May I ask what devices are used in your units to treat the instrument air supply in order to ensure that the air is dry? Thank you!!

The instrument air supply used in our facility often contains water, which causes problems with valves and positioners. I would like to know what devices are used in your facilities to treat the air after it comes out of the air compressors, so as to ensure that the air is dry. Thank you!!
Thank you. Do you need any other equipment?
Methods such as cooling, adsorption, and freezing of the gas source, as well as increasing the size of the gas storage tank, can also be effective (with regular drainage).
With the drying unit in place, the dew point temperature of the outlet instrument air is required to be around minus 40 degrees
Oil filter, dry cooler, instrument air buffer tank
Large chemical enterprises use a large amount of instrument air, so they have specialized instrument air dehumidifiers for processing it
1. There is an air filter in front of the air compressor; it seems to be of the paper type. 2. Behind the air compressor, there are: a filter – a dryer – another filter – and an air storage tank. If necessary, a dehydration-type pressure reducing valve can also be installed before the regulator. In this way, the moisture content in the instrument air will be low enough.

We were separated from the larger space, and the quality of the gas source is excellent
Before adding equipment, it’s a good practice to regularly drain the buffer tanks in each workshop!
