Air Dryer for Dental Air Compressor
|Air Dryer For AC11/AC12/AC31/AC32||AC51|
Compact Heatless Regenerative Air Dryers:
The requirement for clean, dry compressed air for today's manufacturing and processing methods is more critical than ever. Moisture and particulate matter are found in all compressed air systems. These contaminants cause rust and corrosion damaging and increasing downtime of pneumatic tools, controls, and instrumentation. When applications require better dew points than can be achieved with refrigerated air dryers (35° F to 39° F) a heatless regenerative desiccant dryer should be utilized. -40° F to -100° F (-40° C to -73° C). At one time, compressed air dryers were luxuries. Today, as maintenance costs continue to rise, and the need for increased productivity grows, they're a necessity in nearly every process where compressed air is used. The HY air dryer, together with its associated filters, is a key part of a well-engineered compressed air system. HY, an industry leader in the design and manufacture of innovative compressed air products, has developed the GXW Series -40° F to -100° F (-40° C to -73° C) pressure dew point Heatless Regenerative Desiccant Dryer to meet the ever-increasing demand for efficient and economical ultra dry compressed air. Our Compact Regenerative Pressure Swing Heatless Air Dryers, together with a broad range of high-efficiency filters, can provide total air treatment with outstanding reliability and performance for your compressed air applications.

The heatless air dryers utilize two symmetrical desiccant towers. The wet air enters the dryer and flows through one of the towers where nearly all the water vapor is adsorbed. In the flow schematics shown below, the right tower is being regenerated while the left tower is drying the wet inlet air. Inlet air flow direction is controlled by the solenoid valves. As shown below, Valve B is open and valve A is closed, which allows the inlet shuttle valve to direct the air to the left tower. A portion of the dry air is allowed to flow through an purge flow adjusting valve into the right tower. The dry air flowing through the adjusting valve expands to nearly atmospheric pressure, which dries the purge air still more. This very dry air extracts the water from the desiccant as it flows through the right tower and out the solenoid valve exhaust port. The adjusting valve are fixed and are sized by the factory, based on flow and pressure. A elecrical timer controls the cycling of the solenoid valves. After a set period of time, the procedure is reversed. The wet left tower is being regenerated, while the right tower is drying the wet inlet air. During each cycle, the desiccant towers are either drying the wet inlet air or being reactivated with dry air from the drying tower. The total cycle time may be choosed by one, two, five or ten minutes.
