AIR / GAS DRYING UNIT :

WHY DO YOU NEED DRY AIR ?

.
Atmospheric Air is sucked by air Compressor which basically contains water vapour & dust. Besides, in lubricated type Air Compressors, oil is present in the air compression chamber, traces of which are present, in compressed air in Liquid / Vapour form, which condenses into a heavy gummy oil varnish.

Condensed moisture together with dust and oil in compressed air leads to emulsion formation causing following troubles:

  Formation of rust & scale, clogging orificies, resulting in malfunctioning of tools, 
            controls & instruments.

  Freezing in air lines causes malfunctions & damages to process Equipments.

  Increased resistance to flow.

  By corrosion of air or gas the instruments can give false reading disrupting 
            product quality.

  Rust & scale contaminates products when compressed air is used in mixing 
           and processing.

  Bubbling effect in spray painted / Powder coated items.

  Sluggish operation of pneumatic equipments.

Operation Of Ideal Compressed Air Drying System :

If the temperature of the compressed air is more then 40o C then it is necessary to provide AFTER COOLER which should ensure the outlet temperature of 400C.

During this cooling process, some moisture condenses which is removed our from prefilter.

If the Air compressor is non-lubricated type then there is no need of Activated Carbon Filter, but if the Air Compressor is lubricated type them Activated Carbon Filter before Air Dryer is must. The characteristic of Activated Carbon is to remove the oil vapour totally from the compressed air. This ensure the full life of the desiccant in Air Dryer.

The HEATLESS type Air Dryer is the simplest & Economical Air Dryer with Activated Alumina Molecular Sieves  as the desiccant. The twin Absorbers filled with these desiccant is assembled with 3-way, 2-way, control  valves  and  interconnected  pipings. The  unit follows the Drying sequence of 10 minutes.  Here one absorber is under drying  cycle for 5 minutes and simultaneously the other absorber under goes for
regeneration  and  equalization  process  for  (4 + 1)  5  minutes  respectively. The  changeover  of  the absorber takes place with the help of sequence timer. The moistured air  and regenerative air is drained out  through  the  individual silencer of the absorbers provided at the bottom hence super Dry Air  comes from the top of the Absorber & is taken to your process for your applications.

During this cooling process, some moisture condenses which is removed our from prefilter.
