• With compact structure and stable operation, the range of dew-point variation is ±3°C and the noise level is lower than 85dB.
• Auto circuit control and safety devices are simple and stable. After operation for 5,000-10,000 hours, the indicator light calls for renewal of corresponding parts to ensure safe handling with opti¬mal performance.
• High-quality absorbent of 4A molecular sieve .
• Aluminum alloy die-casting is adopted which offers good shape, convenience for disassembling and maintainence.
• The throughput is 0.1~0.35m3/min, working pressure is 0.39~0.98MPa and the dew-point can reach -40°C~-60°C.
• The rational tank design makes the contact time of compressed air and absorbent adjustable which reaches the required dew-point of finished compressed air.
• The amount of regenerative air is adjustable according to operating load of the dryer to make opti¬mal the velocity and time of the flowing air passing through the absorbent coat and bring the performance of the absorbent into full play.
• Rational system configuration makes it possible to remove oil and heavy pollutant in the air before it enters the drying tank.
• High-quality SMC solenoid valve and microprocessor have the function of automatic timing and task switching between the two tanks.

Heatless regenerative air dryer takes advantage of theory of Pressure Swing Adsorption. Desiccant adsorbs moisture under pressure and releases moisture, under reduced pressure. The com­pressed air after passing through inlet filter 11 enters into dry barrel 1 (or dried barrels 2) through pneumatic control valve 6 (or 5). Then it make absorption dry with desiccant bed layer, and later exist from поп-return valve 9 (or 10) to enter outlet filter 12 to be filtered, finally exist from the outlet to dry and purify air. A part of dry air (about 15%) enters dry barrel 2 (or driyd barrel 1) through current limitation pipe 8 to blow and regenerate desiccants with saturated water, then air passes through pneumatic control valves 3 (or 4) to exist out of muffler 7. Drying barrel 1, 2 work alter­nately to regenerate.
