Here are some precautions for the application of industrial air coolers:

1. Installation location: It should be selected in a well ventilated, dry, non corrosive gas and dust free place, avoiding installation in high temperature, humid or flammable environments.

2. Horizontal installation: Ensure that the air cooler is installed horizontally to ensure normal operation and reduce vibration noise.

3. Power supply: Connect a suitable power source, with voltage and frequency that meet the requirements of the air cooler, while ensuring stable power supply and avoiding excessive voltage fluctuations.

4. Air duct design: Reasonably design the air duct to avoid excessive length, bending, or small cross-sectional area, in order to reduce air resistance and improve cooling efficiency.

5. Regular maintenance: Regularly clean the filter screen, heat exchanger, and other components of the air cooler to prevent dust and debris from blocking and affecting the cooling performance and air volume.

6. Water quality management: If the air cooler uses water for cooling, attention should be paid to cleaning and softening the water quality to prevent scale and corrosion.

7. Component inspection: Regularly check the operating condition of components such as fans, water pumps, motors, etc. If there are any abnormal sounds, vibrations, or overheating, they should be repaired or replaced in a timely manner.

8. Safety protection: Provide good insulation and grounding protection for the electrical parts of the air cooler to prevent electric shock accidents.

9. Load matching: Select the appropriate cooling capacity of the air cooler according to actual needs to avoid excessive or insufficient load, which may affect the use effect and equipment life.

10. Operating standards: Operators should be familiar with the operating procedures of the air cooler to avoid malfunctions caused by misoperation.

I hope these precautions are helpful to you.
