Combination low-dew-point compressed air dryer: a highly efficient air drying solution

In industrial production, the quality of compressed air is directly related to product quality, equipment lifespan, and production efficiency. Hangzhou Juko Air Separation Equipment Manufacturing Co., Ltd.'s KCD combined low-dew-point compressed air dryer, with its advanced technology and excellent performance, is the ideal choice for many companies to ensure compressed air quality.

I. Working Principle

The KCD combined low-dew-point compressed air dryer integrates the advantages of refrigeration dryers and adsorption dryers. Through scientifically reasonable pipeline connections and capacity matching, it achieves a highly efficient air drying process.

High-temperature, high-humidity compressed air from the compressor first enters the heat exchanger, where it undergoes heat exchange with the already dried low-temperature compressed air to initially lower the temperature. Next, the air enters the evaporator, where most of the gaseous water condenses into liquid water and is discharged outside the machine through a drainage device. The compressed air with very low humidity after preliminary dehumidification then enters the adsorption cylinder, where the adsorbent performs deep drying and dehumidification to obtain finished air with a lower dew point. Finally, the low-temperature dried compressed air re-enters the heat exchanger, cooling the incoming high-temperature, high-humidity air and raising its own temperature. This prevents condensation outside the delivery pipeline and uses a small portion of the warmed compressed air for adsorbent regeneration, effectively improving regeneration efficiency and reducing energy consumption.

II. Performance Parameters

Operating Pressure:

The standard operating pressure range is 0.6 - 0.8Mpa, and equipment with an operating pressure of 1.0 - 3.0Mpa can also be provided according to the company's special needs.

Inlet Air Temperature:

The inlet air temperature must be below 45℃ to ensure normal operation and high drying efficiency of the equipment.

Cooling Method:

Both water cooling and air cooling methods are available. Companies can choose according to their actual operating conditions and environmental conditions. Water cooling is suitable for places with sufficient water sources and higher ambient temperatures, providing stable cooling effects; air cooling offers the advantages of convenient installation and no need for additional water sources, suitable for scenarios with limited water sources or strict requirements for installation space.

Finished Air Dew Point:

This dryer can achieve a low dew point of -60℃ to -70℃, meeting the extremely high requirements for compressed air quality in production processes.

Inlet Water Temperature and Pressure (Water-cooled type):

The inlet water temperature must be ≤32℃, and the inlet water pressure must be between 0.2 - 0.4Mpa to ensure the normal operation and cooling effect of the water cooling system.

Regeneration Air Consumption:

Regeneration air consumption is only 3-6%, effectively reducing operating costs and improving energy efficiency.

III. Application Scenarios

Electronics Manufacturing Industry:

In the manufacturing of electronic chips and electronic components, the purity and dryness of compressed air are extremely high. The KCD combined low-dew-point compressed air dryer can provide high-quality compressed air that is low-dew-point, dust-free, and oil-free, preventing electronic components from experiencing performance degradation or short circuits due to moisture or contamination, ensuring high-precision manufacturing and stable performance of electronic products.

Pharmaceutical Industry:

Drug production must follow strict GMP standards, and compressed air quality directly affects drug quality and safety. This dryer effectively removes moisture and microorganisms from compressed air, preventing contamination during drug production and packaging, ensuring drug quality and stability, and meeting the stringent requirements of the pharmaceutical industry for the production environment.

Food Processing Industry:

The shelf life, taste, and quality of food are closely related to the quality of compressed air during the production process. The KCD dryer prevents moisture and contaminants in compressed air from mixing into food, preventing food from becoming damp, deteriorating, or breeding bacteria, ensuring hygiene and safety during food processing, and extending the shelf life of food.

Automotive Manufacturing Industry:

From the precision manufacturing of automotive parts to the painting process of complete vehicles, high-precision and stable compressed air is required. This equipment can provide high-quality dry compressed air for automotive manufacturing, ensuring the precision of parts processing, improving the automotive painting effect, preventing defects such as bubbles and sagging in the paint surface, and improving the overall quality and appearance of automobiles.

Chemical Industry:

In chemical production, many processes have strict requirements for the dew point and purity of compressed air. The KCD combined low-dew-point compressed air dryer can meet the needs of chemical processes for dry air, ensuring the stability and product quality of chemical reactions, and preventing equipment corrosion and pipeline blockages caused by compressed air problems.
