It's read at the end of the fill with ambient/water temperature around 70 Fahrenheit /21 Celsius. The water chiller does not have any refrigeration ability so it's largely related on the ambient temperature. The high pressure air tubing can go up to 80-90 Celsius depends on the environment...

Yes the downside of two stage setup is it will increase the air build up time especially when you filling directly to a gun or small cylinder. For large tank refill it wouldn't be an issue.
