WATER PRESSURE DROP TOTAL HEAT RECOVERY VR
The graph below illustrates the water pressure drop values in kPa depending on the flow rate in liters/second, for the Special
Versions with Total heat recovery (VD) in both the units that operate in the Cooling mode only (IR).
The operating range is delimited by the minimum and maximum values given in the next table.
