Condensate lifting unit for collecting and pumping condensate from heating, air conditioning, and cooling installations. The inlets are secured with adjustable rubber guides. The level control of the condensate lifting unit is carried out with the electrode-level switch. An integrated ball check valve prevents the return of condensate to the tank. Thanks to the modular design, the condensate lifting unit is compact, quiet, and has low power consumption. For operational safety, a visual warning and an alarm contact (NC contact/normally open contact (NO)) are integrated.
