Dry Compressed Air for Cold Areas
The water still left in the compressed air in the system gets frozen overnight, maybe to 10 degrees F. The ice then cracks all kinds of pneumatic brakes, air regulators, etc. How low a dew point should be looking for? The building cannot be heated because of flammables. We have a 25 hp compressor, 120 gallon tank and running at about 100 psi. Thank you.
Bill says...As long as the air exiting your compressor has a
DEW point this is higher than the temperature of the compressed air lines the air is running through, you will get condensation in the lines.
If the ambient temperature drops below freezing, then water in the lines and in compressor tank will freeze, creating many issues, some of which you have described.
You need to read the pages relating to water in your compressed air, and the subsequent pages that describe
why there's water, and what to do about it. Cheers,
Bill
