Compressed Air Dryers
Turn up the heat on your compressed air, but cast out the condensate.
Air compression makes moisture. You raise the temperature of the air to compress it and bingo, when it cools you have water vapour. It's unavoidable - and annoying if your application demands unadulterated compressed air. Left untreated the moisture in the newly produced air can damage pneumatic equipment and contaminate your final product - and no one wants to use 'soggy' paint sprayers.
So we'll want to remove it. The condensate as it's known, needs to be literally 'dried' and this can be done in one of two (main) ways: via refrigerant (primary drying function) and desiccant (secondary ie let's really wring this out), dryers.
There are other primary and secondary ways of removing the water, yes, but we'll be sticking with these two. How much moisture they take out of the air is measured as the 'dew point'. A refrigerant dryer will take your air to a dew point of 2 -3 degrees. A desiccant dryer will bring this down to a dew point of around -40 degrees celsius
