HRDS series Heated Regenerative Desiccant Air Dryer utilizes the principle of pressure swing adsorption and a low heated regeneration method to dry and dehumidify the compressed air, it is similar to HRD series heatless desiccant dryer, but it has a low capacity heater. HRDS Desiccant Air Dryer is an advanced device that uses compressed pressure adsorption principle to dry compressed air through a high absorption alumina or molecular sieve. Usually allows compressed air to dry to a dew point of -40 ℃ to -70 ℃. The structure is a double tower type, one is adsorbed and the other is regenerated. The cycle is 240 minutes and is switched every 60 minutes. The duty cycle consists of a drying process in which the airflow rises and a regeneration process in which the airflow falls. During regeneration, a part (about 6%) of the dried compressed air is taken out, thawed and expanded by the orifice plate, and then heated into the heater. The heated high-temperature gas enters the column to remove the water adsorbed in the desiccant. Suck out. When the regeneration is switched to dry, the moisture in the compressed air is adsorbed on the desiccant, so that the cycle works to achieve the drying air.
Features
1.The large-capacity desiccant bed ensures sufficient drying time, and can fully absorb water, an additional 30% desiccant can compensate for the natural aging and ensure the desiccant life exceeds 3 ~5 years.
2.The tower design can store 98% of the adsorption heat, maintain high temperature of the regeneration gas, and improve regeneration capacity, dry and regenerate the reverse flow, so that the wet air does not flow through the dry adsorbent.
3.The filling amount of the adsorbent is extremely abundant. The large-capacity desiccant bed ensures sufficient contact time between the air and the desiccant, so that the desiccant can fully absorb the water and reach a stable outlet dew point. Ensure the stability of the outlet air dew point and remove the water.
4.Advanced PLC controller with automatic timing, automatic switching, working time setting, fault alarm and other functions; dynamic display of operating status.
5.Regenerative air consumption can be adjusted, with energy saving and dew point adjustment.
6.High-quality muffler effectively reduces noise and has pressure protection function to improve product safety.
7.Multi-cycle heating device, high heating efficiency, low gas consumption, maximum energy consumption
8.Automatic alarm device, intake air temperature too high alarm, intake pressure too low alarm, heater temperature too high alarm.
9.Scientific and reasonable structural design, novel appearance, elegant appearance, long-term high efficiency, stable performance, convenient operation, maintenance and maintenance, easy installation.
