A closed recirculating liquid system comprising a piping system for carrying a recirculating liquid and a deaeration system, the deaeration system comprising a membrane system with a porous membrane device being substantially permeable to gases and substantially impermeable to liquids, a membrane housing in which the porous membrane device is arranged, and an inlet and an outlet connecting the membrane housing to the piping system in such a way that at least a part of a recirculating liquid may be lead into the membrane housing, along a first side of the porous membrane device and returned to the piping system, and wherein the deaeration system further comprises a vacuum device with an inlet connecting the vacuum device to the membrane housing in such a way that a vacuum may be provided on a second side of the porous membrane device opposite the first side of the porous membrane device such that gas may be removed from the recirculating liquid and an outlet for evacuating the gas removed from the recirculated liquid to the external of the vacuum device. |
