(12) Operating Principle
The liquid to be degassed is flowed through a special
synthetic resin membrane placed in the vacuum chamber of
6-channel degassing unit. The molecules of gases
dissolved in liquid are small, and have a higher mobility
than the liquid and a high affinity to the resin membrane.
Therefore, the gases are selectively transmitted through the
membrane and discharged out of the degassing unit.
Thus, the gases are eliminated from the liquid.
