The Facility Distribution Unit (FDU) is a 5-megawatt liquid cooling system, engineered to serve entire data halls. It is now operational in AI data centers

WARSAW, MASOVIAN, POLAND, January 16, 2026 /EINPresswire.com/ — The rapid advancement of generative artificial intelligence has triggered a global technological arms race. Next-generation AI models not only learn faster and process increasingly large datasets, but most critically, demand unprecedented levels of compute power. This shift is placing immense pressure on data centers, accelerating the adoption of liquid cooling solutions and transforming the design of AI infrastructure to support high-density computing at scale.
This shift is accompanied by a sharp increase in power density – not incremental, but exponential. In modern AI clusters, 60-120 kW per server rack has become the new standard, with early deployments already exceeding 200 kW per rack. According to the latest hardware vendor roadmaps, by 2027, single rack deployments may require up to 600 kW of cooling capacity.

In this context, traditional liquid cooling systems based on distributed, in-row Coolant Distribution Units (CDUs) are reaching their limits. Each in-row CDU module typically serves a small group of racks, requires white space floor allocation, demands independent maintenance, and adds significant installation and operational overhead. When scaled to support tens of megawatts of IT load, this architecture becomes inefficient, costly, and increasingly difficult to maintain.
To address these challenges, we propose a new cooling topology – centralized, resilient, and purpose-built for the needs of large-scale AI deployments. The Facility Distribution Unit (FDU) is a 5-megawatt liquid cooling system installed outside the white space, engineered to serve entire data halls. It replaces dozens of scattered CDUs, simplifies cooling infrastructure, and significantly reduces the risk of failure near mission-critical IT hardware. It is now operational in AI data centers located in France and the East Coast of the United States.

What is a Facility Distribution Unit?
Facility Distribution Unit (FDU) is a centralized coolant distribution unit used in direct liquid cooling systems for large-scale server clusters, including GPU-intensive environments. Unlike traditional Coolant Distribution Units (CDUs), which are typically installed locally in IT rows, the FDU is deployed outside the white space – either in a technical corridor or even outside. This relocation fundamentally changes both the cooling architecture and the physical design of data centers.

The new cooling topology based on FDU eliminates the legacy model of numerous distributed small cooling loops (each with its own CDU, pump, and heat exchanger) and replaces them with a single, high-capacity unit supporting the entire IT zone through centralized supply and return loops. This significantly reduces the number of critical components placed directly near the IT hardware.

With high-pump head capabilities (loop reach exceeding 50 m), FDUs allow flexible placement of high-density racks based on power availability, structural constraints, or cabling, rather than proximity to cooling units. The use of standardized loop topology ensures repeatability across deployments: whether the system supports 20 or 200 racks, the piping layout, controls, and integration logic remain consistent. This reduces engineering effort, commissioning time, and the likelihood of configuration errors.

From a logical architecture standpoint, the FDU becomes the central node of the thermal cooling system, bridging the chilled water source with the downstream distribution network that feeds manifolds and server-side cold plates. As a result, local CDUs become obsolete – their function is taken over by a centralized FDU offering greater capacity, longer reach, and full diagnostic control via the facility management layer.

Key technical features of the 5 MW FDU unit:
1) Designed for full data halls and large-scale AI deployments:The 5 MW FDU provides the highest heat transfer capacity per unit available on the market, eliminating the need for dozens of in-row CDUs in high-density deployments.

2) Supports up to 60 AI racks at 80 kW each: Capable of supporting to 60 AI racks, each consuming around 80 kW and equipped with NVIDIA H100 GPUs or equivalent, enabling seamless operation of over 1,000 servers.

3) Compact footprint with high output capacity: At just 3.0 m (L) × 1.5 m (W) × 2.3 m (H), the unit delivers unmatched capacity per square meter, ideal for space-constrained facilities.

4) Smart 37 kW inverter system with predictive diagnostics: Embedded accelerometers, pressure and incline sensors feed a remote analytics platform. It enables early detection of operational anomalies, such as: dirty filters, sand fouling and debris buildup, pump wear or impeller damage, rising system friction or degraded hydraulic performance.

4) High pump head and multi-pump redundancy (N+1):Equipped with four industrial-grade pumps, each capable of 8,000 L/min, with peak burst performance up to 10,666 L/min. The unit includes multiple built in pumps that delivers twice the power of standard high-capacity CDUs, along with N+1 redundancy pumps. This makes it perfectly suited for large-scale secondary loop configurations that require high reliability.

