Refrigerated air dryer systems and heatless are two broad categories of air dryers available these days. Talking about air dryers remains incomplete without mentioning the concept of dew point temperature. It is the unit used to measure the dryness of compressed air. At this temperature, the moisture present in the compressed air in vapour form condenses to form liquid. Similarly, pressure dew point temperature and atmospheric dew point temperature are the two distinct temperatures of compressed air when under any kind of pressure and atmospheric pressure respectively. When we talk about the most advanced and cheapest mode of drying compressed air, refrigerated air dryers are quintessential.

Operation Refrigeration air dryer
The principle on which the Refrigeration air dryer manufacturers takes place and subsequently works is that cooling of compressed air cause condensation of water that is carried by the compressed air in vapour form. The cooling takes place in two stages in the refrigerated type of air dryer. The compressed air enters the refrigerated type of air dryer at about 40 degree Celsius. It enters the pre-cooler firstly wherein the outgoing cool-dry air cools the incoming hot-wet air. The outgoing cool-dry air on the other hand is heated upto an operating temperature of about 28-32 degree Celsius. This partially cooled hot-wet air then enters the evaporator wherein it is chilled down to a temperature of about 2-8 degree Celsius. The chilling down of the hot-wet air condenses the moisture bored by the air in vapour form. Next, the chilled air bearing condensed moisture is subjected into the moisture separator, which is a mechanical equipment that helps separate the condensed moisture from the air by mechanical activity. The moisture separator drains out the moisture via an automatic drain valve. This cool-dry air is then passed through the pre-cooler as mentioned above. In a nutshell, this process produces dry air which can be obtained through the outlet. This dry air is of a pressure dew point temperature of about 4 degree Celsius or as required but above 2 degree Celsius. The amount of power consumed by drying air in the refrigerated air dryers is approximately 5.0 kwh for 1000 cubic feet per minute of air.
What Trident Offers
An ideal solution for clean and compressed dry air is provided by Trident , one of the experts among the Refrigerated air dryer Manufacturers. Extensive design strategies and prototype testing culminates in Trident’s amazing products that offer a constant dew point of +3 degree Celsius. Also, the HX series of Trident offers a very low running cost unlike the other air dryers. Some exclusive features of these products are:-
The cold dry compressed air passes back through the secondary side of the Air to Air heat exchanger where it is reheated by the incoming warm air. Reheating the outgoing compressed air increases the volume of the air enabling it to do more work and it also prevents downstream pipe sweating. Trident heat exchanger has no extended surfaces or sharp corners that collect dust, dirt or oil residue. Their self cleaning smooth surface tube in shell and tube design will maintain the same heat transfer efficiency through out the dryer’s life. Any dust, dirt or oil will be washed off from the air system along with the condensed moisture at the De-mister.
