Export-grade industrial solutions fabricated at our centralized 12,000 m² facility in Dezhou, Shandong. Complete compliance with international engineering procurement guidelines.
A comprehensive industrial white paper perspective on nominal cooling tonnage, aerothermal calculation matrices, and fluid dynamics in high-performance Chinese export towers.
A nominal 100-ton cooling capacity translates to dissipating 390,000 kcal/hr (15,000 BTU/hr per ton for standard HVAC chiller condensing heat load, or 3,000 kcal/h/RT). Sizing is executed strictly around water flow rate (typically 78 to 100 m³/h depending on approach), standard inlet 37°C, outlet 32°C, and a wet-bulb design benchmark of 28°C.
Using vacuum-formed virgin PVC or optional CPVC for elevated process fluid temperatures (>65°C), the patented cross-fluted chevron channels maximize liquid-to-air contact duration. The air-to-water ratio is optimized to 0.85–0.92 kg/kg, driving heat mass transfer rates upward while cutting static pressure losses by up to 18%.
Equipped with adjustable wide-chord extruded aluminum alloy or anti-corrosive FRP axial blades. High-efficiency IP55/IP65 TEFC low-noise motors combined with multi-groove V-belt drives or low-maintenance planetary gear reducers ensure mechanical reliability and acoustic pressure compliance under 62 dB(A) at 10 meters.
Deploying 100 Ton cooling towers across modern international infrastructure projects, precision manufacturing facilities, and heavy-duty process cooling systems.
Modular 100RT cooling cells integrate seamlessly with centralized chillers, offering N+1 redundancy, fine-tuned water balancing, and energy efficiency supporting PUE ratings under 1.25 in mission-critical server environments.
Closed-circuit 100 Ton towers protect hydraulic oil exchangers, mould cooling loops, and high-frequency induction furnaces against scaling, particulate clogging, and costly thermal downtime.
Featuring heavy-duty resin-rich FRP casings or hot-dip galvanized HDG/SUS304 structural frames, providing durable corrosion resistance against volatile chemical atmospheres and acidic washdowns.
Designed specifically for urban rooftops, shopping malls, and hospitals requiring acoustic sound attenuation options, low dynamic vibration, and strict drift losses held to less than 0.001% of circulating water.
The strategic advantage of sourcing from Shandong Fengdun Environmental Technology Co., Ltd. located in the world's most concentrated ventilation and thermal equipment cluster.
Our 12,000 m² facility features CNC high-precision fiber laser cutting, robotic welding cells, hydraulic CNC press brakes, and automated vacuum blister forming. This high-density automation eliminates manual dimensional variation and slashes structural production times by 40%.
Located in Dezhou, Shandong, raw materials including high-spec stainless steel coils, high-strength pultruded FRP profiles, and customized copper coils are sourced within a 30 km radius. Proximity to Qingdao and Tianjin deep-water maritime ports guarantees seamless multimodal logistics.
Every 100 Ton tower undergoes dynamic fan balancing to ISO 1940 G2.5 standards, motor insulation impedance testing, water basin hydrostatic leak verification, and comprehensive ultrasonic weld seam inspections prior to container stuffing and export departure.
Integrating digitalization, IoT condition monitoring, and sustainable water conservation across forward-looking global projects.
Real-time vibration sensors on fan drive bearings, basin water quality conductivity meters, and automated cycles of concentration (CoC) blowdown controls linked via Modbus/BACnet interfaces straight to building management systems (BMS).
Advanced cellular drift eliminator design reducing water loss to 0.0005%, paired with hybrid wet/dry finned heat transfer coils that eliminate winter visual plumes and reduce make-up water consumption by up to 25% during dry operation phases.
Transitioning away from gearboxes and drive belts toward variable-speed direct-drive permanent magnet synchronous motors. Eliminating mechanical transmission maintenance, cutting drive noise, and enhancing partial-load electrical efficiency across continuous operations.
Overcoming cross-border EPC friction through stringent compliance with global regulatory codes, third-party inspection agencies, and dedicated multilingual engineering support.

Essential technical, procurement, and logistical answers direct from Fengdun's export engineering department.
True capacity depends directly on wet-bulb temperature, water circulation rate, and approach (outlet temperature minus wet-bulb). We supply certified performance curves calculating the exact thermal load dissipated (in kcal/hr or kW) mapped against your site's specific microclimate conditions.
Open counterflow models deliver superior cost efficiency and a compact footprint for standard HVAC chillers with clean water loops. Closed circuit towers isolate the process fluid within sealed coils, making them mandatory for high-precision machinery, petrochemicals, or furnace loops vulnerable to air contamination and scaling.
We offer customized IP55/IP65 motors configured for 380V/415V/440V/480V at 50Hz or 60Hz. Options also include explosion-proof motors (ATEX/IECEx ratings), VFD-inverter-duty motors, and premium international brands like Siemens or ABB upon project specification.
Standard units use non-rotting, UV-inhibited fiberglass-reinforced polyester (FRP) with hot-dip galvanized internal structural steel. For corrosive sea air or chemical exposures, we manufacture full SUS304 or SUS316 stainless steel casings, structural frameworks, and specialized anti-algae PVC fills.
Units can be shipped fully assembled in flat-rack or open-top containers, or modularly knocked-down (CKD/SKD) into standard 40HQ containers to significantly reduce ocean freight costs. Clear visual assembly manuals, labeled sub-assemblies, and remote video technical supervision ensure smooth on-site installation.
Shipments include General Arrangement (GA) dimensional drawings, foundation load blueprints, electrical schematics, raw material mill test certificates (MTC), hydrostatic testing reports, fan dynamic balancing certs, and certificates of origin (CO/Form E) for preferential customs duty treatment.
Consolidate cooling towers with compatible water storage infrastructure, industrial mixed-flow blowers, and certified fire protection dampers directly from a verified Chinese manufacturer.
