Delivery of GSA’s GCBD Combination air dryer
Today, I would like to share with you the GCBD combination dryer delivery that took place at our company in November 2023. By introducing this facility, the end-user is able to save 440 million won (appox. 400,000 USD) in annual electricity bills.

Now that not only the cost of various raw materials but also the cost of electricity has skyrocketed, many companies are doing their best to reduce electricity costs. Energy saving has now become an important production factor that can determine the survival of a company rather than just an option.

Significant reduction in electricity costs can be realized simply by using a combination dryer. A combination dryer is the best choice not only for the companies planning new installations in case of using compressed air in large quantities but also for the companies considering replacing existing facilities because they are already outdated.


Many people may be unfamiliar with the term combination dryers. Combination dryers offer incredible energy savings compared to using a desiccant dryer alone or simply using a desiccant and refrigerated dryer in parallel.


In case of a combination drying system, a combination refrigerated dryer is used to dry the compressed air entering the adsorption dryer to a pressure dew point of 4°C. As a result, the load on the adsorbent is reduced incomparably with untreated compressed air.


The thermodynamic and mechanical stresses acting on the GCBD adsorption dryer are greatly reduced. So the service life of the adsorbent be dramatically can be extended, and the amount of adsorbent filling is also reduced, resulting in minimizing maintenance costs.


If you are looking for a highly energy-efficient pressure dew point -40°C/-70°C compressed air treatment solution, try GSA Co., Ltd.’s “GCBD” combination dryer.

This is the site where combination refrigeration dryers are being manufactured. Two high-performance axial fans boasting powerful performance are mounted on the top of the dryer, so the heat generated inside the unit while the dryer is in operation is sucked out with great force, making it easy to exhaust it to the outside through the duct installed in the compressor room.

The combination adsorption dryer is a heated type that is heated by an externally mounted heater. It is also a zero purge loss type energy saving device that does not consume compressed air during tower regeneration.

Insulation work had to be done to prevent heat from being lost to the outside, but since the dryer itself was so large, insulation work had to be done by climbing up and down the first and second floors using a ladder.

The company’s engineers checked the operation status of the combination adsorption dryer before the delivery.

The combination refrigerated dryer and compressed air filter were not very tall, so they were transported to the installation site using several long-axle trucks.

One combination adsorption dryer weighs about 20,000 KGS and is so large that a forklift capable of lifting special heavy loads had to be called in order to move the dryer. Since the forklift is so large, the adsorption dryer on the forklift looks small.

The loading work started in the evening when the surroundings were starting to get dark due to late delivery, but things got a little complicated during loading and the loading work could not be completed until around 1:00 a.m.

The cargo had to arrive at the installation site by the next morning, so loading work could not be postponed.

This project consists of a set of 5 combination refrigeration dryers installed on one adsorption dryer, and a total of 2 sets are scheduled to be installed and operated.

The place where this product is installed is a factory that produces steel products, which consumes a lot of compressed air. It is expected that energy savings of approximately 440 million won (about 400,000USD) will be achieved annually.
We have introduced to you the delivery history of the GCBD combination air dryer produced by our company.

Due to the rapid rise in electricity costs, production costs have risen significantly. If you are interested in energy saving, please do not hesitate to contact us. Customer satisfaction is the ultimate value we pursue.
