Lowara LER 200-270 UNL 756 [14/16] Inline pumps and hydrovar

HYDROVAR application example – Control along a system curve

In closed systems for heating or cooling applications most of pressure has to be built up to overcome high friction

losses in the system.

By controlling the provided pressure of the pump along the system curve and the actual demand, energy savings

up to 70% can be realized.

This system characteristic can be programmed in the HYDROVAR without requiring additional external flow measu-

rement devices.
