subject: Dealing With Condensation In Compressor Equipment [print this page] Compressed air has many industrial applications. The use of compressor equipment can, however, create its own difficulties. One of the problems that the users of compressed air must deal with is condensation that occurs within the equipment.
When air is compressed, contaminants within the air are concentrated, including water vapor. Condensation occurs when the elements that have been compressed cool as they travel away from the compressor. The end result can be freezing of the air lines, corrosion in the pipes and, ultimately, malfunctioning of the equipment. Additionally, moisture can reduce the effectiveness of lubrication that might be used within the equipment. There are a number of things operators of compressors can do to deal with this nuisance.
To reduce condensation, the operator should always take drops off the top of main line, which will make for easier draining of the system. Main lines should always be pitched toward a drain or tank. Any valve that is used should be installed ahead of the drain, which will also enhance maintenance. The use of "drip legs" can be beneficial in collecting moisture that develops within air pipes, and should always be placed in the low points of an air line. They are also needed in pipes that run from outdoors into an indoor setting because of differences in the atmosphere, with a warmer ambient temperature and a higher relative humidity producing greater levels of condensation.
Stainless steel is the best material for use in compressors that do not rely upon lubrication. Oil can actually reduce corrosion in compressor systems using traditional black iron pipes. However, when oil becomes contaminated with moisture, the substance is considered a hazardous material and requires proper disposal.
A compressed air dryer is a piece of equipment that can be used to reduce condensation.
Additionally, different types of drains are available to eliminate the moisture that appears. The manual drain is the basic type, although other drains are operated by floats or timers and will automatically eliminate condensation. An elaborate drain has an electronic sensor to evaluate the amount of condensation and remove it when needed.
Operators of compressor equipment should never underestimate the possibility of condensation, and take the proper steps needed to reduce the risk.
Dealing with condensates in your air compressor system is an essential aspect to maintaining the long life of your machine. Be sure to always properly dispose of these condensates in order to ensure your air compressor runs at maximum efficiency.
