Compression technology is a process of reducing the volume of gases, by compressing them to a higher pressure. This technology is used in a wide range of applications, from industrial processes like power generation and oil and gas, to other appliances like food and medicine industry, etc.
In the compression process, air or gas is forced into a smaller space, which increases its pressure and temperature. This compressed air or gas can then be used to other processes and applications. Overall, compression technology plays a crucial role in many industries and helps to increase efficiency and productivity while reducing energy costs.
There are various types of compressors used for this process, including reciprocating, rotary screw, and centrifugal compressors. Each type has its own advantages and disadvantages, depending on the specific application.

On the contrary to compression process, expansion technology is the process of allowing compressed air or gas to expand, which results in a decrease in pressure and temperature. This technology is commonly used in refrigeration, air separation systems as well as power generation and other industrial processes.

When compressed air or gas is allowed to expand, it absorbs heat from its surroundings, which makes it an effective method for cooling while its energy is extracted. This is why it is used in refrigeration and air separation systems, where the compressed gas is expanded to cool the media. Expansion technology is also used in various industrial processes, such as in the extraction of natural gas and crude oil.
