Sumitomo F50 Compressor Manual New Jun 2026

The is a high-performance, mid-size refrigeration core designed to drive advanced cryogenic systems like Gifford-McMahon (GM) cryocoolers and pulse tubes . As a staple component in high-tech medical imaging equipment—including GE HealthCare MRI systems like the Signa Horizon LX 1.5T and Discovery MR750 3.0T—it delivers the steady gas pressure necessary to maintain extreme cooling.

Use two wrenches to tighten the couplings to prevent twisting the internal copper lines of the compressor or cold head. 4. Operation Protocols Pre-Start Checklist Verify water cooling valves are open and water is flowing. Confirm helium static pressure is within the nominal range.

The F50 relies heavily on a stable supply of cooling water to extract heat from the helium compression process.

The static pressure (when the unit is off and at room temperature) should match the specifications on the unit's rating plate—typically around .

To maximize the lifespan of your Sumitomo F50, strict adherence to the manual's maintenance schedule is required. Action Required Pressure & Water

The rear and front operation panels contain vital touchpoints required for installation and daily oversight. Reviewing the technical schematic reveals several essential interfaces: The F50 relies heavily on a stable supply

While the F50 is designed for reliability, it requires periodic maintenance. Some tasks are straightforward, while others should be left to specialists.

The F-50 comes in low-voltage (F-50L) and high-voltage (F-50H) versions to fit different electrical setups. Specification 6.5 to 7.2 kW (50 Hz) / 7.5 to 8.3 kW (60 Hz) Electrical Supply (F-50L) 3-Phase, 200 V, 50/60 Hz Electrical Supply (F-50H) 3-Phase, 380/400/415 V (50 Hz) or 460/480 V (60 Hz) Static Gas Pressure 1.45 to 1.65 MPa at 20°C (depending on the cold head) Cooling Water Flow 7 to 10 Litres per minute Dimensions (H x W x D) 591 mm x 450 mm x 585 mm Total Weight 120 kg (264 lbs) Maintenance Cycle Every 30,000 hours of operation Unboxing and Site Requirements

Thread the supply and return lines securely into the labeled "IN" and "OUT" water ports. Electrical Connections Some tasks are straightforward

Use a dedicated 20A or 30A circuit breaker depending on your specific voltage configuration. 4. Operation and First-Time Startup Follow this step-by-step sequence for initial startup:

Connect a helium bottle equipped with a pressure regulator to the charge valve on the compressor.
