Compressed air dryer
Refrigerated Air Dryer is used to dry compressed air that contains water to provide complete protection to pipes, tools and equipment. Its simple design and low maintenance cost make it ideal to be used in different commercial and industrial applications. This works by cooling down the air to about 3 degrees Celsius that enters the dryer in warm form. The water vapor present into the warm air is condensed into water. The liquid water is eradicated by a water-trap. Once the air is cooled and dried, it is re-heated to room temperature.
The cooling through this dryer is carried-out in the same process as it is done by freezer and fridge. The liquid refrigerant is evaporated for cooling down the warm compressed air in a different circuit. The air is cooled and refrigerant is warmed and compressed by a compressor and cooled in the condenser.
Types of Refrigerated Air Dryers:
They are available in two types, one is cycling and other is non-cycling. The prime advantage of this cycling dryer is its ability to increase or decrease the cooling capacity as per the air use. This kind of refrigerator reduces the consumption of energy. The non-cycling type of dryer is extremely reliable available with lowest maintenance costs.
Points To Keep In Mind Before Buying Refrigerated Air Dryers:
- Maximum pressure should be the same, or higher than the compressor.
- Maximum flow should be higher than the flow of compressor.
- Dryers should have maximum specified inlet temperature
- Maximum outside temperature
When saturated compressed air passes through the air heat exchanger, it gets cooled by the outgoing cold dry air. This effective pre cooler is designed to lower down the temperature considerably. It uses smaller & reasonable refrigeration system. After getting cooled, this relatively low temperature compressed air comes in Refrigerant heat exchanger and gets cooled down to +3ÃÂ°C.
This temperature helps the moisture to condense into liquid form and also gets separated from the compressed air using moisture separator. This air is then discharged to drain port with the aid of automatic drain valve.
The cold dry compressed air returns to Air to Air Heat exchanger for again gaining temperature with the aid of incoming warm air. This dry air is now ready to use for varied process air, instrumentation and other applications.
