All About Dew Points

With temperatures coming up, it’s time to consider moisture in your air compressor system and when you might have the most water trouble.

It’s all about the dew point. Meteorologists pay a lot of attention to dew point, and if you own an air compressor system and rely on it to keep your operation running smoothly, you’ll need to know almost as much about dew point as your favorite television weather person.

Dew point is the temperature at which air (or any gas for that matter) gets saturated with water, resulting in condensation.

In your air compressor, the pressure affects the dew point. Compression raises the dew point, expansion lowers it.

So, now we’re paying attention to something called the “pressure dew point.” This is the dew point at full pressure in your system.

Remember, too, that warm air carries more moisture than cold air, so as much as possible you want to keep your compressor in a temperature-controlled room to keep that dew point low.

Why is this all important? Depending on what you are using your air for, dew point is either critically important, or not so much.

For example, if you’re running pneumatic tools, dew point is important because generally-speaking water in your system is bad and if you are running in a cold environment your hoses could freeze. Worth paying attention to.

If you are operating a medical, pharmaceutical, or food processing facility- water in your system is considered a contaminant. This can not only cause trouble with your system, but can result in product damage or contamination and that can cost you a lot of money.

We have a wide variety of dryers and our experts know so much about controlling the dew point in your system they’re practically meteorologists (on a smaller scale) so do not hesitate to give us a call or drop us an email and we can answer any questions you might have about dew point and water in your system.
