liquefy sf6 gas filled Calibration

During the gas recovery process the SF 6 is stored either in gaseous or in liquid form. Furthermore, the air is evacuated from gas compartments after maintenance works. Then, the gas compartments are refilled with SF 6 to the desired operating pressure. The gas is led via filters and is purified once again while filling.
