PDC Machines Argon Compressor

What is Argon?

Argon is a chemical element with the symbol Ar and atomic number 18. It belongs to the noble gas group on the periodic table, which also includes helium, neon, krypton, xenon, and radon. Argon is denser than air, and its density increases with decreasing temperature.

At room temperature, argon exists as a colorless, odorless, and tasteless gas. Argon has a boiling point of -185.9°C (-302.6°F) and a melting point of -189.3°C (-308.7°F).

Applications of Argon:

Welding: Argon is widely used as a shielding gas in welding processes. It protects the weld area from atmospheric gases like oxygen and nitrogen, preventing oxidation and ensuring high-quality welds.

Lighting: Argon is used in various types of lighting, including fluorescent lamps and neon signs. When an electric current is passed through argon gas, it emits a distinctive color, often blue or violet.

Laboratory and Scientific Applications: Argon is used in laboratories for its inert properties. It is often employed in gas chromatography and other analytical techniques where a non-reactive atmosphere is needed.

Electronics: In the manufacturing of semiconductors and other electronic components, argon is used as a process gas or in plasma technology.

Medical Applications: Argon is sometimes used in medical procedures. For example, argon laser therapy is employed in ophthalmology for eye surgeries.

Metallurgy: In the production of specialty metals such as titanium and zirconium, argon is used as a protective atmosphere during certain processes.

Food and Beverage Industry: In the food industry, argon can be used as a preservative gas to displace oxygen and extend the shelf life of certain products.

Geochronology: Argon-argon dating is a radiometric dating method used to determine the age of rocks and minerals. It relies on the radioactive decay of potassium-40 to argon-40.

Gas Atmosphere for Analytical Instruments: In analytical instruments like mass spectrometers and nuclear magnetic resonance (NMR) spectrometers, argon is used as a carrier gas or in the sample environment.

The diverse range of applications stems from argon’s inert nature, which makes it suitable for processes and environments where chemical reactivity must be minimized.

Compressing Argon

Compressing argon involves increasing its pressure, typically for storage or industrial applications. Argon, like other gases, can be compressed using a compressor. Here’s a general overview of the process:

Compressor Selection

Use a compressor suitable for handling noble gases like argon. Diaphragm compressors or reciprocating compressors are often employed for this purpose.

The choice of an argon compressor depends on the required pressure, flow rate, and purity of the compressed argon.


The compressed argon is then stored in high-pressure cylinders or tank containers. These containers are designed to withstand the pressure and are often constructed with materials compatible with high-pressure gases.

Inlet Filtration

Before compression using diaphragm compressors, it’s essential to ensure that the incoming argon is clean and free of contaminants. Filtration systems are often used for this purpose.

Safety Considerations

Safety is a crucial aspect of working with compressed gases. Diaphragm compression systems should include pressure relief devices, and operators should be trained on safe handling procedures. Compressed gases, including argon, should be stored and handled in accordance with relevant safety regulations.

Compression Process

The diaphragm compressor takes in argon gas at a certain pressure and as a gas booster, compresses it to a higher pressure. The compression process increases the temperature of the gas. Depending on the system, there may be cooling stages to control the temperature.


Compressed argon can be distributed through pipelines or in cylinders, depending on the specific application.


Compression of argon generates heat, and excessive heat can be detrimental. Cooling systems are often incorporated to remove the heat generated during compression. This can involve intercoolers and aftercoolers.

Important Notes

Argon, being an inert gas, doesn’t react readily with other substances. However, safety measures are crucial, especially when working with compressed gases.

The choice of compression equipment and process parameters depends on the specific requirements of the application, such as the desired pressure and purity of the compressed argon.

Always follow industry guidelines, safety protocols, and manufacturer recommendations when working with compressed gases to ensure a safe and efficient process.

Why Argon Compressor Manufacturer PDC Machines?

Safety interlocks

PDC’s argon compressors are completely instrumented for safe and automatic operation.

Fast Acting Leak Detection System: Included with every PDC argon compressor is a leak detection system. This system detects diaphragm or seal failures. Our leak detection system monitors the gas and hydraulic sides of the compressor and will sound an alarm and/or shut down the compressor when it detects an anomaly or failure.

Leak-free argon compression: PDC’s compressors compress argon in an ultra-pure state.  There is no contamination of the argon gas during compression.

Unique Oil Distribution System

PDC argon diaphragm compressors hydraulic systems are designed in such a way as to ensure uniform diaphragm deflection, prevent knocks, vibration, cavitation and yield smooth, and quiet compressor operation.
