Hydrogen Hydraulic Compressors - Duplex/Twin

The Duplex/Twin hydraulic compressor is designed for the compression of hydrogen, CNG and RNG in applications requiring reliable gas compression at pressures of up to 280 bar.
The system is based on Idro Meccanica's hydraulic compression technology. The compressor uses a hydraulic transmission in which an oil piston is connected to the gas pistons by a steel rod. Hydraulic pressure moves the piston assembly, compressing the gas inside the gas cylinders.
The Duplex/Twin configuration provides a flexible compressor arrangement for applications requiring increased compression capacity and operational flexibility.
The compressor operates with two compression stages and is available with suction pressures ranging from 14 to 32 bar. Maximum delivery pressure is 280 bar, with a maximum flow rate of 2,000 Scm/hr.

Key features

Reliable Hydraulic Compression: The hydraulic compressor design uses a simple mechanical arrangement with a limited number of moving components. The piston rod connects the hydraulic and gas pistons and transfers the hydraulic force required for gas compression.
Separation of Gas and Hydraulic Sections: The gas and hydraulic sections are separated by a long distance piece. Separate sealing systems on the gas and oil sides help prevent oil contamination during gas compression.
Low Gas Loss: The compressor specification states a gas loss of 0%, supporting efficient handling of compressed gas.
Long Maintenance Interval: The compressor is designed for maintenance intervals of up to 5,000 operating hours. Self-lubricating PTFE-based wear components are used in the compressor design.
Flexible Duplex/Twin Configuration: The Twin configuration provides an alternative to a single compressor arrangement and can be used where greater compression capacity or operational flexibility is required.

Applications

Simultaneous download of multiple trailers
Continuous power supply of daughter stations or urban networks
High pressure variability applications

SAFE S.p.A.

SAFE S.p.A. is an Italian engineering and manufacturing company specializing in compression and gas-distribution systems, with its headquarters and production activities located in the Bologna area. The company serves natural gas, biomethane, hydrogen and industrial gas applications and combines compressor technology with mechanical packaging, storage, controls, safety systems and station-level integration. Hydrogen is one of SAFE’s established application areas: the company develops compressors for pure hydrogen, packaged refueling stations, high-pressure storage and mobile solutions that can be integrated downstream of electrolysis or other hydrogen sources. SAFE also offers virtual-pipeline configurations in which hydrogen is compressed at a mother station, transported in high-pressure containers and unloaded or conditioned at a daughter station, as well as grid-injection and on-site generation/refueling concepts. Its role therefore extends beyond the compressor itself into the engineering of complete hydrogen handling installations. Within the hydrogen value chain, SAFE is positioned between production and end use, enabling compression, storage, logistics and dispensing for mobility, industrial and distributed-energy applications.
