Why compressed air should be treated
Compressed air is one of the most important industrial energy carriers, therefore investments that enable its more efficient use are of great importance. It concerns both the ability to maintain sufficient amounts of compressed air and its cleanness. It is important that compressed air is dry and clean.
Atmospheric air, that enters the compressor, contains such contaminants as solid, and water particles. The compressor itself is also a source of contaminants (oil, wear products). Thus following compression, what enters the compressed air network is air containing water vapour, dusts, oil vapour and small amounts of aggressive gases.
Heat is produced during compression, therefore compressed air leaving the compressor is so hot that, in combination with ambient conditions, condensate is precipitated causing compressed air installation and equipment to corrode.
Air treatment consists in cooling, drying and removing dust and oil particles.
In order to achieve that, the following different solutions and devices, selected to satisfy individual clients’ needs, are applied:
- refrigerant dryers,
- adsorption dryers,
- air filters,
- centrifugal separators,
- oil-water separators,
- automatic condensate drains.
Advantages of applying compressed air treatment devices
- longer pneumatic equipment life-span
- undisrupted technological process course
- environmental protection
- savings resulting from a decrease in the amount of oil condensate intended for disposal
- water condensate carried straight to the sewage
- compressed air quality guaranteed in accordance with the ISO 8573.1 standard
- reliable compressed air equipment work
- cost reduction involving machines maintenance and repairs
- limited corrosion of compressed air installation
- elimination of unexpected production stoppages
- lower costs of compressed air
