Product Description 

 

Why we need compressed air dryers 

 

Untreated compressed air contains many contaminants such as water, 
compressor  oil,  pipe  scale  and  contamination  from  ambient  air.  All 

these contaminants cause excessive corrosion, erosion, freezing and 
product contamination to all components  that come  in contact with 

the  untreated  compressed  air.  A  regenerative  type  dryer  system  with  all 
recommended  filtration  will  remove  these  contaminants  to  harmless  levels. 

The  end  result  is  that  instruments  that  come  in  contact  with  the  dry 

compressed air stay clean and do not corrode, therefore lasting much longer. 
Products that may come in contact with clean dry compressed air is virtually 

unaffected, hence rejection rates are reduced. 
  

nano regenerative desiccant air dryers dry compressed air to -40°F below PDP 

(pressure dew point). The compressed air stream is passed through a desiccant 
bed,  which  removes  the  moisture  through  the  process  of  adsorption.  Twin 

towers  filled  with  the  desiccant  alternate  between  drying  and  regeneration 
either based on dew point or a fixed time cycle. nano® manufactures various 

types  of  desiccant  air/gas  dryers.  These  dryers  offer  fail-safe  design  in  the 

event of power interruption, along with tower operating status lights and the 
highest  quality  non-lubricated  air/gas  inlet  valves  that  ensure  reliable 

operation for many years to come.
