Adsorption Dryers ULTRAPAC 2000

Ultrapac 2000 Superplus / Standard Heatless Regenerated Adsorption Dryers
Ultrapac 2000 heatless desiccant dryers (midi & mini) provide clean and dry air at pressure dew points of -40 ºC and -70 ºC. Their turnkey modular design includes a preinstalled coalescing pre-filter and particulate after-filter. The desiccant is contained in easy-to-replace cartridges. The microprocessor controller alerts the operator of the optimal time to replace filter elements, keeping maintenance and operating costs at a minimum. Information regarding the operating status, fault indications and maintenance intervals can be seen on an easy-to-read text display. A capacity control adjusts the adsorption cycles to the actual water inlet load therefore saving regeneration and at the same time reducing operating costs. An Economizer provides on-line information regarding the optimum exchange point for filter elements.

The majority of air passes over a bed of hygroscopic material—such as silica gel or activated alumina—which absorbs the water vapor from the air in an adsorption drier, also known as a desiccant dryer. The hygroscopic, or desiccant, substance becomes increasingly saturated with the removed moisture as the process proceeds. As a result, most adsorption dryers have two drying vessels: one that dries the incoming compressed air and the other that is undergoing regeneration to regain its ability to dry the air once it has reached maximum saturation capacity. Before compressed air enters an adsorption drier, proper water separation and drainage methods must be in place. If you're utilizing a typical oil-lubricated compressor, make sure you have a clean, functional high-efficiency oil separating filter (0.01 micron) fitted upstream of the dryer, as well as a reliable automatic drainage system.


  1. When compared to other dryers at the time, it had a low capital cost.

  2. Although this drier will lower the dew point, it will not be able to achieve a negative pressure dew point.
  3. It has a proclivity towards polluting downstream systems.
  4. Because the energy consumption is low (only 6%), and the switching duration is long, the parts wear out slowly, improving the equipment's reliability.
  5. The final dryness of the exit air is far superior to that of the heat-free regenerated gas.


  1. Dryers that are not refrigerated have a greater initial cost.
  2. Every three to five years, desiccant beds must be replaced.
  3. It's possible that activities will necessitate the usage of purge air, diminishing total energy efficiency.
  4. If proper pre-drying filtration and draining methods are not followed, oil aerosols can cause contamination.
