4 bar
Purge air in l/minute at 4 bar *
* the intrinsic permeability is approx. <5% relating to the purge air volume.
Product selection:
Example for selection drying system for:
•
Volume flow utilisation air:
180 l/min
•
Operating pressure:
4 bar
•
PDP reduction:
+5 °C to -20 °C
Search in table for performance data 4 bar
Column PDP inlet “+5 °C“ up to the row “-20 °C“ (PDP outlet)
Search for a value in this row which is larger than the utilisation air flow
Column DEC 5-115S fulfils this requirement with nominal value 240 l/minute
Purge air consumption DEC 5-115S:
72 l/minute must be deducted from the inlet volume flow
Max. utilisation volume flow:
168 l/minute
