Heatless Purge Desiccant Compress Air Dryer

Technical flow:

A,B： Absorb tower
1、2、3、4： Switch valve
5： Silencer
6、7： Check valve
8： Throttle
9： Program controller

Product character:

1. Consistent outlet pressure dew points:
A、Rationalizing designed tower, ensure 4.8 second contact, enough to dry saturated air at the dryer inlet to the desired dew point.
B、30% extra desiccant provide to compensate for natural bed aging, ensure top performance of desiccant bed.
C、Large flow diffusers ensure even flow distribution through bed, eliminates channeling.

2. Minimum purge air use, less than 12%, the lowest in the Industry.
A、Excellent designing tower, saves 95% of the heat of adsorption, stored heat maintains purge air temperature during regeneration, maximizing the purge air’s ability to carry off moisture, minimizing the amount of purge air required.
B、Drying and purging in counter flow arrangement, energy not wasted when wet air travels through dry desiccant.
C、Ability to match purging air travels through dry desiccant.

3. Long desiccant life.
A、Suitable tower sized make the air velocity through the bed won’t fluidize desiccant, making good use of the desiccant.
B、Rationalizing system, remove oil and heavy contaminants before flow into the tower, protects bed from contamination. Using butterfly valve and reliable program controller which can be auto timing and auto switching, works stable and reliable, unacted on electric net, pressure and electric filed. Scientifically designed switch time ensuring the air pressure being stable, running without waving. Non basement, easy to install.
