Treating Compressed Air: What You Should Know


Air treatment equipment includes such machines as thermal mass dryers, air receivers, and breathing air equipment. These forms of equipment complement the use of compressed air in industrial and commercial environments. Here is some advice on EU standards.

What Is a Receiver Tank?

One of the essential components in a compressed air system is a receiver tank. This tank serves as a reservoir when compressed air is needed during peak times. The receiver removes water from the system by giving the air a chance to cool. It also reduces pulsation in the compressor system, which is caused by a cyclic process downstream or reciprocation.

A Well-Used Component

An air receiver can serve one of the various purposes. It not only reduces the wear and tear on a compression unit but it also lowers energy consumption. Thousands of facilities use air receivers, which vary in size, colour, or model type.

As noted, you can liken an air receiver to a water reservoir as it balances out the demand on a compressor system and compensates for peak demands. Receiver tanks feature a pressure gauge and pressure relief valve. The relief valve should be set at 10% over the working pressure for the compressor to operate efficiently.

The Presence of Water

It is also helpful, if not essential, to install a drain on the receiver tank to get rid of any water from the system. Usually, an air dryer or air filtration in Birmingham is a noted choice. Anyone who uses compressed air will see water in the air distribution system after a time. This can either be considered an annoyance or a serious complaint.

The idea is to remove the water from the compressed air by discovering its origin and the proper methods of removal. Some vapour or liquid removal processes, such as air drying, may be considered. Therefore, it is essential to define what equipment needs to be used to get rid of the problem.

Relative Humidity

A compressor draws in the air that contains water. This water is known as a gas and is referred to as humidity. The relative humidity represents the amount of water vapour that is held in the air due to the temperature. Usually, atmospheric air contains about half of its water vapour for a given temperature. The proportion denoted for the optimum holding capacity is defined as the relative humidity.

The Dew Point Reading

When air with a given relative humidity is controlled, it reaches a temperature reading where it is saturated. Therefore, the relative humidity is 100% when the air is fully saturated. The air contains all the vapour that it can hold. The temperature reading when the air reaches 100% relative humidity is called the dew point. When air is cooled beyond the dew point, it leads to condensation.

You can cool saturated the compressed air in one of various ways. For example, you can expose the air lines from a compressor to cooler temperatures outdoors. You can also use pressure regulators, expansion vessels, vortex tubes, and receiving tanks. These items are added to reduce the pressure. Process equipment such as dryers and after-coolers are also used. Whatever measure you take, it will lengthen and optimise the use of your compressor equipment.
