Issues with instrument air
Thread Content
Let’s discuss whether instrument air needs to be heated
It is not necessary, as qualified instrument air is free of water, oil, and other impurities; even trace amounts of such impurities do not require heating.
It’s not necessary, unless the instrument air contains moisture.
In principle, it’s not necessary, but in practice I have encountered it. In the north, due to the dry air, many systems do not have air purification units (used to remove water and oil); high temperatures usually do not cause any problems, but in reality, there is still a small amount of water present in the instrument air. When winter arrives and temperatures drop significantly, small ice particles can still form, which block some of the air passages in the valve, preventing it from functioning properly! That’s when heat tracing is needed!
It’s not necessary, because the dew point temperature of the instrument air is lower than the local minimum temperature
Generally, it’s not necessary, unless there is a problem with your instrument air system – after all, who can completely remove all impurities?
