How does an air dryer work?

Although we frequently consider water to be vital to life, it may really be quite harmful to manufacturing. Water vapour is concentrated during the air compression process in an air compressor setup. This extra water can cause several operational issues and production difficulties if it is allowed to accumulate.

Process air is separated from water vapour and cooled using an industrial compressed air dryer so that the air may be compressed effectively. This procedure is required to avoid production setbacks including frozen exterior air lines, hazardous piping and equipment corrosion, and broken pneumatic process control devices.

For seamless manufacturing, Trident Pneumatics offers a selection of compressed air dryer unit. Regenerative, breathing air system, membrane, and chilled cycling and non-cycling are all part of our portfolio. Air dryers are necessary to keep your air compressor setup dry and stop rust from forming. The various compressed air dryers are examined in this article along with some of their applications.

Refrigerated Air Dryers: Refrigerated air dryers are frequently used in industrial settings since they are simple to maintain, inexpensive, and don't need many particular conditions. The industrial refrigerated air drier operates in a manner akin to that of a home refrigerator or air conditioner: Warm, humid air is drawn into the air dryer.

In a refrigeration system, it is quickly chilled to a temperature just above freezing.

Condensed water is created from the water vapour.

Water is trapped and then released through discharge lines.

In a condenser, the hot, gaseous refrigerant is cooled and replenished.

After that, room temperature dry air is heated and fed through an outlet.

Refrigerated air dryer price work better for routine industrial operations rather than crucial procedures that could need highly dry air.

Desiccant-Type Air Dryers: A desiccant is used in these dryers to collect water vapour from the air stream. In this situation, the moisture sticks to the desiccant and gathers in the pores of the desiccant beads. These dryers are ideal for colder climates or in businesses that require extremely dry air since they can achieve a very low dew point.

Desiccant-type air dryers typically feature a twin tower construction; however a single tower setup is workable. The first tower is used to dry the air, and the second tower regenerates consumed desiccant. Heat, dry air purging, or a combination of the two are used to drive off moisture. Purge air is used in the dry air process to remove moisture, which can make up to 18% of the overall air flow. The desiccant dryer's dew point value is roughly 40°F, although it may be lowered to -100°F. With identical dew points, the heated process has a heater in the circuit. Approximately 8% of the air leaving the drying tower is redirected via valves and sent through the heater. The captured moisture is then released to the outside as the hot, dry air is passed through the regenerating tower. The price plays a significant role in selecting a desiccant-type air dryer. A heated drier might regenerate with roughly half of the compressed air, but they take a lot of electricity. A heatless drier can save a lot of electricity. You should keep in mind the price of routine desiccant bed replacements with these dryers, which typically need to be done every 3-5 years.

Membrane Air Dryers: A specially created, permeable membrane that permits water vapour to pass across it is a component of a membrane air dryer. To reach the necessary pressure points, a substantial purge air loss is needed. The membrane in this method can become clogged with oil and other impurities, but it has inexpensive installation and operation costs and no moving parts. Low-volume operations, outdoor installations, or hazardous settings are where this sort of dryer excels. It's difficult to choose the right air drier for your air compressor setup, but you don't have to go through it alone. The compressed air experts at Trident have the expertise and experience to guide you through every step of maximising the effectiveness of your air compressor system.
