Wilo-CronoBloc-BL-E

Electronically controlled glanded single pump in monobloc design with flange connection and automatic power adjustment.

Pumping of heating water (acc. to VDI 2035), chilled water and water/glycol mixtures without abrasive substances in heating, chilled water and cooling systems.

Operating modes
