Compressed air is extensively used in industries. Humidity is the moisture present in the atmospheric air that can be found in the compressed air distribution systems in the form of vapor. If left unattended the moisture that is present in compressed air may follow the air flow all the way to the final product and causes serious damage to the distribution network. Here comes the need Humidity control systems.
A traditional humidity control systems comprises of compression, refrigerating, storing and circulation equipment. Compressed air dryers are used for the removal of residual water and other contaminants from compressed air.The air can be dried in single or multiple stages to prevent tool decomposition and other problems associated with water. The usage of compressed air dryers comprise creating favorable climatic conditions, the level air dryness needed apart from cost and consistency.
Moisture can cost you a lot of money on maintenance of your equipment. Humid air is not favorable for a clean, efficient, smooth-running system.
Understanding how water goes in a compressed air system will help exemplify the extent of the problem that can be caused by humidity. When air is compressed the moisture and dirt present in the nearby atmosphere are also compressed with it resulting in a high concentration of moisture and impurities in the receiver. For example, at 75°F ambient temperature and 75 percent relative humidity, a 100 scfm compressor will take in the equal of 18 gallons of water, as vapor in a day.
The raising temperature of the compressed air proliferations the problem. The greater the air temperature, the higher is its ability for holding water vapors. Contrarily, as the air temperature is decreased, its ability for holding water vapor is also decreased. An after -cooler positioned instantaneously after the compressor will allow some of the moisture to be released as condensate, but it wona€ t cool the air sufficiently to remove enough remaining water vapor to protect the entire system. Airline filters installed downstream will to a certain extend remove solid impurities and water vapour, but are not able to remove water vapor. As the air cools downstream the water is released it will expose your systems to a number of moisture related problems. It can affect the operational efficiency and may results in premature failure of equipment that may also disrupt your production. Air dryers are very much essential for the efficient operation of compressed air system.