5) Redundant electronic control panel with LCD HMI: Dual-path logic with redundant PLC controllers ensures full local control and immediate system response in case of alerts or anomalies. The intuitive, crystal-clear HMI interface gives operators real-time visibility and 24/7 operational control.
Integrated coolant conditioning system: Maintains coolant purity without the performance penalties associated with glycol-based fluids such as PG25, which can cause up to a 20% efficiency loss.

6) Customizable heat exchanger: The FDU contains a single, high-capacity heat exchanger that can be resized by removing or adding plates to match project-specific requirements.

7) Full compliance with Tier 3 Uptime Institute requirements: FDUs provide higher fault tolerance compared to legacy systems. With an N+1 redundant configuration: additional pumps and components – they continue operation during maintenance or a single-point failure. Centralized monitoring and onboard sensors also enable proactive diagnostics before issues impact IT hardware.

8) Future-proof scalability: Computing power demand from next-gen AI workloads is inherently unpredictable – models evolve faster than infrastructure investment cycles. FDU based cooling offers an adaptive, scalable architecture capable of supporting rapid increases in rack power density without requiring complete redesigns.

Introducing an Ambient Care Experience Integrated into Daily Life

LAS VEGAS, NV, UNITED STATES, January 16, 2026 /EINPresswire.com/ — Korea Lighting (CEO Dongwoo Lee) announced that it unveiled Neurélux, a light therapy–based brain health management solution, at CES 2026, the world’s largest IT and consumer electronics exhibition, which opened on January 6 (local time) in Las Vegas.

Korea Lighting is a technology company specializing in functional light semiconductor platforms. Built on its proprietary HS FRAME technology, which integrates LED chips, circuits, and heat dissipation structures into a single system, the company has developed high-value-added lighting solutions that precisely control wavelength and energy output. This technological foundation has enabled Korea Lighting to establish competitiveness across beauty, wellness, and healthcare applications while pursuing global market expansion.

HS FRAME technology supports compact product design while maintaining stable, high-output wavelengths, making it particularly suitable for medical and healthcare use. Leveraging this capability, Korea Lighting continues to advance its core semiconductor platform and broaden the scope of functional lighting applications.

At CES 2026, the company introduced Neurélux under the concept of “Ambient Brain Healthcare.” Neurélux is a non-invasive light therapy solution designed to support brain health management within everyday living spaces rather than clinical environments. Its core functionality is based on a dual-infrared structure that enables continuous, stable light delivery without direct physical contact.

Neurélux emits infrared wavelengths of 810 nanometers and 1,064 nanometers. The 810-nanometer wavelength stimulates mitochondrial activity in brain cells, supporting neuroprotection and regeneration while promoting ATP production to help reduce inflammation and support tissue recovery. The 1,064-nanometer wavelength penetrates more deeply into brain tissue, inducing gentle thermal stimulation and ion channel activation, thereby increasing blood flow and enhancing neuroplasticity. Through these mechanisms, Neurélux aims to improve cognitive functions such as concentration and working memory.

Additional features of Neurélux include consistent wavelength output during prolonged use and functional versatility, as the product can also operate as a standard lighting stand. Based on these combined capabilities, Korea Lighting plans to use CES 2026 as a launchpad to expand Neurélux into broader areas of brain health care, including sleep disorder management and cognitive function support.

Dongwoo Lee, CEO of Korea Lighting, said, “Neurélux was designed to help address Alzheimer’s disease and sleep disorders, which have emerged as major challenges in aging societies, by embedding brain health care naturally into daily life.” He added, “Our objective is to shift the market paradigm with the industry’s first non-contact brain healthcare solution.”

Lee continued, “CES 2026 marks the first global stage for Neurélux and provides an important opportunity to explore strategic partnerships with healthcare companies and buyers in North America and Europe. Throughout the exhibition, we will focus on demonstrating the product’s technological maturity and practical value.”

Through its debut of Neurélux at CES 2026, Korea Lighting signaled its ambition to position functional light semiconductors as a core technology for next-generation ambient healthcare solutions, while strengthening its presence in the global digital health and home healthcare markets.

Award-winning Ecoldbrew delivers smooth, freshly ground cold brew in five minutes, compatible with popular 40oz travel mugs.

