Why Refrigerated Air Dryer ?

Why Refrigerated Air Dryer ?

Compressed air dryer is as important as air compressors in order to keep your air system running at peak efficiency. All compressed air systems suffer from the common problems of dirt, oil and water contamination entering the system. These are intensified when air is compressed.
Fine particles and oil shall be removed by compressed air filters while condensate needs to be removed properly by a refrigerated/desiccant air dryer. Failure to remove these contaminents will result in serious problems within the compressed air system, such as pipe corrosion and damaged pneumatic equipment. So the moisture shall be removed effectively from indoor air lines resulting in reducing maintenance costs associated with air line contamination.

In general, a refrigerated air dryer offers 2-10℃ of pressure dew point (-22 thru -17℃ in atmospheric pressure dew point). This machine is installed in processes where low-dew point is unnecessary such as semiconductor, food & drink and pharmaceutical industry. With great dehumidifying effects, it will keep your air system working at peak efficiently.

GSA Refrigerated Air Dryer

GSA uses a high-efficiency aluminum heat exchanger. The area of heat exchanging of the dryer is greater than that of other types of heat exchangers. Therefore, it can offer great dehumidifying performances with high efficiency and stable dew points

GSA’s aluminum heat exchanger is divided by three different sections: the first is for air-air heat exchanging, the second is for air-refrigerant heat exchanging and the third is the oversized demister separator for removing moisture from the compressed air cooled in the second heat exchanger.

The first section of the heat exchanger reduces electrical energy with decreasing load of the refrigerant compressor by exchanging the heat of the hot inlet air and cold compressed air cooled down to the dew point in the second section of the heat exchanger. The cold compressed air cooled down to the dew point meets hot inlet air from the air compressor, and increases the outlet temperature of the compressed air. As a result, it can prevent pipes from sweating. The oversized demister separator enhances dehumidifying performances by removing condensate efficiently from the humid compressed air cooled down in the second section of the heat exchanger.

GSA Refrigerated Air Dryer

ISO 8573-1:2010 is an international standard for rating the quality of compressed air. It offers quantified guideline of contaminants in the compressed air including solid particles, moisture and oil. The compressed air quality rating is applied strictly to various industrial fields where high quality standards and requirements are essential such as food, drinks, medicine, spinning & weaving and electronics.

GSA refrigerated air dryers, designed with the latest technologies and extensive manufacturing knowhow offer more advanced features and performance guarantees than other brands on the market. GSA guarantees a constant dew point to keep compressed air systems operating at peak efficiency meeting ISO8573.1 Compressed Air Quality Class IV-V.

Highly Reliable Refrigerated Air Dryer

Diverse Innovative Technologies

aluminum heat exchanger

High-efficiency Aluminum Heat Exchanger

With a high-efficiency aluminum heat exchanger, GSA refrigerated air dryer offer larger heat-exchange area and performance guarantees of stable dew point than any other brands adopting other types of heat exchangers such as shell & tube and plate ones. Made with the same material, GSA air dryer has no thermal resistance and is free from heat exchangerfreeze-up or corrosion.

Efficient Condensate Separation

Alargervolumeofthedemister-installed separator can separate a large volume of condensate efficiently. Therefore, GSA refrigerated air dyers deliver stable performances and dew points even under diverse load and pressure.

low differential pressure

Minimization of Compressed Air Loss with Low Differential Pressure

We minimized differential pressure with a large heat-exchange area and sufficient cross section for the passage of compressed air. We enhanced heat-exchange efficiency and reduced differential pressure by minimizing resistance. As a result, the GSA dryer performs the enhanced efficiency of the compressed air system with lower operating costs.

Smart-and-Simple-Controller

Smart and Simple Controller

The simple and functional controller helpsusers readthe exactdewpoints. In addition, it is easy to check energy savings through the ECO lamp. In addition, diverse controllers featuring a 4.3” color TFT touch panel and mobile communication specifications (WIFI, BT) are also offered as an option.

Highly Reliable Drain without Compressed Air Loss

Highly Reliable Drain without Compressed Air Loss

An auto drain featuring a magnetic float which is free from compressed air loss is applied, enhancing the efficiency of compressed air facilities. The magnetic float ensures great operating performances and minimizes performance drop orfailure in the drain caused by oil, dirt and various contaminants.

High efficiency condenser

Efficiency Maximization with High-efficiency Condenser

For stable performances even under unfavorable circumstances in tropics, we adopted grooved copper tubes and corrugated split fins. In addition, we use a condenserperforminghighheattransfer coefficient under great fin tightness withcompleteanduniformexpansionof the tube. GSA refrigerated compressed air dryers are performance-proven under diverse area including tropics.
