Total power dissipation Pv in kW
Total volume flow
• The minimum volume flow is dependent on the total power dissipa-
tion. This can be found in the technical data.
• The resulting volume flow has to be in the recommended operating
range of the temperature difference.
• Maximum temperature difference (ΔT) between flow and return
flow 6 K.
• A volume flow above 140 l/min increases the risk of erosion in the
cooling system.
• A discontinuous mode is not permissible.
• Pay attention to flux direction and check tightness.
