Abstract

The present invention relates to an apparatus for degassing liquids comprising a degassing system, wherein the degassing system has a first degassing chamber, a second degassing chamber, a liquid store, a pump, and a supply line that connects the liquid store to the first degassing chamber; wherein the pump is connected to the first degassing chamber at the intake side and to the second degassing chamber at the pressure side; and wherein the degassing system furthermore has a return line that can be cut off and that connects the two degassing chambers to one another, and wherein the apparatus comprises a controller that is configured to operate the degassing system in a first operating mode and in a second operation mode; wherein the degassing system is connected in the first operation mode such that the pump conducts liquid away from the first degassing chamber and supplies it to a removal unit for degassed liquid; and wherein the degassing system is connected in the second operating mode such that liquid is returned from the second degassing chamber to the first degassing chamber through the return line.
