Compressed Air Dryer Refrigerated

During operation, the humid compressed air first enters the precooler to exchange heat with low temperature air for initial cooling, and then enters the evaporator for further cooling with low temperature and low pressure refrigerant to condense water vapor into liquid water, and then enters the gas-liquid separator to separate liquid water by centrifugal force, gravity, etc. Finally, the heat exchange between the regenerator and hot air rises the temperature to avoid condensation in the transportation. Then the dry compressed air is transported to the gas equipment or storage device to meet the needs of industrial production.

Our Products Have Passed Various Certifications

 

1.Electronic component manufacturing: In the production process of electronic components, such as semiconductor chip manufacturing, circuit board assembly, etc., the dryness of compressed air is very high. Even trace amounts of moisture can cause short circuits, corrosion, or degraded performance of electronic components. The refrigerated dryer can effectively remove the moisture in the compressed air, providing a clean and dry environment for the manufacture of electronic components and ensuring product quality.

2.Electrical equipment assembly and testing: In the assembly workshop of electrical equipment, such as the assembly of TV sets, air conditioners and other electrical appliances, pneumatic tools and equipment need dry compressed air to ensure normal operation. At the same time, in the test of electrical products, dry compressed air can be used to simulate different environmental conditions to ensure that product performance meets standards.

3.Drug production: In the production process of drugs, whether it is the synthesis of raw materials or the production of preparations, a large amount of compressed air is required. For example, in the process of capsule filling and tablet pressing, the dry compressed air can prevent the drug from being damp and deteriorating, and ensure the quality and efficacy of the drug.

4.Painting industry: In the painting process of automobiles, furniture and other products, compressed air is used to drive the spray gun. If the air contains moisture, it will lead to problems such as bubbles and flow hanging in the paint, affecting the quality of the coating. The refrigerated dryer can remove the moisture in the compressed air, so that the paint is evenly sprayed on the surface of the object, improving the painting effect and the appearance quality of the product.

1. How to determine whether the drying effect of the dryer decreases?
You can observe whether there are problems caused by moisture in the gas equipment, such as whether the pneumatic tool is rusty, whether the painting bubbles, and whether the electronic equipment is short-circuited due to humidity. It is also possible to directly measure the dew point temperature of compressed air by installing a dew point meter. If the dew point temperature rises significantly, the drying effect decreases.

2. Can it be used in clean rooms with high air quality requirements?
It can be used as an important part of removing water, but it is usually necessary to cooperate with other air purification equipment, such as high efficiency filters, adsorption dryers, etc., to further remove dust, oil and other impurities in order to meet the strict requirements of clean room air quality.

3. How can we reduce the energy consumption of the dryer?
Excessive drying can be avoided by adjusting the working load of the dryer according to the actual gas demand. In addition, regularly clean the dust and dirt on the surface of the heat exchanger to ensure good heat dissipation, which can improve the heat exchange efficiency and reduce energy waste. At the same time, set the cooling temperature reasonably to avoid increasing energy consumption due to setting too low dew point temperature.

4. How often does this air dryer need maintenance?
Full maintenance is generally recommended every 3-6 months. This includes checking refrigerant pressure and level, cleaning or replacing air filters, checking for smooth drainage systems, and cleaning critical components such as evaporators and condensers. However, if the use environment is harsh or the frequency of use is high, the maintenance period should be appropriately shortened.
