Which is better, water-cooled air compressor or air-cooled air compressor?

The cooling methods of screw air compressors are generally water-cooled and air-cooled. It is difficult to say which of these two methods is better or worse. It can only be said that it depends on what environment it is used in. JOY MACHINERY (SHANGHAI) CO.,LTD.  made a comparison of the two cooling methods of the air compressor for everyone to judge and choose by themselves.

Water-cooled screw air compressor, the cooling method is to use the fluidity and temperature difference of the cooling water to keep the temperature of the air compressor equipment within a certain range. Its advantages and disadvantages are as follows:

advantage:

1. Since the cooling water has a certain quality, when it flows inside the air compressor, it can clean the inside of the equipment. Help to prolong the maintenance and cleaning cycle of equipment and improve the quality of compressed gas;

2. The water-cooled screw air compressor has good adaptability to climate change. Increasing or decreasing the water pressure can adapt to strong changes in temperature;

3. In dusty environments, such as textile, spraying, carbon black, titanium dioxide and other industries, water-cooled is more reliable;

4. The cooler of the water-cooled screw air compressor, the oil side is easy to clean, but the air-cooled machine cannot.

shortcoming:

1. Restricted by water resources, the scope of application is relatively narrow;

2. The cooling water may contain calcium, magnesium and other ions, and these things are prone to chemical reactions in the cooler due to high temperature, and then form scale in the cooler, thus affecting the cooling efficiency of the cooler;

3. Water-cooled screw air compressors need to purchase cooling towers separately. This also increases procurement costs.

Air-cooled screw air compressor, the cooling method is to use the fluidity of the air to take away the heat, so that the air compressor is always kept in a suitable temperature range. Its advantages and disadvantages are as follows:

advantage:

The big advantage of the air-cooled cooling method is that it is not affected by environmental factors, and it can be used basically in any area.

shortcoming:

1. If the surrounding air quality is not good, it is easy to pollute the entire air compressor and compressed air. Therefore, in order to avoid such a situation, it is recommended to install filter equipment;

 2. If it is used in a closed space, it is recommended to install air intake and exhaust equipment;

3. The cooling effect and quality are not as good as the water-cooled type.

In summary, air-cooled screw air compressors and water-cooled screw air compressors have their own advantages and disadvantages. The air-cooled type has a simple structure and low investment, but due to limited conditions, the heat dissipation effect is relatively poor. Although the water-cooled type has a complex structure and high technical requirements, the heat dissipation effect is more significant.
