COLUMN-SHAPED DEGASSING APPARATUS FOR HEMETICALLY CLOSED PIPING

摘要

PROBLEM TO BE SOLVED: To achieve the mimaturization and weight reduction of a column- shaped degassing apparatus for hemetically closed piping of a building or the like. SOLUTION: In the column-shaped degassing apparatus for hemetically closed piping of the building or the like, the column-shaped degassing apparatus 4 is connected to the circulating water supply line 2 branched from the hermetically closed piping 1 through a degassed water extraction line 3 and an extraction pump 8 low in suction pressure and high in discharge pressure is disposed in the degassed water extraction line 3.
