The Trident Heatless Compressed Air Dryer works on the **principle of twin-tower adsorption drying** without using external heat. Moist compressed air enters one tower filled with desiccant, where the desiccant adsorbs the water vapor and delivers dry air at the outlet. At the same time, a small portion of the dried air is expanded to near-atmospheric pressure and passed through the other tower to regenerate the saturated desiccant by carrying away the absorbed moisture. The towers automatically switch roles in a timed cycle, ensuring a continuous supply of dry compressed air with minimal maintenance.
