Sumitomo F50 Compressor Manual New Patched Page
According to the Sumitomo F-50 technical manual , proper setup is vital for system longevity:
The F-50 comes in two primary variants: the (low voltage) and the F-50H (high voltage). Specification Cooling Method Water-cooled Electrical Supply (F-50L) 3 Phase 200 V, 50/60 Hz Electrical Supply (F-50H) 3 Phase 380-415 V (50 Hz) / 460-480 V (60 Hz) Power Consumption 6.5–7.2 kW (50 Hz) / 7.5–8.3 kW (60 Hz) Helium Pressure (Static) ~1.60–1.65 MPa at 20°C (varies by model) Helium Pressure (Operating) High side: 1.90–2.20 MPa; Low side: 0.40–0.60 MPa Dimensions (HxWxD) 591 x 450 x 585 mm (23.3 x 17.7 x 19.1 in) Weight ~120 kg (264 lbs) Installation & Environmental Requirements
The is a critical component in cryogenic systems, primarily used to power Gifford-McMahon (GM) cryocoolers and pulse tubes . Part of SHI's Freedom® series, this mid-size, water-cooled unit is designed for high-reliability applications such as MRI magnets and laboratory cryostats.

The hot, high-pressure gas passes through a water-cooled heat exchanger and an oil separator to remove lubricating mist.
An adsorber (active charcoal) removes remaining oil vapors before the pure helium is sent back to the cold head. Maintenance and Servicing According to the Sumitomo F-50 technical manual ,
The unit should never be tilted more than 30° during transport or operation.
To maintain 4K or 10K cryogenic temperatures, regular maintenance is mandatory: Sumitomo f50 Compressor Manual | PDF - Scribd To maintain 4K or 10K cryogenic temperatures, regular
Low-pressure helium returns from the cold head through a return connector.
Operates best between 5°C and 35°C (41–95°F). Capacity may degrade by 5% if temperatures exceed 28°C.
The compressor functions by circulating high-purity helium gas:
