13.7 -
Available external static pressure - units with hydraulic module (fixed-speed or variable-
speed pump, 50 Hz)
Data applicable for:
-
Fresh water 20 °C
-
In case of use of the glycol, the maximum water flow is reduced.
Warning : With the buffer tank module option, the curves below do not take the pressure drops for this component into
account. If necessary, refer to the buffer tank characteristic curves to correct the data below.
