GSA's compressed air treating equipment turning Top air quality
With a high-efficiency aluminum heat exchanger, GSA refrigerated air dryer offers great dehumidifying performances and stable dew points with a larger heat exchange area and greater efficiency than other types of heat exchangers.
SA’s aluminum heat exchanger is divided into three different parts: i) air-air heat exchanger, ii) air-refrigerant heat exchanger, iii) 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.

High-efficiency Aluminum Heat Exchanger
With a high-efficiency aluminum heat exchanger, GSA refrigerated air dryer offers stable dew points with a larger heat-exchange area and greater efficiency than other types of heat exchangers such as shell & tube and plate ones. Made with the same material, the GSA air dryer has no thermal resistance and is free from heat exchanger freeze-up or corrosion.
Highly Reliable Drain
without Compressed Air Loss
With a demister and a large separator inside the heat exchanger, it offers great condensate isolation efficiency. The isolated condensate is discharged through a magnetic float or level sensor-based electronic drain, ensuring great efficiency and operating performances. Therefore, it reduces performance drop or failure in the drain caused by oil or various contaminants.
MEPOL Inner Pipe
The high-temperature dryer is durable and anti-corrosion, featuring a cooler, a filter, a dryer and MEPOL pipe. Therefore, it can prevent pipe corrosion and microbial/bacterial formation. With great mechanical strength and pressure resistance, it reduced a risk of rupture caused by shock or fluid. With anti-scale properties, furthermore, it keeps the flow constant and reduces a possibility of differential pressure. The compact design also minimizes a design area.
Efficiency Maximization with High-efficiency Condenser
For stable performances even under unfavorable circumstances such as high temperature, grooved cooper tube and corrugated split fin were applied. Since they are expanded in a complete and uniform manner, fin adhesion is high, applying condensate with a high coefficient of heat transfer. Therefore, it guarantees stable operations under diverse environments including hot temperature.
Smart and Simple Controller
The simple and functional controller helps users read the exact dew points. It is able to check if an after-cooler functions properly with power supply. In addition, it automatically controls an after-cooler by temperature, reducing unnecessary power consumption. A 4.3” TFT color touch panel controller enables simple and easy management, featuring digital dew point display, refrigerant pressure transmitter-based smart control, diverse temperature information, reverse phase check and mobile communication features (option) such as WIFI and BT.
A high-temperature refrigerated air dryerfeatures an after-cooler and a filter. It does not need any separate piping works for an after-cooler/filter installation. In addition, the compact design ensures easy and convenientinstallation even in a small space. With an particle filter and an oil filter, in addition, this system provides high-quality compressed air without an addition of facilities.
Minimizing the loss of compressed air
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, making it possible to operate the compressed air system more efficiently at lower costs.
