Heat of Compression Desiccant Dryer

The KXC series heat of compression desiccant dryer is designed to remove water from compressed air in an extremely effective way, by offering pressure dew point of -40℃. It makes full use of the heat generated during air compression process for desiccant regeneration. Hence, this compressed air purification system provides dry and clean compressed air with a much lower operation cost, when compared with refrigerated air dryers and other types of desiccant air dryers.

Additionally, our heat of compression desiccant dryer delivers 1% purge loss or zero loss, which further saves energy consumption. Owing to these, this regenerative air dryer is often applied for centrifugal air compressors with large flow of 65-510m3/min.

1. Top Level PLC Controller

The heat of compression compressed air dyer adopts Siemens S7200 or S7300 PLC controller as well as 7" touch screen to realize operation status monitoring and all the other functions.

2. High Efficiency Heater Exchanger
The shell and tube heat exchanger is applied, while plate heat exchanger made of stainless steel is optional.

3. High Quality Desiccant
The fixed double beds are filled with high quality activated alumina and molecular sieve, respectively.

4. Pressure Gauges
Both towers for the desiccant dryer are outfitted with a stainless steel pressure gauge, so as to reveal pressure levels during drying and regeneration process.

5. Dew Point Display
Our desiccant air dryer uses a high precision ceramic sensor to detect the dew point, and the value is displayed on the screen. Alarming function is available to avoid too high dew point.

6. Particulate Filter
The adsorption dryer is outfitted with particulate filter to capture fine desiccant particles, so as to avoid damages to downstream equipment.

7. Large Mufflers
Large mufflers are adopted for the heat of compression desiccant dryer, so as to minimize noise level. Built-in safety relief valves are available to enhance safety.

8. Tower Insulation (Optional)
With the help of this optional design, heat won’t be released from towers, which improves regeneration efficiency. Additionally, contact barrier is supplied for safety.

9. Mounted Pre-filter and After-filter (for Selected Models)
For some models of our heat of compression desiccant dryer, pre-filter and after-filter are installed in our factory, ensuring processing results.

10. ASME Certificated Pressure Vessels (Optional)
These optional pressure vessels for our desiccant air dryers are in accordance with the requirements of ASME Section VIII, Div. 1.

11. NEMA 4 Rated Electrical Enclosure (Optional)
The NEMA 4 and IP66 rated electrical enclosure offers meticulous protections for the electrical components.
