SCG Series Screw Gas Ends

In gas compression systems where operating conditions fluctuate, achieving consistent efficiency requires precision control. The SCG Series screw gas ends are engineered to deliver exactly that—reliable oil-injected compression combined with adaptable performance control.

Designed for OEM integration into industrial and process systems, the SCG Series offers a focused solution for low pressure ratio applications, enabling optimal efficiency through advanced design features such as variable Vi (internal volume ratio) control. The result is a gas end that balance performance, adaptability, and reliability across a wide range of gas duties.

Unlike general-purpose gas compression elements, the SCG Series is tailored specifically for applications with lower pressure ratios, where precision and efficiency are essential.

This design approach ensures that:

• Compression work is matched more closely to system requirements
• Energy losses from over- or under-compression are minimized
• Stable flow is maintained across variable operating conditions

Such optimization makes the SCG Series particularly suitable for process and energy systems where maintaining consistent performance over a defined pressure window is critical.

A defining feature of the SCG Series is its variable Vi system, which allows the internal compression ratio of the gas end to be adjusted based on operating conditions.

This capability provides key advantages:

• Improved efficiency across different pressure ratios
• Reduced energy consumption compared to fixed-ratio designs
• Greater flexibility when handling fluctuating process demands

For OEMs and system designers, variable Vi means the gas end can be tuned to match specific applications, helping achieve optimal performance without redesigning the entire compressor package.

The SCG Series focuses on delivering reliable performance within a defined but highly effective operating range:

• Flow capacity from approximately 2.5 to 13 m³/min
• Maximum discharge pressure up to 24 barg
• Power range up to approximately 110 kW, depending on model

Available in compact configurations such as the SCG10 and SCG14, this range is ideal for mid-size industrial systems, where efficiency, footprint, and reliability must be balanced carefully.

For OEMs, the focused performance envelope simplifies system design while ensuring high consistency across applications.

The SCG Series uses oil-injected rotary screw technology, enabling improved sealing, cooling, and operational stability.

In gas compression, this delivers several practical benefits:

• Reduced internal leakage for improved volumetric efficiency
• Effective heat management during compression cycles
• Smooth, continuous operation even under variable load

Combined with mechanical seals, integrated gearboxes, and high-quality bearings, the design ensures long-term reliability even in demanding industrial environments.

This makes the SCG Series a dependable solution for OEM systems requiring consistent performance over extended operating periods.

The SCG Series is designed as a bare-shaft, single-stage gas end with integrated gearbox, making it easy to incorporate into a wide range of compressor packages.

For OEM manufacturers, this translates into:

• Flexibility in selecting drive configurations
• Simplified mechanical layout and assembly
• Compatibility with compact or modular system designs

The combination of compact size and adjustable Vi performance also enables more efficient packaging, particularly in systems where space and layout constraints are critical.
