The difference between air-cooled and water-cooled cooling methods of screw air compressors

Air-cooled air compressor and water-cooled air compressor

1. There is no obvious difference between air-cooled air compressor and water-cooled in machine operating parameters, and both are suitable for long-term continuous operation.

2. The traditional concept of water cooling is better than air cooling. There are two reasons for this:

(1) Only a few of the technologies that can adopt air-cooling on large-displacement air compressors are complete, and the leading international companies in the process can do so. Therefore, many manufacturers who do not have this ability have long instilled water-cooling in their customers. The idea of  being superior to air-cooling forms the inertia of thinking.

(2) Ignore the long-term requirements of water-cooling methods for circulating water quality.


3. Advantages of air-cooled air compressor:

(1) Early-stage equipment investment and maintenance of the non-water cooling circulation system and the long-term dependence on the circulation system and water quality.

(2) There is no need to clean and maintain the water cooler of the air compressor regularly, which reduces the risk of shutdown due to maintenance.

(3) Reduced initial investment and equipment operation costs.

4. Matters needing attention when adopting air-cooling method: Air-cooling is dependent on air. The preliminary work is to make an air guide hood to export the intake and exhaust air of the air compressor to the outside of the engine room, which can avoid the high temperature due to the cooling air circulating in the engine room. The resulting over-temperature shutdown.
