Refrigerated compressed air dryer COLDSPELL

All about refrigerant air dryer manufacturing Refrigerated 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 The principle on which the refrigerant air dryer manufacturing 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.
