Wilo-SiFlux-YG2.0-I
The reliable multi-pump solution for heating, air conditioning and cooling applications.
The reliable multi-pump solution for heating, air conditioning and cooling applications.
The Wilo-SiFlux is the ideal solution for heating, air conditioning and cooling applications when high flow rates need to be provided reliably and energy-efficiently for large buildings. The factory pre-assembled multi-pump system requires little installation effort and its compact, space-saving design enables easy integration into confined technical rooms. It is conveniently operated via the Wilo-SCe Smart Controller. It handles the automatic pump control, adapts the output exactly to the current demand and thus ensures optimum system operation at all times. An integrated standby pump guarantees a reliable supply at all times. With highly efficient IE5 EC motors and intelligent power adjustment, the Wilo-SiFlux offers significant potential savings in energy consumption and provides long-term support for efficient building operation.
