Please select model that has value of used air content calculation result below.
Processing air ow of dryer= Standard air ow × [ Correction coefcient for each model × Temperature correction coefcient (In air
temperature
•
Pressure dew point
•
Ambient temperature)] × Pressure correction coefcient
Note: ( Correction coefcient for each model × Temperature correction coefcient)’s maximum value is Maximum
coefcient.
In case ( Correction coefcient for each model × Temperature correction coefcient) exceeds this value, please
calculate by Maximum coefcient.
<Calculation example>
For GX8215D with Inlet temperature 35°C • Ambient temperature 32°C • Outlet pressure dew point 10°C • Air pressure 0.7MPa,
calculate process amount:
( Correction coefcient for each model × Temperature correction coefcient) = 0.9 × 1.38 = 1.242
Since it does not surpass GX8215D’s maximum coefcient of 1.53, dryer processing air ow is:
2.80 (Standard processing air ow) × 1.242 × 1.0 = 3.47 m
