Compressed air purification solution (refrigerated air dryer)

Compressed air often carries a variety of pollutants, including moisture, oil, solid particles and harmful chemical impurities, which seriously affect system performance and equipment life.

Solid particles and oil will clog cylinders and pipes, causing system pressure to drop and pneumatic components to fail; and moisture not only corrodes metal parts and causes pneumatic components to fail, but also freezes in cold environments, causing pipes to freeze and crack.

Therefore, deep purification of compressed air is an indispensable part of industrial production. Efficient compressed air purification has far-reaching effects such as reducing equipment loss, avoiding product pollution, improving product quality, ensuring a healthy working environment, and preventing occupational diseases.

1. Reference plan for compressed air purification system selection (cold dryer)

Hongrijia YUKA has been deeply involved in the field of compressed air purification for more than 20 years. With its professional technical strength and rich industry experience, it provides customers with personalized and efficient compressed air solutions.

Different processes have different requirements for the dew point temperature of compressed air. For example, the pressure dew point of compressed air used for instruments is generally required to be below -40°C, while the pressure dew point of compressed air for semiconductor chip factories is required to be -70°C. However, in most cases, it is sufficient to require the dew point temperature of compressed air to be above 0°C. The dew point requirement of compressed air is usually achieved by a refrigerated dryer.

Cold dryer is the abbreviation of refrigerated dryer. The working principle is to use refrigerant to exchange heat with compressed air, reduce the temperature of compressed air to a dew point temperature in the range of 2-10°C, and remove moisture (water vapor component) in the compressed air.

By cooling and cooling, the water vapor in the compressed air is condensed into droplets, thereby achieving the purpose of reducing the moisture content. The condensed droplets are discharged from the machine through the automatic drainage system.

2. Advantages of YUKA cold dryer--HHL series integrated refrigerated dryer

1. Save space, the installation space is sharply reduced by 100%, and the whole machine is pre-installed with 1 GWS gas-water separator and 3 GHS series high-performance filters.

2. There is no need to install cumbersome air management on site, and it can be used by connecting the inlet/outlet normally, and the pipeline gas leakage is approximately equal to 0.

3. The self-developed composite heat exchanger is about 3% higher than the general plate heat exchange efficiency on the market, and is about 15-30% higher than the traditional shell and tube heat exchanger.
