"World's First" Scroll Compressors for

Cryogenic Applications since 1985

Features

High COP Low Vibration and Low Noise High Reliability Wide Operating Range

Starting Voltage Ratio for Corona Electric Discharge

Since 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, Hitachi "High Pressure Chamber" structure has advantage on life time of motor and reliability of compressor. [ Under patent application ]

Applicable Specification CE UL

This Structure simplified construction (without the tip-seal and thrust bearing) assures stable operation and long life. The mechanical loss is minimised by these optimised forces thus ensuring improved performance.

This system maintains discharge gas and motor temperature at low levels, achieving simultaneously high reliability and high efficiency.

NOTES: (1) The compressor is cooled by oil injection. (2) Compressor net weight includes oil charge, but oil is not charged at time of shipment and it should be charged by the unit assembler. (3) The gas flow rate have been converted into values at atomospheric pressure (32°F= 0°C). The flow rate is based on the condition shown in following table.

(4) *General data of inverter model is calculated at 58Hz. Frequency range : 30~78Hz (5) Power Supply A: 200V / 50Hz, 200-230V / 60Hz *1: 200V / 50,60Hz D: 380-415V / 50Hz, 440-480V / 60Hz *2: 380-480V / 50,60Hz H: 208-230V / 60Hz