IRVINE, CA, UNITED STATES, January 16, 2026 /EINPresswire.com/ — Ecoldbrew, a compact, fully automated cold brew coffee maker, has been named a Best of CES award winner by CNET, recognizing its breakthrough approach to making high-quality cold brew faster, easier, and more portable than ever before.

Instead of traditional hours-long steeping, Ecoldbrew lets users enjoy a smooth cold brew in about five minutes with minimal effort. Compatible with popular 40oz travel mugs – including Stanley tumblers – the device is about the size of a standard tumbler lid but packs in a grinder, brewing chamber, and circulation system all in one compact unit.

Simple to Use, Clever by Design
Ecoldbrew’s appeal lies in its simplicity. Like a regular bottle cap, the system screws onto a thermos or travel mug, instantly turning it into a cold brew setup. Inside, it stores whole bean coffee until you’re ready to brew. A dial on top lets you choose your grind size, and a central display tracks progress through each cycle. Press a button, and the device goes to work – grinding beans, pulling water from your mug, and cycling it back through the brew chamber.

The lid also features a flip-up bean compartment for refills and a built-in straw for sipping once brewing is complete. According to early feedback from coffee professionals who sampled Ecoldbrew at CES, the cold brew stood out for its smooth texture, clean mouthfeel, and balanced flavor, with a light natural foam forming on top when poured – a sign of freshly ground beans and active extraction. Reviewers noted that this foam contributes to a fuller body and creamier texture, qualities rarely found in traditional cold brew made through passive overnight steeping.

What Sets Ecoldbrew Apart
While many portable coffee makers focus on simplicity or speed alone, Ecoldbrew marries fresh grinding, controlled extraction, and portability in a way few competitors do. The system’s internal mechanism grinds beans right before brewing – a step most cold brew lovers say delivers a fresher, more aromatic cup.
Unlike bulky countertop brewers, Ecoldbrew doesn’t require extra accessories or counter space. It adapts to what you already carry and brings quality cold brew to offices, commutes, hikes, and travel without the usual wait.

Affordable and Accessible
The company is gearing up for a Kickstarter launch with models expected to start at around $99, making this technology more accessible than many traditional cold brew setups. Ecoldbrew’s approach suggests that good coffee shouldn’t be confined to cafés or kitchens – it should be portable, fast, and uncomplicated.

GA, UNITED STATES, January 16, 2026 /EINPresswire.com/ — Researchers introduce a new asset pricing factor called “emotional vulnerability” by combining large language models and network analysis of investor sentiment. By embedding stock forum texts and measuring network curvature, they show that emotionally vulnerable stocks tend to deliver lower returns, while emotionally stable stocks generate higher excess returns. The factor remains effective after controlling for traditional risk factors and sentiment direction.

Financial markets are increasingly shaped by investor emotions, yet most sentiment indicators focus only on whether investors feel optimistic or pessimistic. A new study published in Risk Sciences introduces a different perspective: instead of sentiment direction, it measures how fragile or unstable investor emotions are.

Researchers from the Central University of Finance and Economics in Beijing propose a novel concept called emotional vulnerability, which captures fluctuations and instability in market sentiment. The study combines large language models (LLMs) with network structure analysis to quantify this previously unexplored dimension of investor behavior.

The team analyzed millions of stock forum posts from China’s A-share market. Using the Moka Massive Mixed Embedding (M3E) model, an advanced large language model for Chinese text, they converted investor comments into numerical vectors. These vectors were then used to build sentiment networks for individual stocks, where connections reflect similarities in investor opinions.

“The vulnerability of each sentiment network was measured using Ricci curvature, a concept from geometry that has been widely applied in financial system risk analysis,” shares corresponding author Ning Zhang, a professor at the university. “In this context, higher curvature indicates tighter connections and more homogeneous investor sentiment, making markets more fragile when disrupted.”

The results showed that when emotional vulnerability is high, stock prices tend to fall or become unstable, whereas when emotional vulnerability is low, markets exhibit stronger resilience and generate higher excess returns.

“We also found that portfolios consisting of emotionally stable stocks consistently outperform those with high emotional vulnerability. This relationship remains significant even after controlling for traditional asset pricing factors, including the Fama–French five-factor model, as well as for sentiment direction (optimistic or pessimistic),” adds Zhang.

By shifting attention from sentiment direction to sentiment structure, the research expands the toolkit of empirical asset pricing. The authors suggest that emotional vulnerability can improve risk assessment, enhance market trend prediction, and support more informed investment decision-making.
