–ADVANTAGES

STRONGER AGAINST CORONA ELECTRIC DISCHARGESince Corona Electric Discharge is easy to occur under Helium gas ambience, Hitachi apply “High Pressure Chamber” structure & exclusive motor. Which is especially suitable for inverter control because higher surge voltage is generated from inverter. Therefore, Hitach “High Pressure Chamber” structure has advantage on life time of motor and reliability of compressor. [Under patent application]

(1) The compressor is cooled by injected oil.(2) Net weight include oil, but oil is not charged at time of shipment. Because of hydroscopic property, it should be charged by customer side.(3) The gas flow rate is converted into values at atmospheric pressure (32.0ᵒF=0ᵒC).

The flow rate is based on the condition shown in below table.(4) S251AH, S250AH, S403DH, S503DH, S603DH, GA120SHA and GA150SHA are with oil sight glass.(5) cfm values are calculated with below conditions.
