Sumitomo F50 Compressor Manual __full__ Jun 2026

Check the self-sealing Aeroquip couplings for dust, debris, or damage.

The Sumitomo F-50 is a water-cooled, three-phase helium compressor designed to deliver high-purity helium gas to cryogenic refrigerator cold heads. Key Specifications

Usually ranges between 0.4 and 0.6 MPa. Front Panel Indicators

Never tilt the unit more than 30° during transport or setup to avoid oil migration. Cooling Water: Flow Rate: 7–10 L/min (1.8–2.6 gal./min). Temp Range: 4–28°C (39–82°F). Restriction: Do not use demineralized water. Check the self-sealing Aeroquip couplings for dust, debris,

Maintain an environment between 5°C and 35°C. High ambient temperatures degrade oil quality.

Operating the Sumitomo F50 compressor efficiently requires strict adherence to its physical, electrical, and environmental specifications. Electrical and Physical Specs

If the static pressure drops below the recommended range, helium must be added following strict purity protocols. Front Panel Indicators Helium gas leak in the

If your original manual is lost or destroyed, you have three legitimate options:

: Removes lubricating oil mist and debris from the compressed helium to ensure gas purity before it reaches the cold head.

Check your chiller settings. Ensure the water valves are fully open and the water pump is delivering adequate pressure.

Proper installation is critical to prevent premature component failure and ensure optimal cryogenic performance. Location Requirements
