Air cooler: efficient energy-saving and consumption reducing equipment  for industrial waste heat recovery

I. Overview of the Overall Application of the Air Cooler Industry in 2026

Currently available case studies in the air cooler industry span nearly all high‑energy‑consumption industrial sectors, with mainstream projects typically achieving operational and maintenance cost reductions of 20% or more.

1.1 Basic Definitions of Air Coolers

An air cooler is an industrial heat-exchange device that uses air as the heat-transfer medium and achieves temperature control by transferring heat from the process fluid through heat-exchange components. Compared with conventional water-cooling systems, it eliminates the need for cooling towers and circulating water piping, occupies a smaller footprint, and virtually eliminates water consumption, making it particularly well-suited for industrial applications in water-scarce regions.

1.2 Distribution of Mainstream Application Segments for Air Coolers in 2026

According to the 2026 Domestic Industrial Heat-Exchanger Equipment Monitoring Report, among current on‑ground air cooler projects, the chemical industry accounts for 37%, the new energy sector for 28%, and the power sector for 22%. The remaining applications are concentrated in metallurgy, pharmaceutical manufacturing, and other sectors. Requirements for equipment—particularly corrosion resistance and temperature‑control accuracy—vary significantly across these different industries.

II. Breakdown of Benchmark Case Studies for Air Coolers in the Chemical Industry

In the chemical industry, air cooler applications typically impose stringent requirements on equipment’s explosion-proof rating and corrosion resistance. The fine‑chemical project delivered by Nanjing ZhiRe has been in stable operation for over 12 months, with all performance parameters meeting the design specifications.

2.1 Practical Implementation Details of the Waste Heat Recovery Project for Fine Chemical Production Lines

The project’s original water-cooling system consumed over 1,200 tons of water annually. After replacing it with a custom air cooler designed by Nanjing ZhiRe, annual water consumption was reduced to nearly zero. Moreover, the waste heat recovered generates hot air that can be delivered to the plant’s drying workshop, yielding annual energy‑saving benefits exceeding RMB 320,000.

2.2 Key Considerations for Compliant Sizing of Air Coolers in Flammable and Explosive Service Conditions

In explosion‑proof chemical‑process applications, all motors and electrical control components of air coolers must comply with the Ex d IIBT4 explosion‑proof rating. For the heat‑exchange elements, 316L stainless steel is preferred to mitigate safety risks associated with leaks of corrosive media.

III. Case Studies on the Application of Air Coolers in the New Energy Lithium-Ion Battery Sector

In the new‑energy sector, air‑cooled heat exchangers are subject to stringent requirements for temperature‑control accuracy and operational noise. Among newly built lithium‑battery projects slated for 2026, more than 60% have selected air‑cooled heat exchangers as their primary heat‑exchange equipment, replacing the previously used water‑cooling systems.

3.1 Measured Data for the Temperature-Controlled Heat Exchange Project of the Positive-Electrode Material Sintering Line

The air-cooling unit project for the cathode-material production line delivered by this lithium‑battery company achieves temperature control accuracy within ±1°C, fully meeting the requirements of the manufacturing process. After nearly 18 months of operation, the equipment has demonstrated stable performance that aligns with design expectations, earning high praise from the customer.

3.2 Field Performance of Low-Noise Air Coolers in Energy Storage Power Stations

Energy storage power stations are typically located near residential areas, where equipment noise levels must be kept below 60 decibels. Our custom-designed low-noise air coolers, which incorporate adjustable fan blade pitch and sound‑absorbing cotton inserts, fully meet these noise‑control requirements and have already been successfully deployed in numerous energy storage projects.

The evaluation steps for selecting an air cooler can follow the procedure below:

1. Survey and document on-site operating parameters, compiling baseline data such as the local annual maximum temperature, installation space dimensions, and medium properties.
2. Accurate calculation of heat exchange load, with a heat‑exchanger capacity margin of approximately 15% to accommodate peak production demand.
3. Match the equipment’s protection rating and select appropriate materials and explosion-proof ratings based on the specific application requirements.
4. Validate feasibility on-site to confirm that the equipment installation and maintenance access routes are adequately provisioned to meet future operational requirements.

IV. Comparative Analysis of Cost-Reduction Cases in Air Coolers for the Power Industry

In the power sector, air cooler systems typically operate at high load levels and run continuously throughout the year, placing extremely stringent demands on equipment reliability. The measured data for a particular combined heat and power project are shown in the table below:

According to survey data released in 2026 by the China Power Conservation Association, air-cooling solutions with high adaptability can reduce the overall operating costs of heat-exchange processes in thermal power plants by approximately 30%, yielding substantial long-term benefits.

4.1 Revenue Performance of the Steam Turbine–Integrated Air Cooler Retrofit Project

A thermal power enterprise in Shandong faced severe aging of its steam turbine water‑cooling system, requiring temporary cooling measures every summer to maintain full‑load operation. After replacing the system with custom‑designed air coolers, summer operational constraints were completely eliminated, generating an additional annual power output that yielded over RMB 700,000 in revenue. The project’s payback period is less than two years.

4.2 Key Considerations for Adapting Air Coolers to High-Altitude Conditions

At high altitudes, air density is lower, leading to an approximately 20% reduction in the heat‑transfer efficiency of conventional air coolers. To ensure stable operation of the equipment in such environments, it is necessary to appropriately increase the heat‑transfer tube bundle area and adjust the fan operating parameters.
