ITA-HP Series Screw Gas Ends

High-pressure gas compression demands precision engineering, efficient energy use, and consistent reliability under load. The ITA‑HP Series screw gas ends are designed specifically to meet these requirements, providing oil-injected, single-stage compression with booster capability for demanding applications.

Developed for OEM systems handling natural gas, process gases, biogas, and petrochemical streams, the ITA‑HP Series enables efficient compression where higher inlet pressures are present. By eliminating the need for inlet decompression, these gas ends help preserve energy and improve overall system performance, making them a strategic solution for high-pressure applications.

The ITA‑HP Series is engineered as a booster gas end, capable of operating with suction pressures up to 8 barg and discharge pressures up to 25 barg.

This booster capability allows systems to:

• Avoid energy losses associated with pre-decompression
• Maintain higher overall efficiency across the compression cycle
• Increase system throughput without redesigning upstream processes

For OEMs and plant operators, this results in a more efficient compression solution, particularly in systems where inlet pressure is already elevated and must be increased further.

The ITA‑HP Series delivers a robust performance envelope while maintaining precision control:

• Power range from approximately 37 kW to 350 kW
• Flow capacity from 1.9 to 36 m³/min
• Maximum working pressure up to 25 barg (360 psig)

Available in two sizes (ITA‑HP 13 and ITA‑HP 26), the series is optimized for medium to large industrial compression systems. This range enables OEMs to design scalable solutions for applications that require both high pressure and consistent flow delivery.

The ITA‑HP Series utilizes oil-injected rotary screw compression, a proven technology for managing high-pressure gas applications.

This design supports:

• Enhanced internal sealing for improved volumetric efficiency
• Effective cooling during compression cycles
• Smooth, continuous operation under heavy loads

Combined with high-quality internal components, this approach ensures reliable operation even in demanding duty cycles and harsh process conditions, where temperature control and mechanical stability are critical.

To support high-pressure operation, the ITA‑HP Series incorporates key engineering features including:

• Integrated gearbox for optimized speed matching
• Mechanical seal system for reliable gas containment
• Balance piston design to reduce axial loads

These elements work together to:

• Improve mechanical stability at high pressure
• Extend component lifespan
• Reduce stress on internal components

For OEMs, this results in a gas end that maintains performance integrity even in the most demanding compression scenarios.

The ITA‑HP Series is designed as a bare-shaft gas end, enabling straightforward integration into a wide range of compressor systems.

Key integration benefits include:

• Compatibility with various drive configurations
• Simplified system layout for packaged compressors
• Reduced engineering complexity and faster development cycles

Because it is purpose-built for booster applications, the ITA‑HP Series also allows OEMs to optimize system architecture by reducing the need for additional compression stages or auxiliary equipment.
