A refrigerated air dryer is a device that removes moisture present in compressed air.
The temperature of the compressed air discharged from the air compressor is higher than the ambient temperature due to the heat of compression.
Refrigerated air dryers exchange heat with this high-temperature compressed air with cold refrigerant, instantly dropping the temperature. During this process, a large amount of condensate is generated.
This condensate is discharged to the outside through the automatic condensate discharge device inside the dryer.
About 3 months ago, we received an order for 6 sets of refrigerated air dryers (air-cooled) corresponding to a 600HP air compressor through our U.S. agency.
The compressed air processing flow rate per unit of the dryer is 85Nm3/min.
This dryer is scheduled to be delivered to Brazil’s largest steel manufacturing company, and it is said that it will be supplied as a replacement for the dryer used previously as it becomes obsolete.
Since it was supplied as a replacement for the old air dryers, consumers wanted to use the existing piping as is.
However, since our air dryers, which use a micro channel aluminum heat exchanger, have fixed inlet and outlet positions, it was not easy to accommodate customer requests.
We presented a solution to this problem to our client by additionally supplying INLET PIPE, OUTLET PIPE, and FLEXIBEL PIPE.
This is to replace the existing air dryers without additional piping work such as removing or changing the existing piping.
The air dryers are designed with a ventilation fan located at the top of the units so that the hot air inside the air dryers can escape smoothly through the top of the units.
If a ventilation duct is installed at the top of the dryer, the hot air generated when the air dryers is running can be discharged to the outside without being stagnant in the compressor room, so the air dryers can continue to operate stably.
This is the appearance of the refrigerated air dryer HYD-600NS models that have been manufactured and tested.
There is a touch screen control panel attached to the upper right side of the front of the dryer.
Users can check information such as dew point, compressed air inlet temperature, ambient temperature, refrigerant return temperature, and refrigerant condensation pressure through the corresponding control panel.
You can use the touch button on this panel to check whether the power phase is properly connected.
In the case of an air-cooled dryer, the fan starts when you touch the PHASE CHECK (AIR) button at the bottom right, and if the fan rotates counterclockwise, you can determine that it is in reverse phase.
In the case of a water-cooled dryer, if the refrigerant low pressure gauge does not decrease by touching the PHASE CHECK (WATER) button, it can be judged that it is in reverse phase.
We hang an AC CLAMP METER on the live wire to check whether the current flows smoothly when the dryer is in operation.
The dryer is equipped with a drain trap that automatically discharges condensate to the outside of the dryer.
This model uses a sensor-type drain trap that automatically opens the port gate by detecting the height of the condensate level when condensate collects above a certain level.
If you do not properly check for reverse phase during test operation after installing an air dryer, it may suffer serious damage.
In order to prevent such accidents, we put a sticker on the front of our air dryers to alert customers to the fact that the units must be checked for reverse phase before operation.
You can check the current operating status of the dryer through the pressure gauges attached to the front right side of the dryer.
You can check the pressure of the compressed air entering the dryer inlet through the pressure gauge at the top of the photo.
You can check the pressure of the compressed air discharged out of the dryer through the middle pressure gauge in the photo.
You can check the pressure at which the refrigerant is returned to the refrigeration compressor through the pressure gauge at the bottom of the photo.
We use eco-friendly refrigerants and cares about the Earth’s environment.
In the dryer’s secondary heat exchanger, the hot air on the inlet side and the cold air on the outlet side are exchanged and reheated to prevent water condensation in the dryer outlet pipe.
Some consumers believe that the lower the air temperature at the outlet of the dryer, the better the dryer is, but this can be said to be an illusion.
The dryer in question does not have a reheating function or has a low reheating ability.
Drain outlet ports are located at the bottom right of the product through which condensate can drain out of the dryer, and a cable grand is provided to easily connect the main power cable.
Users can easily download the product’s instruction manual, data sheets, drawings, etc. from our company website anytime, anywhere through the QR code attached to the product.
The wrapped products are transported to a specialized export packaging company for export wood packaging.
6 sets of air dryers, INLET/OUTLET connection pipes, and FEXIBLE PIPE have been packaged for export.
A skilled forklift operator is loading packed air dryers one by one into a 40-foot High Cube Dry container.
The truck loaded with all dryers is leaving for a seaport in Busan to be loaded onto a ship bound for Brazil.
