Helium-Refrigerating Scroll Compressors for Cryogenic Applications - 3

General Data Stronger Against Corona Electric Discharge Motor Type (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°F=0"C). 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. 50Hz: 2,880rpm 60Hz: 3,470rpm Since Corona...
