Can anyone tell me how the commercial systems work?
Do they inject antifreeze in the line wth a pressure change or do they pass the air through a reseirvor of antifreeze to dry the air before it is sent down he air line? This would allow small amounts of anti freeze vapor to enter the air line?
Seems to me if you have the air pass through a substance that will take the mositure out of the air you can prevent freeze ups.
