Refrigerated Compressed Air Dryers in GA: A Low-Cost Way To Remove Water From Compressed Air

Compressed air always contains water, coming from water vapor in the air that is sucked in by the compressor. To protect your piping, tools, and equipment, it’s best to use a compressed air dryer to dry the air. Today we’re discussing why your business might benefit from a refrigerated compressed air dryer.
Refrigerated compressed air dryers are one of the most commonly used types of air dryers in GA – they are simple in design, need very little maintenance and are relatively inexpensive.
A refrigerated compressed air dryer is the standard choice if you’re shopping for a dryer and don’t have special requirements, like an ultra-low dew point. They don’t need much or any special maintenance and if you buy a quality one, install it properly, it’s basically set it and forget it.

How Does A Compressed Air Dryer Work?

As the name implies, refrigerated air dryers work by cooling down the air like a refrigerator. The warm wet air enters the dryer, where it is cooled down to about 3 degrees Celsius. All water vapor that was in the air condenses into water, much like your window does on a cold day. The liquid water is then removed from the compressed air by a water-trap. Refrigerated air dryers work well in the GA climate.
After that, the cold, dried air is reheated back to room temperature without the moisture content.

Types Of Refrigerated Compressed Air Dryers in GA

There are basically two types of refrigerated compressed air dryers – cycling and non-cycling. The advantage of the cycling dryer is that it will increase or decrease cooling capacity according to air use. This reduces the energy used and saves you money. The non-cycling is the most common type and is extremely reliable and has the lowest maintenance costs however it uses more energy than a cycling dryer. Choosing between cycling and non-cycling depends on what your compressed air system needs.
There are a few key points to keep in mind when shopping for refrigerated compressed air dryers in GA.

  • The maximum pressure of the dryer must be the same, or higher than that of your compressor.
  •  The maximum airflow that can flow through your dryer must be higher than what your compressor can deliver.
  • Air dryers have a maximum specified inlet temperature. If this temperature is exceeded, you can either damage parts of the dryer, or the dryer just won’t have enough capacity to reach your desired dew point.
  • To avoid overheating you need to select a dryer that can handle the ambient temperatures of your compressor room. Measure the maximum temperature (in summer) in your compressor room and buy a dryer that can handle that.
