Refregirator Air Dryer



WHY IS COMPRESSED AIR PROCESSED?

Compressed air is an essential form of driving and process energy in all fields of industrial and production manufacturing. Compressed air must be dry, free of oil and clean to avoid expensive production breakdowns.

Compressed air is produced by compressing air which is sucked into the compressor. This usually contains pollutants, dirt particles and always moisture in the form of water vapour, which condenses spontaneously in the compressed air and can then lead to disruptions in operations and thereby to substantial but avoidable costs.


HOW DOES A DRYER WORK?

To process the compressed air, it is fed into the refrigeration compressed air dryer and is pre-cooled in an air/air heat exchanger. This pre-cooling is conducted in counter-flow with the expelled, cooled compressed air and therefore operates completely without additional energy.


Further cooling to the pressure dewpoint is conducted in a refrigerant/air heat exchanger cooled by a refrigerant cycle. Throughout the entire cooling process, moisture is precipitated from the compressed air as condensate and is automatically drained. Before being expelled the processed compressed air is re-heated in the air/air heat exchanger by means of the entering compressed air.

    The reliability of compressed air filtration is paramount to the on going fight against problems caused through contamination entering the air system. Contamination in the form of dirt, oil and water can lead to:

  • Pipe scale and corrosion within pressure vessels
  • Damage to production equipment, air motors, air tools, valves and cylinders
  • Premature & unplanned desiccant replacement for adsorption dryers
  • Spoiled product

    • The AIRTECH filtration range offers various products and grades of filtration to provide peace of mind whatever the air quality requirement.Compressed air contamination will ultimately lead to :

  • Inefficient production processes
  • Spoiled, damaged or reworked products
