Compressor Manual New - Sumitomo F50

Typically available in 3-phase configurations (e.g., 200V, 380V, 400V, or 480V depending on the specific sub-model) Weight: Approximately 120 kg (264 lbs)

The Sumitomo F50 is a water-cooled, three-phase helium compressor designed to deliver high-purity helium gas to cryogenic cold heads. It is engineered for high reliability, low vibration, and continuous operation. Key Specifications High-purity Helium gas (99.999%)

| Parameter | Specification | | :--- | :--- | | | 591 x 450 x 485 mm | | Compressor Weight | Approx. 120 kg | | Maximum Tilt | Never exceed 30° from vertical when handling | | Orientation | Vertical only; the cold head must never be bent | sumitomo f50 compressor manual new

Because the F50 uses a three-phase motor, verifying correct phase rotation is critical. Incorrect rotation can damage the internal scroll capsule. Most units feature a phase-order indicator light to alert you to wiring errors.

To prevent helium expansion damage or system contamination, operators must track the cooldown cycle and manage power-downs precisely. Typically available in 3-phase configurations (e

: The electronic controller’s hidden menu (press and hold ‘Set’ + ‘Down’ for 10s on the F50C panel) shows actual air-end discharge temp in °C even if the display only shows ‘Normal’. This is the first sign of varnish.”

Proper adherence to the framework outlined in the Sumitomo F-50 Technical Manual ensures the maintenance of stable cryogenic environments (4K to 10K), optimization of energy efficiency, and prevention of premature component failure. 1.

The F-50 series generally features the following specifications based on technical documentation: : Mid-size, water-cooled, three-phase helium compressor. Power Consumption : Typically 6.5–7.2 kW at 50 Hz and 7.5–8.3 kW Water Cooling : Requires a flow rate between 1.8–2.6 gal/min (approx. 7–10 L/min) and water temperatures between Maintenance Cycle

The Sumitomo F50 series is not a single model but a family with variants designed for different power grids and performance requirements. Understanding the specific model number is crucial for operation and maintenance. Key specifications for two common variants are provided in the tables below.
