Let’s discuss how everyone prevents their instrument air from freezing in winter Also, how are the instrument air pipelines distributed?

In the instrument air pipeline, air from the compressor flows into the air storage tank; after being dried, it enters the instrument air pipeline and is distributed to various instruments for use. In winter, however, the pressure reducing filters and instrument valve positioners always freeze up, which affects their functionality. Is there any good solution to this problem? !

The quality of the instrument air does not meet the requirements; its dew point should be 10° lower than the lowest ambient temperature, so that freezing will not occur.

The question is how to ensure that the quality of instrument air meets the required standards. Should it pass through a dryer first? Won’t the moisture in the dryer freeze in winter?

It won’t freeze. The instrument air in our facility doesn’t freeze. There is still too much moisture in your instrument air.

The quality of instrument air is clearly specified in the \"HGT 20510-2000 Regulations for Instrument Air Supply Design\"; it is recommended to install a dew point meter on the main instrument air pipeline for testing!

What was said on the 6th floor is correct; moreover, if the quality of the instrument air is poor, it may also damage the instruments that use that air.

It is best to use an adsorption drying system with heat-free or mild heat regeneration; cold dryers are not effective. The quality of handling is the key factor. Secondly, keep the valve below the air storage tank slightly open at all times to allow water accumulation to be blown out. Or several times a day.

The quality of the instrument air does not meet the standards; contact the supplier to resolve this issue.

The exhaust valve of the air storage tank for instrument air is still on all the time! Also, the dryer we use is a heat-free regeneration adsorption dryer! But there’s still water! Sea friends, please help me think of a solution! Let’s analyze what causes the presence of water Is there any good way to solve this! Thank you all first!
