随着人工智能和高密度计算推动向液冷的强制性转变，CoolTrain 取代了缓慢、高风险的现场组装，采用即插即用解决方案，保证质量，加快项目进度，并从一开始就优化系统性能。
丹佛斯自豪地宣布推出丹佛斯 CoolTrain，这是一款模块化的预制和工厂测试的阀系子系统，旨在解决直接芯片液冷中能源效率和部署风险的关键挑战。
随着人工智能和高密度计算推动向液冷的强制性转变，CoolTrain 取代了缓慢、高风险的现场组装，采用即插即用解决方案，保证质量，加快项目进度，并从一开始就优化系统性能。
传统的现场液冷系统组装是造成效率低下的主要原因。手动组装的系统通常无法实现动态水力平衡，导致水泵过度运转，造成持续且大量的能源浪费。此外，这种方法速度慢、容易出错，并且存在泄漏和污染的风险，从而危及数据中心的正常运行。
“我们看到了客户面临的巨大压力。他们需要快速、大规模地部署液冷系统，但传统方法却因风险和低效而阻碍了他们的进展。CoolTrain 正是我们针对这一问题推出的解决方案。它以工厂保证的确定性取代了现场的各种不确定因素。我们希望帮助工程师们采用智能流程，并确保他们的系统从连接之日起就高效且防泄漏。

Danfoss Unveils CoolTrain to Accelerate Deployment of Liquid Cooling Systems

As AI and high-density computing drive the mandatory shift to liquid cooling, the CoolTrain replaces slow, high-risk, on-site assembly with a plug-and-play solution that guarantees quality, accelerates project timelines, and optimizes system performance from day one.
Danfoss is proud to announce the launch of the Danfoss CoolTrain, a modular pre-engineered and factory-tested valve train subsystem designed to address the critical challenges of energy efficiency and deployment risk in direct-to-chip liquid cooling.
As AI and high-density computing drive the mandatory shift to liquid cooling, the CoolTrain replaces slow, high-risk, on-site assembly with a plug-and-play solution that guarantees quality, accelerates project timelines, and optimizes system performance from day one.
The traditional on-site assembly of liquid cooling systems is a primary source of inefficiency. Manually assembled systems are often not dynamically hydronic balanced, leading to significant and constant energy waste from pumps working harder than necessary. Furthermore, this method is slow, prone to errors, and introduces risks of leaks and contamination, which can jeopardize data center operations.
“We saw the immense pressure our customers are under. They need to deploy liquid cooling fast and at scale, but the traditional methods are holding them back with risks and inefficiency. The CoolTrain is our direct answer to this. It’s about replacing on-site variables with factory-guaranteed certainty. We want to empower engineers to go with the smart flow, confident that their system is efficient and leak-proof from the moment it’s connected.”
– Moath Shanaah, Data Center Business Development Manager at Danfoss – Türkiye, Middle East and Africa
The Danfoss CoolTrain is a modular, custom-engineered subsystem that creates a seamless bridge between the facility’s main TCS cooling loops and the server racks. By moving the assembly process into a controlled factory environment, each unit is delivered to the site already pressure-tested, internally cleaned to certified ISO standards, pre-filled with coolant and hermetically sealed. This “sealed-for-site” approach reduces installation time from hours per rack to mere minutes and eliminates the primary cause of cooling system failures.
Core Innovations and Technical Benefits:
The CoolTrain integrates a number of Danfoss’s market-leading technologies into one solution to deliver measurable performance gains:
Engineered for Reliability: Established with market-leading FD83 interlockable coupling and highly flexible EHW194 Boston hoses to minimize the risk of leakage. The valve materials in contact with coolant are corrosion-resistant and have passed rigorous compatibility test for safe, long-term operation.
Smart Dynamic Balancing: At its core, the integrated AB-QM Pressure Independent Control Valve (PICV) provides automatic and continuous hydronic balancing. It constantly optimizes coolant flow to match the specific needs of each rack, ensuring maximum energy efficiency with optimized Power Usage Effectiveness (PUE) and an improved Water Usage Effectiveness (WUE).
Digital Intelligence and Control: When equipped with the optional NovoCon S digital actuator, the CoolTrain becomes a smart data source in the DCIM. It provides live telemetry on flow rates and temperatures, enabling remote optimization to match actual IT loads and facilitating predictive maintenance schedules to maximize uptime.
Danfoss CoolTrain Technical Specifications Overview:
