As the name suggests, a refrigerated air dryer operates by cooling compressed air just above the freezing temperature. By doing so, the air dryer condenses the moisture in the compressed air and turns it into liquid.
This is then collected and drained. Meanwhile, the air is reheated with the help of a heat exchanger. Now that the air is reheated to the room temperature, there is no risk of moisture accumulation within the downstream pipes. Here is a breakdown of the steps involved in the workings of a refrigerated air dryer.
The capacity of the refrigerated air dryer must be on par with that of the compressor. It is generally recommended to source a refrigerated air dryer that exceeds your compressor’s maximum output. Failing to do so can have detrimental effects, such as inefficient moisture removal and pressure drop.
The desired dryness of the air depends on the intended application. You must source a refrigerated air dryer with a pressure dew point that ensures appropriate moisture elimination.
When sourcing refrigerated air dryers, it is essential to consider the brand’s reputation. When you spend top dollars on sourcing something as important as a dryer, you want it to last for many years. Doing business with SL Engineering guarantees durability and optimal performance.
