Why do compressed air systems need to be dry?


 

 

There are many benefits to adding an air dryer to the application. The initial cost of adding dryers is quickly offset by the positive impact they have on your application.

 

Eliminating water threats

All compressed air systems produce water.

The atmosphere contains water vapor, and when the air or gas used in the compressor system cools to a temperature below its saturation point, the water vapor begins to condense into liquid water.

Moisture in compressed air is troublesome in the manufacturing process. The accumulation of excess moisture can cause problems in the operation of pneumatic systems, solenoid valves, and pneumatic motors, which may be bad news for the process or the actual products produced.

The presence of water can:

Remove important lubricants to prevent increased wear of moving parts, which can cause rust

Discoloration of paint or making it difficult for paint to adhere

Causes rust, scaling or blockage of openings leading to damage to pneumatic controls

Freeze the inside of the control line, causing the control to operate incorrectly

Causes corrosion in instruments that use air, resulting in inaccurate readings, thereby completely interrupting or stopping the production process

 

Create pollution-free factory air

By adding a dryer to the compressed air system, your operating costs will be reduced. The use of clean, dry compressed air prevents dust, water and oil from depositing on pipes and fittings.

The accumulation of contaminants in the pipeline will cause more pressure drop, which means that the performance efficiency of the equipment will be reduced.

Clogging of valves, fittings and instrument control lines by liquid water can cause rust and corrosion. The same problem of plugging is more likely to occur if the water in the line freezes.

 

Protection valve and cylinder

Dirty, humid and oily air deposits can form silt and begin to block the pneumatic cylinder, resulting in frequent maintenance of seals and bearings. Operation slows down, which may eventually lead to downtime.

If there is moisture in the system, it will reduce the moisture in the oil required for the cylinder head and piston rod to work properly. It also corrodes the walls and slows down the response speed, which leads to a decrease in production efficiency.

If moisture flows through, the rubber diaphragm and valve may harden or even crack. It is also possible to pit spools and pistons. None of this is good for a smoothly running production process.

Moisture slows down the cylinder and may even cause the cylinder to jam, which can mean a lot of downtime.

By keeping the compressed air supply clean and dry, these problems can be completely avoided.

 

Extend the service life of pneumatic tools

Pneumatic tools require clean, dry air at the proper pressure for optimal performance. Dirty and humid air can cause problems in the operation of compressed air powered tools.

Excessively worn parts will start to stick, clog and rust, causing slow operation. This means that you will spend money on repairs and replacement parts.

Liquid water will wash away the oil needed to keep the tool working properly.

Clogged lines and parts will cause the pressure to drop and the tool will lose efficiency.

By eliminating water in the pipeline of pneumatic tools, they will exert the highest efficiency and greatly extend the service life of the tool.

 

Create the best instrument air

Moisture and particles caused by corrosion can damage transmitters, relays, integrators, converters, recorders, indicators and meters.

Even small amounts of moisture passing through these sensitive systems can cause serious problems with process control and failure.

Instruments and pneumatic controllers must have clean and dry air to operate effectively, especially in applications such as textile plants, chemical and petrochemical plants, power plants and most general manufacturing plants.

Instrument Society of AmericaInISA-S7.3The quality criteria for instrument air are outlined in. A copy of this list can be purchased from their website or, to save time and money, you can callISCAn expert in the sales department. They will be happy to help you determine the air quality required for the pneumatic process.

 

Maintaining the quality of the final product

If the compressed air pipes used in food production contain large amounts of moisture and oil, it may contaminate the final product and destroy it. No one wants to make a defective end product!

 

Controlling the moisture in the line air can cause water stains in paint, wrong mixtures in wine, and wrong mixtures of ingredients in food.

In the paper production process, air is used to place or move the paper, and water will make the paper dirty or make the ink not stick to the page.

For these processes, it is important to maintain clean and dry air to prevent damage to the final product and loss of profits.
