Certified industrial components fabricated within our 12,000 m² high-precision Dezhou facility for turnkey overseas deployment.
A comprehensive engineering assessment of low-approach evaporative heat exchangers, closed-circuit loop integrity, and aerodynamically profiled air-induction dynamics.
The Gat Series introduces fluidic dispersion headers engineered with computerized numerical distribution orificing. This mitigates dry-spot formation along the PVC/PP micro-grooved infill packing, shrinking the thermal approach delta to within 2.8°C of ambient wet-bulb conditions without inducing fluid carryover.
Designed for closed-circuit applications, the Gat primary heat rejection coils utilize continuous serpentine red copper (TP2) or high-grade SUS316L alloy matrices. Each assembly undergoes a 2.5 MPa pneumatic nitrogen underwater immersion test to ensure zero porosity and eliminate scaling vectors entirely.
Equipped with forward-swept, adjustable-pitch aluminum alloy or FRP airfoils, our direct-drive or low-ratio belt induction drivetrains minimize vortex noise. Operating sound pressure ratings fall within 52–68 dB(A) at 10 meters, easily conforming to stringent municipal acoustic ordinances.
Modern mega-facilities require high reliability, reduced drift losses, and stable wet-bulb management across varying climates.
High-density semiconductor wafer fabs in East Asia require cooling loops with ±0.5°C temperature stability. The Gat Series delivers closed-loop fluid stability that prevents mineral accumulation within process chiller bundles.
Continuous induction furnace smelting requires rapid, high-volume heat dissipation without water scaling. Our closed-circuit Gat towers decouple process water from external contaminants, preventing furnace coil burnouts.
Coastal hydrocarbon refineries require structural resistance against salt-spray corrosion and chemical exposure. Our towers utilize vacuum-infused vinyl-ester FRP casings with 316 stainless structural fasteners.
Strategic R&D focused on lower carbon footprints, reduced water consumption, and intelligent operational monitoring.
Development of dual-pass drift eliminator arrays reducing drift loss to less than 0.0005% of circulating water volume, meeting stringent environmental standards.
Real-time Modbus/BACnet IoT transmitters embedded directly into bearings, fan motors, and sumps for predictive maintenance and vibration analysis.
Automated ambient air dry-cooling mode triggers during intermediate and winter seasons, reducing annual industrial water consumption by up to 60%.
Adopting bio-based resins and circular-economy composite frameworks to slash embodied carbon while maintaining a 30-year operational life.
Performance records across municipal, manufacturing, and commercial infrastructure projects globally.
Integrated municipal wastewater and clean processing facilities. Fengdun delivered high-capacity counterflow towers combined with SUS304 food-grade reservoirs to withstand tropical humidity and sustained biological activity.
Cooling infrastructure built for high-throughput injection molding machinery. Closed-circuit Gat towers maintain stable coolant temperatures under extreme monsoon heat, preventing hydraulic oil breakdown.
Engineered for a heavy minerals extraction plant. Features reinforced fiberglass reinforced polyester (FRP) structural profiles designed to resist volcanic airborne particulates and high concentrations of sulfur dioxide.

Direct technical answers addressing OEM capabilities, equipment selection, materials, and international logistics.
Fengdun is a verified original equipment manufacturer (OEM/ODM). All industrial cooling towers, HVAC mixed-flow fans, fire-rated smoke dampers, and modular stainless/enamel steel water tanks are fabricated in-house within our 12,000 m² heavy-machinery production complex located in Dezhou, Shandong, China. Overseas EPC contractors work directly with our engineering and production teams, avoiding third-party markups and streamlining quality control.
We provide full-spectrum engineering customization: shell materials (fiberglass reinforced polyester, hot-dip galvanized steel, SUS304, or SUS316L), dimensional constraints for tight plant rooms, fluid flow rates from 15 m³/h to 1,500+ m³/h per cell, localized electrical voltages/frequencies (380V/415V/460V at 50Hz/60Hz), variable fan-stack sound-attenuation cowls, explosion-proof motors (ATEX/IECEx compliant), and private labeling.
The choice depends on process cleanliness and fluid sensitivity. Open counterflow units offer lower initial capital outlay and suit standard HVAC chillers and general plant cooling where routine water treatment is available. Closed-circuit cooling towers isolate the process fluid inside sealed heat exchange coils, protecting it from atmospheric particulates and biological fouling. They are the ideal choice for induction smelting, data centers, and precision machinery.
SUS304 provides an economical, food-grade solution for commercial potable water storage, firefighting reserves, and standard HVAC expansion loops. SUS316 includes 2–3% molybdenum, which offers higher pitting and crevice corrosion resistance in coastal environments with high airborne chlorides, chlorinated process loops, or chemical processing sites.
Our manufacturing and quality systems comply with ISO 9001 and CE directives. Pre-shipment inspections by independent third parties such as SGS, Bureau Veritas (BV), or TÜV can be integrated into the inspection and test plan (ITP). Pressure boundary components undergo hydrostatic and pneumatic testing, with complete EN 10204 3.1 material test certificates (MTR) provided upon dispatch.
To accurately size equipment, please share: 1) Circulating water flow rate (m³/h or GPM); 2) Hot water inlet temperature (°C); 3) Cold water outlet target temperature (°C); 4) Local summer design wet-bulb temperature (°C); 5) Local power supply (voltage, phase, frequency); 6) Water chemistry profiles (chloride content, pH); and 7) Site dimensional or crane limits.
