Application of the principle of natural gas dryer temperature swing adsorption, pressure swing adsorption (work) at room temperature and high water vapor partial; at higher temperatures, low water vapor partial pressure parse (regeneration). 1. Overall skid mounted equipment, compact layout. 2. Adsorbent loading capacity, long life adsorbent. 3. Closed recycling, natural gas consumption is not another four. Control panel features a text display, good maneuverability. 5. SCR electric heater temperature controller to achieve automatic control and energy saving. 6. Full-proof design, safe and reliable. 7. High efficiency filter, the elimination of water, protection of system stability.
