Reliable OEM Compressed Air Dryer Manufacturer In China

Refrigeration dryers are the most commonly used dryers for removing moisture from compressed air. They therefore play an important role in shielding compressed air systems from corrosion and protecting your equipment and end products alike.

Professionally solve the problem of water and oil in compressed air.
Refrigerated air dryers, also known as refrigerated compressed air dryers, are designed to remove moisture from compressed air using the process of refrigeration. They work on a principle similar to that of a domestic refrigerator or air conditioning system, cooling the air to a temperature where the water vapor condenses into liquid form, which is then separated and removed from the air stream. 

How does a refrigerated air dryer work?

  • Pre-cooling: The incoming compressed air is first cooled in an air-to-air heat exchanger, where the outgoing cool dry air pre-cools the hot incoming air, condensing some of the moisture.
  • Refrigeration: The air then enters an air-to-refrigerant heat exchanger, where it is further cooled to a temperature as low as 3°C (35°F) by the refrigerant circuit, causing the moisture to condense into liquid water.
  • Moisture Removal: The condensed water is collected and removed from the system through an automatic drain.
  • Reheating: Finally, the dry and cold air is reheated by transferring heat from the incoming compressed air through the initial heat exchanger, preventing condensation in downstream pipelines and equipment. 
 

How many types of refrigerated air dryers?

Refrigerated air dryers can be categorized based on their cooling method:
  • Air-Cooled Refrigerated Air Dryers: Air-cooled type dryers use air to cool the refrigerant in the system. They are generally more straightforward to install and maintain but might be less efficient in very hot environments due to their reliance on ambient air.
  • Water-Cooled Refrigerated Air Dryers: Water-cooled type dryers use water to cool the refrigerant, which can be more efficient in maintaining consistent performance, especially in warmer environments. They require a water supply and may involve more complex installation and maintenance.
 

When and where do need refrigerated air dryers?

Refrigerated air dryers are ideal for applications that require a standard level of dry air and do not need to reach extremely low dew points. Refrigerated air dryers are well-suited for:  
  • General Manufacturing and Service Industries: For powering pneumatic tools and equipment where removing visible moisture is sufficient, refrigerated air dryers with a dew point around +38°F are typically adequate.
  • Automotive Shops: For everyday operations such as inflation, cleaning, and some painting processes, the air quality provided by refrigerated air dryers is adequate. They help prevent moisture-related issues without the need for the ultra-dry air that desiccant dryers provide.
  • Food Packaging Plants: In food processing, where compressed air is used in packaging but not in direct contact with food, refrigerated air dryers can prevent moisture that could lead to spoilage without the need for the lower dew points achievable by desiccant dryers.
  • Breweries: For operations that do not require ultra-dry air, such as some stages of the brewing process or for cleaning purposes, refrigerated air dryers ensure that the compressed air does not introduce moisture into the process.
 As a reliable manufacturer of refrigerator air dryers, Lingyu produces a wide range of refrigerated air dryers for air compressors, including water-cooled or air-cooled types. The extensive product portfolio of refrigerator dryers is of good quality with high stability, suitable for diverse applications and serving various needs.
