YHRD Series Refrigerated Air Dryer
YHRD Series High Pressure Refrigerated Air Dryer: Efficient Moisture Removal for High-Pressure Compressed Air Systems
Introduction
In industries where compressed air plays an important role in production and processing, maintaining air quality is essential. Moisture present in compressed air can affect equipment performance, reduce operational efficiency, and create problems in various industrial applications. The YHRD Series High Pressure Refrigerated Air Dryer is designed to remove moisture from compressed air and deliver clean, dry air for demanding industrial operations.
The YHRD Series uses a traditional yet effective copper tube-in-tube heat exchanger design. This system works on a coaxial heat exchange principle, where one copper tube is positioned inside another to facilitate efficient heat transfer. Its construction supports durability, thermal efficiency, and corrosion resistance, making it suitable for high-pressure compressed air applications.
With operating pressure capabilities of up to 40 bar and capacity ranges from 25 CFM to 1500 CFM, the YHRD Series offers a reliable solution for industries requiring consistent compressed air quality.
What Is a YHRD Series High Pressure Refrigerated Air Dryer?
A YHRD Series High Pressure Refrigerated Air Dryer is an industrial air treatment system designed to remove moisture from compressed air operating under high-pressure conditions.
During air compression, moisture remains present in the compressed air. If this moisture is not removed, it can affect connected machinery, pneumatic systems, and industrial processes. The refrigerated air dryer cools the compressed air to approximately +3°C, allowing moisture to condense into liquid droplets.
These droplets are then separated from the compressed air and automatically drained through an Automatic Drain Valve.
The YHRD Series is specifically developed for applications requiring high-pressure compressed air, with the ability to operate at pressures up to 40 bar.
Working Principle of YHRD Series Refrigerated Air Dryer
The YHRD Series operates through a refrigeration-based moisture removal process using air-to-air and Freon heat exchangers.
The working process involves the following stages:
Entry of Warm Compressed Air
Warm compressed air enters the air-to-air heat exchanger. At this stage, the incoming air transfers heat to the outgoing cold, dry compressed air.
This pre-cooling process reduces the temperature of the incoming air before it enters the refrigeration section.
Cooling Through the Freon Heat Exchanger
After pre-cooling, the compressed air enters the Freon Heat Exchanger, where it is further cooled to approximately +3°C.
At this temperature, the moisture present in compressed air condenses into liquid droplets.
Moisture Separation
The condensed moisture is separated from the compressed air using a highly efficient demister. This helps remove liquid water from the air stream.
Automatic Moisture Drainage
The separated water is automatically discharged through an Automatic Drain Valve, reducing the need for manual moisture removal.
Reheating of Dry Compressed Air
The cold, dry compressed air passes through the secondary side of the air-to-air heat exchanger. Here, it absorbs heat from the incoming warm compressed air.
This reheating process increases the outlet air temperature while maintaining its dry condition.
Delivery of Dry Compressed Air
Finally, the treated compressed air is delivered for instrumentation and industrial process applications.
This complete process helps maintain a consistent dew point and supports reliable compressed air performance.
