Cooler for compressors makes short work with gases

Compressor systems are used in industrial processes such as air separation, gas liquefaction or the production of chemical and metallic base substances. Gaseous media are compressed to higher pressures and thus warming them up.

For technical and commercial reasons, gaseous media such as air, oxygen, nitrogen, carbon monoxide, carbon dioxide, methane etc. have to be cooled down after compression.

Mechanics of the cooling process
In the case of moderate pressure, the compressed and therefore heated gas is conducted through the cooler bundle on the shell side. Since gas is naturally a poor heat conductor, these coolers are often designed with enhanced heat transfer surfaces. These can be finned tubes or platefins from our own production.
On the tube side, the coolant – which is normally water or a mixture of water and glycole – is conducted through the tubes. When the temperature in the cooling process falls below the dew point, condensate will precipitate which is dispersed by demisters integrated in the coolers.
At pressures above 50 bar it is more economical to have the gases flow on the tube side.
