Verify water cooling flow rate and pressure. Check helium supply and return connections to the cold head.
Check water pumps, open valves fully, and verify that the water chiller is functioning. sumitomo f50 compressor manual
Slightly open the regulator and allow helium gas to bleed out of the charging hose coupling for 3 to 5 seconds before tightening it to the compressor. This purges ambient air and moisture out of the line. Open the compressor charge valve slowly. Verify water cooling flow rate and pressure
Provides documentation for compressor units used in MRI systems. Slightly open the regulator and allow helium gas
The Sumitomo F-50 is a water-cooled, three-phase helium compressor designed to deliver high-purity helium gas to a cold head. It compresses low-pressure return gas from the cryocooler and sends high-pressure gas back to drive the cryogenic cycle. Key Specifications
If your pressure drops below the minimum operating threshold, you must add Grade 5 helium gas using a dedicated charging valve assembly.
The F50 compressor features an automated safety interlock system that shuts down operation if vital metrics breach safety thresholds. Symptom / Error Potential Cause Corrective Action Insufficient cooling water flow or high water temperature.
