- Condensation is the moisture that drops out of an air flow as it cools.
- The condensation in a compressed air system is a constant threat to cause expensive problems.
- Safe and efficient removal is necessary.
Moisture washes lubrication from air tools and production equipment causing downtime and maintenance.
- An inconsistent supply of dry air causes production quality problems.
- Excessive rust and scale often forms in the air distribution system.
- Water can back up into the compressor and wreck the machinery.
- Air dryers can become overloaded.
- In-line filters can be destroyed. The problems get worse if you operate lubricated reciprocating or oil flooded rotary screw compressors – which is just about everyone.
- Compressor oil makes its way into the distribution system with the compressed air. The mixture of oil, water, dirt and heat tends to build up a sludge that will ultimately jam or clog production equipment, air tools and drains.
The situation is further complicated by climate and seasonal weather changes. This is because the amount of condensation generated will change according to changes in the temperature and the relative humidity of the inlet air.
The typical compressed air system is designed to remove condensation at strategic locations. This means there are drains at the after cooler separator, receiver tank, air dryer, in-line filters and at drain points in the piping.
