What A Regenerative Dryer Is & How It Works

Types of Regenerative Dryers Slide

SAHARA Regenerative Air Dryers offer positive dew point

 

suppression to -40°F for excellent protection,

 

even under the most difficult conditions

 

of very low air line temperatures.

 

 

Unless your environmental and operating conditions are relatively uniform, moderate, and predictable enough to suggest a deliquescent type dryer, a SAHARA Regenerative dryer should be chosen to assure maximum protection for the system.

 

  • Virtually all free air contains water in the form of water vapor. We call it humidity. When air is compressed to 100 psi, the water vapor is concentrated to about 8 times normal!
  • Water vapor is no problem in compressed air until temperatures drop and condense it into droplets of water.
  • Then it combines with any other contaminants present and causes freeze-ups, leaks, and corrosion.
  • To protect your air system from damage caused by water, you must remove enough water vapor from your compressed air to bring its dew point down to a temperature lower than the compressed air will encounter at any point in the system.
  • A good air dryer is the answer.

 

 

To get clean, dry instrument quality air that means trouble-free

 

operation for your compressed air  system...

 

Choose a SAHARA Regenerative Air Dryer to fit your needs.
