发成果之一用于高速永磁电动机。独特的 VVC+ 控制技术非常适合配备PM 电动机的高速涡轮鼓风机,相比于使用传统变频器,可进一步节省 0.5 - 3% 的能源。

    节省安装成本、操作简便

    依托我们在市场上的首台专用供水和污水处理变频器的长期经验,新一代的 VLT AQUA Drive 提供非常高效的安装和调试解决方案,相比传统变频器,可节省 10-20% 的成本。

    选择新一代 VLT® AQUA Drive 的八个原因

    1. 节省配电盘空间
    当安装完整的系统时,Danfoss VLT® Low Harmonic Drive 内置集成 AAF 滤波器的独特组合、并排安装新一代的 VLT AQUA Drive 的紧凑式设计,使成套设备占用空间极小。

    2. 直接室外安装
    作为标准,Danfoss 提供防护等级为 IP66/NEMA 4X 的变频器。除了使变频器更贴近泵便于控制外,还可以降低电缆成本、消除对空调容量的需要和降低控制室成本。

    3. 标配长电缆配电能力
    VLT® AQUA Drive 无需额外组件即可使用最长 150 米的屏蔽电缆或最长 300 米的非屏蔽电缆提供无故障操作。

    4. 空调投资降低 90%
    空调系统散去变频器产生的热量,独特的 Danfoss 背板冷却系统可降低 90% 的空调系统投资。 

    5. 集成谐波抑制
    VLT AQUA Drive 还标配针对 40% 的 THDi 水平的集成谐波抑制解决方案。这不仅可以节省空间和成本,还可以使安装更简单。

    6. 标配印刷电路板保护
    从 90 kW 开始,VLT AQUA Drive 标配 3C3 PCB 涂层,以确保在恶劣的废水环境仍具有长使用寿命。

    7. 易于调试
    无论是 0.25 kW 或 2 MW 的变频器,您都会获得嵌入本地语言的控制面板、新的 SmartStart(智能启动)功能和其他许多节省时间的功能。

    8. 设计最低使用寿命为 10 年
    由于 VLT AQUA Drive 具有高质量组件、最高 80% 的组件负载和 PCB 降尘智能热管理,因此无需定期更换部件,如电解电容器和风扇。

    无可比拟的组合,适用于所用供水应用

    Danfoss Drives 率先推出仅用于水行业的专用变频器。我们凭着多年来积累的所有应用专门技术研制出具有许多优点的新一代 VLT AQUA Drive。

    VLT AQUA Drive 非常适合供水和污水处理应用。易用、灵活、可靠。专用软件功能适用于从调试到停机各种运行状况,有助于保护您的资产。这些功能包括:防止发生水锤作用,减少泵和鼓风机维护,比传统变频器控制节省更多能源。

    VLT AQUA Drive 在保持最低能耗和最低维护成本的同时,可以最大限度地延长旋转设备的使用寿命。
