PURPOSE: An index device for a centrifugal heater using pneumatic pressure and an index method thereof are provided to prevent the leakage of supplied water in a housing of the centrifugal heater because the index device arranged between the housing and a shaft injects the pneumatic pressure. CONSTITUTION: A centrifugal heater comprises a housing (200), a shaft (500), an index device (700), and a cell disc (600). The housing has an inlet (210) receiving supplied water from the outside; and an outlet (220) discharging the supplied water to the outside. The supplied water moves in the housing. The shaft penetrates the housing and is rotated by a driving device (300) and a bearing part (400). The index device is arranged between the housing and the shaft to prevent the leakage of the supplied water in the housing. The cell disc is connected to the shaft arranged in the housing. The index device has an injection port (710). |
