With per-rack power densities scaling past 100 kW, traditional air-based cooling approaches have met their thermodynamic limits. High-performance liquid cooling systems are no longer optional—they are an architectural imperative.
Modern silicon architecture (such as advanced GPU architectures hosting large-scale LLMs like DeepSeek) easily pushes thermal envelopes beyond 700W to 1200W per accelerator. Achieving optimal chip junction temperatures requires custom micro-channel cold plates that feature ultra-low thermal resistance.
By routing dialectic fluids or glycol-water mixtures directly through custom cold plates engineered with skived copper micro-fins, our systems capture over 85% of total system heat directly at the source, dramatically reducing the dependence on energy-intensive air conditioning loops.
Engineered for high reliability, our custom CDUs manage secondary loop flow rates, filter particulates, and monitor dew points to prevent condensation. We integrate redundancy (N+1 or 2N pumps) and intelligent control systems that interface with data center DCIM platforms via SNMP or Modbus.
Zentraix Computing Technology Co., Ltd. is a professional manufacturer and solution provider specializing in AI GPU servers, high-performance computing (HPC) systems, GPU clusters, and customized AI infrastructure solutions. Established in 2016, Zentraix has rapidly grown into a trusted supplier serving global enterprises, research institutions, cloud service providers, and AI startups.
Located in Guangdong, China, our modern manufacturing facility covers over 3,800 square meters and integrates production, testing, assembly, and R&D operations under one roof. With years of expertise in AI computing hardware, we are committed to delivering reliable, scalable, and high-performance server solutions for AI training, inference, deep learning, big data analytics, and scientific computing.
We leverage our localized engineering ecosystem to offer complete customization including structural sheet-metal chassis fabrication, bespoke cold plate stamping, quick-turn PCB layout design for power and telemetry boards, and rack-level thermal testing. By managing both the computational node assembly and the cooling systems, Zentraix ensures absolute mechanical and thermal compatibility across the deployment cycle.
Rigorous quality assurance, a dedicated workforce, and a robust supply network form the foundation of our operations.
How our geographic position in Guangdong, China accelerates thermal engineering innovation while maintaining cost and schedule efficiencies.
Our location in Guangdong places us at the heart of the world's most advanced electronics hardware ecosystem. From raw copper and aluminum extrusions to precision CNC milling, rapid die-casting, and surface treatment facilities, we complete rapid prototyping iterations in days rather than weeks.
To ensure efficient manufacturing and stable supply capabilities, we maintain long-term partnerships with over 850 supply chain partners and component suppliers worldwide. This extensive network enables us to provide flexible production schedules, competitive pricing, and rapid delivery for both standard and custom projects.
Our facility houses an array of high-precision testing apparatus. We run continuous helium leak testing, hydrostatic pressure tests, and simulated environmental chambers to verify cooling performance under extreme ambient temperatures (up to 55°C) and varying humidity conditions.
We maintain high quality and reliability standards to meet international regulations and satisfy global enterprise procurement mandates.
Quality is at the core of everything we do. Our dedicated quality assurance department consists of 35 skilled inspectors who conduct comprehensive quality control procedures throughout the entire production process. Every server undergoes component verification, burn-in testing, performance benchmarking, thermal stability testing, compatibility testing, and final functional inspection before shipment.
For liquid cooling systems, our verification protocols are particularly rigorous. We perform dual hydrostatic pressure tests at 1.5 times the maximum rated operating pressure (up to 6 Bar) for 24 hours to ensure zero fluid loss. All quick-connect couplings, manifolds, and rubber hoses undergo material degradation and compatibility checks to guarantee a service life matching or exceeding the server lifecycle (typically 5 to 7 years).
Our infrastructure products conform to major international compliance standards, including CE, RoHS, FCC, UL, and CB. This guarantees seamless integration into corporate environments worldwide without violating local codes.
We work with clients to recommend, supply, and validate the chemical composition of secondary loop coolants. By utilizing corrosion inhibitors (such as benzotriazole) and biocide treatments, we prevent bio-fouling and galvanic corrosion between copper cold plates and aluminum manifolds.
To reduce risk for international buyers, Zentraix offers localized SLA support agreements. We maintain strategic warehouses containing replacement CDUs, pumps, manifolds, and pre-filled cooling modules across key regions (North America, Europe, and Asia-Pacific) to ensure minimal downtime.
As silicon architectures continue to push thermal thresholds, we are actively developing technologies to support next-generation compute racks.
Utilizing low-boiling-point dielectric fluids, two-phase cooling leverages latent heat of vaporization to extract heat from chips. This allows the system to handle extreme power densities (>1000W per GPU) while maintaining exceptionally low thermal resistance.
We are integrating machine learning algorithms directly into CDU microcontrollers. By analyzing real-time server telemetry (CPU/GPU utilization, thermal profiles), the CDU dynamically adjusts pump speeds and secondary loop temperatures before temperatures spike.
Our advanced secondary cooling loops are designed to capture heat at temperatures ranging from 50°C to 65°C. This high-grade waste heat can be diverted directly into municipal heating loops or used for industrial process preheating, helping operators achieve carbon-neutral data centers.
