WITA® Delta HE 75F

0,00

The WITA® High efficiency pumps can reduce energy consumption by up to 80% compared to a standard circulation pump, whilst maintaining the same level of hydraulic power.

With this pump, eleven different performancecurves can be selected. In addition to the six characteristics which operate according to the proportional pressure method, five further can be selected with a constant characteristic curve. Through the switchable night reduction, the power consumption can be reduced once the system temperature has been lowered. The LCD display shows the current power consumption, the selected characteristic curve and the night reduction.
