LEARN MORE →The global surge in Artificial Intelligence (AI), Large Language Model (LLM) training, neural network inferencing, and high-performance computing (HPC) has fundamentally reshaped data center architecture. Traditional enterprise data centers were engineered around power densities ranging between 5 kW to 15 kW per rack. In stark contrast, modern AI server architectures—powered by ultra-dense GPU arrays (such as NVIDIA H100, H200, B200, and Blackwell NVL72 platforms)—drive rack power densities well past 40 kW, 80 kW, and up to 120 kW+ per enclosure.
At these extreme power densities, conventional air-cooled computer room air handlers (CRAH) and computer room air conditioners (CRAC) reach physical and thermodynamic limits. Air alone cannot transport heat away quickly enough to prevent thermal throttling of high-wattage microprocessors. As a direct consequence, the modern data center industry is rapidly adopting hybrid cooling architectures—coupling direct-to-chip (DLC) liquid cold plates and rear-door heat exchangers with heavy-duty exterior cooling tower infrastructure capable of continuous, massive kilowatt-to-megawatt heat rejection.
Enables wet-bulb economizer operation and free cooling modes, slashing mechanical chiller runtime and driving enterprise Power Usage Effectiveness (PUE) below 1.15.
Hermetically sealed heat exchange coils eliminate scale, biological fouling, and airborne particles, protecting high-value Coolant Distribution Units (CDUs) and server cold plates.
Redundant EC/VFD motor drives, corrosion-resistant FRP/stainless enclosures, and multi-cell configurations guarantee non-stop heat rejection during continuous AI training workloads.
In AI data facilities, cooling systems are no longer treated merely as auxiliary building utilities; they are mission-critical computing enablers. A single cluster containing tens of thousands of accelerated processors produces immense thermal loads that must be dissipated instantaneously. Thermal instability can lead to computational latency, chip throttling, silent data corruption, or catastrophic server shutdown.
Cooling towers serve as the ultimate thermal bridge between the internal primary/secondary chilled water loops (or CDU fluid networks) and the external ambient atmosphere. By utilizing the evaporative potential of ambient air, evaporative cooling towers deliver far lower approach temperatures than air-cooled chillers or dry coolers, achieving supply water temperatures very close to the ambient wet-bulb temperature. This thermodynamic advantage allows data center operators to maximize free-cooling hours, dramatically diminish mechanical compression energy, and meet stringent carbon neutrality goals.
Deploying the correct cooling tower topology is vital when designing an AI computing facility. Factors such as water quality control, climatic humidity, footprint limitations, and operational redundancy dictate whether an open counterflow configuration or a closed-circuit evaporative system is optimal.
The internal process fluid circulates exclusively inside a hermetically sealed coil bundle. Spray water cascades over the exterior coil surface while induced air facilitates heat rejection. This design ensures that the data center’s primary loop water never comes into contact with ambient air, completely eliminating dust, airborne debris, bacteria, and oxidation from entering the delicate Coolant Distribution Units (CDUs) or water-cooled chillers.
Warm condenser water is distributed across high-efficiency PVC film fill packs, descending directly against upward-flowing ambient air. This configuration yields optimal heat transfer surface area per square meter, exceptional energy efficiency, and compact footprints. Paired with plate-and-frame heat exchangers, open counterflow towers provide immense megawatt heat transfer capacity at highly attractive capital expenditures.
During mild or cold seasons, cooling towers operate in dry or free-cooling economizer mode, routing chilled water directly into heat exchangers without energizing mechanical compressors. When ambient temperatures rise, water spray systems modulate automatically to provide evaporative cooling, ensuring minimal Water Usage Effectiveness (WUE) while maintaining strict temperature compliance.
As server racks transition to cold plates handling 70%–85% of total chip heat via treated warm water loops (e.g., ASHRAE W3/W4 classes at 32°C–45°C supply temperatures), cooling towers can dissipate this warm water directly into the ambient environment year-round without running power-hungry chillers, slashing thermal facility OPEX by over 40%.
Cooling towers supporting AI workloads require structural and mechanical engineering far beyond standard commercial HVAC units:
Shandong Fengdun Environmental Technology Co., Ltd. is located in Luquantun Industrial Development Zone, Dezhou City. It is adjacent to the Beijing-Kowloon artery to the east, the provincial capital Jinan to the south, and the Beijing-Hangzhou Canal to the north, with convenient transportation and fast communication. The company has a strong professional R&D team, and "Feng Shield" has also become a well-known brand in the ventilation and cooling equipment manufacturing industry.

Cooling tower equipment must adapt to multifaceted topologies depending on geography, server architecture, and operational scale. Below is an in-depth breakdown of how our cooling tower systems integrate across modern high-density compute facilities:
Hyperscale campuses running continuous distributed LLM training workloads require 50 MW to 300+ MW of aggregate thermal rejection. In these installations, multi-cell modular industrial square counterflow cooling towers are deployed in N+1 or 2N redundant banks. The modular design enables fast phase-by-phase scaling as compute capacity expands, while automated PLC-controlled chemical dosing and filtration systems maintain exceptional water conductivity and heat transfer efficiency.
Immersion cooling involves submerging entire server blades in dielectric fluid. The heat absorbed by the dielectric fluid is transferred to a water loop via an external plate heat exchanger. The exterior water loop is continuously cooled by closed-circuit cooling towers. Because dielectric fluid loops demand ultra-stable operating temperatures to maintain optimal fluid viscosity and boiling points, the closed cooling tower's precise temperature regulation is essential for preventing server failure.
Edge AI data centers located at telecommunication towers, autonomous vehicle hubs, and smart manufacturing plants require compact, self-contained cooling setups. Compact FRP counterflow towers and compact closed-loop cooling towers provide the ideal combination of low physical footprint, low operating noise, high structural resilience against harsh weather, and plug-and-play installation.
In hot and dry climates, conventional air-cooled chillers suffer severe performance degradation as ambient dry-bulb temperatures soar above 40°C. In contrast, evaporative cooling towers capitalize on the low wet-bulb depression inherent in dry climates, delivering cool circulating water below 28°C even in intense desert heat. This resilience makes cooling towers the primary choice for data center corridors established across the Middle East, Central Asia, and Southwestern North America.
