Industrial Air Cooler & Air Cooled Heat Exchanger Manufacturer | Yuhong Group

Yuhong Group Co., Ltd. is a world-class designer and manufacturer of high-performance thermal processing equipment, including custom shell and tube heat exchanger units, heavy-duty pressure vessels, and industrial air cooled heat exchangers (air coolers). Operating out of state-of-the-art manufacturing facilities, we deliver engineered thermal solutions for oil refineries, petrochemical plants, natural gas processing facilities, and thermal power stations globally.

Beyond complete air cooling systems, Yuhong Group is a premier supplier of critical replacement parts. We supply high-precision finned tube bundle units, u tube bundle assemblies, seamless heat exchanger tubes, heavy-section heat exchanger tubesheet plates, headers, and structural components for existing field retrofits.

An air cooler (air-cooled heat exchanger) is an eco-friendly heat rejection system that utilizes ambient air to cool process fluids inside finned tube bundles. Unlike water-cooled shell & tube heat exchanger systems, air coolers require zero cooling water consumption, making them the industry standard for arid locations, remote refineries, and environmentally sensitive chemical processing plants.

Our air cooler units consist of four main engineered modules: the heat transfer surface (finned tube bundle), the air movement assembly (axial fans, motors, and plenum chambers), the heavy-duty structural steel frame, and precise pressure/temperature control instrumentation.

We engineer and build air coolers tailored to your process metallurgy and field space limitations:

• Forced Draft Air Coolers: The fans are located below the tube bundle. This configuration offers easy fan maintenance, protection of mechanical components from hot exhaust air, and simple installation of structural support frames.

• Induced Draft Air Coolers: The fans are positioned above the tube bundle. This design provides superior airflow distribution across the finned surface, prevents thermal air recirculation, and protects the bundle against rain, hail, and solar heating.

• V-Frame / A-Frame Air Coolers: Space-saving inclined designs optimized for power generation condensation units and high-capacity gas processing terminals.

• Zero Water Consumption & Low Operating Costs: Eliminates water treatment, scaling, thermal water pollution, and cooling tower maintenance required by traditional water-cooled heat exchangers.

• Superior Mechanical Integrity: Every tube bundle undergoes strict NDT inspection and high-pressure hydrostatic testing to ensure zero-leak performance under thermal cycling.

• Modular Pre-Assembly & Easy Site Erection: Frame structures, plenum chambers, and fan ring modules are pre-fitted in our factory to guarantee fast field installation and minimal site downtime.

• Direct Drop-In Replacement: We custom manufacture finned tube bundle assemblies and replacement headers designed to fit directly into existing shell and tube heat exchanger bays or air cooler banks.

When specifying or retrofitting an air cooler, consulting engineers and procurement managers should evaluate the following parameters to ensure optimal thermal efficiency:

1. Fin Selection for Ambient Environments: Extruded aluminum fins completely sheath the base tube, preventing atmospheric corrosion and moisture ingress on the base tube outer wall—ideal for offshore or highly humid refining sites.

2. Thermal Expansion Protection: High-temperature process streams require floating header designs or u tube bundle options to absorb differential thermal expansion between the tubes and structural steel frames without straining the heat exchanger tubesheet weld joints.

3. Winterization & Temperature Control: For cold climate operation, air coolers should be equipped with louvers, variable pitch fans, or recirculation bays to prevent process fluid freezing or hydrate formation during winter months.

Our air cooler systems and replacement tube bundle units are operational in:

• Petroleum Refining: Overhead condensers, heavy gas oil coolers, hydrotreater effluent coolers, vacuum residue cooling.

• Natural Gas Processing: Gas compressor station intercoolers/aftercoolers, dehydration plants, NGL extraction, LNG liquefaction trains.

• Petrochemical & Chemical: Ethylene plant coolers, aromatics units, ammonia synthesis cooling loops.

• Power & Energy: Steam turbine condenser air coolers (ACC), geothermal power plant heat rejection.
