Why dry compressed air? Contamination reduces efficiency         The air we breathe contains contamination in the form of water vapour and airbonrne particles.During the compression process an air compressor concentrates these contaminants and depending on the design and age will even add to the contamination in the form of oil carry over. Modern air compressors generally have built in aftercoolers that reduce the discharge temperature of the compressed air and with the help of water

Ingersoll Rand's Air Quality Solutions.Introduction.Compression the hot dryer is a pair tower type,dryer design.Compression the renewable hot dryer is the most efficient dryer.it can naturally recover the quantity of hot generated by the process of compressor.this "free"heat as used to the air drying process, in the provision of dry air at the same time,almost did not spend any energy.
