What is the difference between air-cooled and water-cooled air compressors?

01

What is an air-cooled air compressor? What is a water-cooled air compressor?

Air-cooled air compressors introduce cold air from the outside, use fans and fin coolers to dissipate heat, and use air to cool the lubricating oil and cool the machine. , inside the water) to carry out heat exchange with water to achieve cooling effect.

02

Air and cold water in common

The operating parameters of the machine are consistent, and they are all suitable for long-term continuous operation.

03

What is the difference between air and cold water?

Different cooling methods

Air-cooled air compressors generally have air inlets. Intuitively, the air-cooled air compressor has many fins to dissipate heat and is blown by a fan. The water-cooled air compressor needs to cool the equipment shell with water for cooling, and can use pure tap water, demineralized industrial water, etc.

The cost of the station building is different

Because the air-cooled station house does not need to add additional water cooling devices, and the water-cooled station house needs to be equipped with a cooling water tower or other cold water source, the purchase cost is relatively higher, but the cooling effect is better. Therefore, the general water-cooled air compressor will adopt the method of circulating cooling for the sake of saving.

04

Air-cooled air compressors consider ventilation

Space issues need to be considered during installation. In order to avoid hot air circulation, a large cooling space needs to be vacated (the compressor installation space is large), and an air duct needs to be installed if necessary.

Air-cooled maintenance is simple, but affected by the environment, in the production conditions with poor ventilation or large dust, regular dust removal and cleaning are required, and the heat dissipation surface is easily covered by dust, causing blockage of the heat dissipation system, affecting the cooling effect, and even causing equipment damage. high temperature.

For large indoor air-cooled air compressors, the maintenance cycle preset by the radiator manufacturer can be maintained normally. At the same time, the air-cooled machine is usually equipped with an air duct to exchange heat with the outdoor air, so as to achieve the effect of cooling and ventilation.

05

Water-cooled air compressors consider water quality

The cooling water of the water-cooled air compressor has a certain cleaning effect, so when it flows inside the air compressor, it can clean the inside of the equipment, which helps to prolong the maintenance and cleaning cycle of the equipment. Compared with air cooling, the cooling water is faster and more efficient. higher.

▲The water cooler is under maintenance

There is one more cooling water tower or cold water source in the water-cooled station, which requires regular maintenance, which is one more maintenance procedure than the air-cooled machine.

The water-cooled air compressor must use relatively clean industrial cooling water, and the inlet water temperature is lower than 32 °C to avoid the scaling and blockage of the cooler. Generally, the water side of the cooler is cleaned within 1500 hours.
06

How to choose air-cooled cooling?

The water cooler is more adaptable to climate change, and different water pressures can adapt to changes in temperature;

Dusty production conditions, such as textile, spraying, cement and other industries, the water cooler is more reliable;

The noise of the water-cooled machine is relatively lower than that of the air-cooled machine, which can meet the larger processing capacity;

The ventilation conditions are good, and it is more suitable to choose an air cooler with installation space.
