SAFE S.p.A., a leading provider of compression solutions for biomethane, CNG, and hydrogen, introduces its new screw compressor package designed specifically for biogas upgrading to biomethane. The unit is engineered for continuous 24/7 operation, high energy efficiency, and seamless plant integration. Available in a containerized “plug & play” format, it reduces installation and commissioning time. The compressor will be showcased live at Ecomondo, Rimini Expo Centre, from November 4–7, 2025, at SAFE’s stand D5/114-215.
The new SAFE compressor has been developed to operate under very low suction conditions (100– 500 mbar), maintaining stable performance with variable flow rates up to 2,500 Sm³/h and
discharge pressures up to 16 barg. The new screw-compressor range spans installed power up to 400 kW, making it suitable for integration in both small- and large-scale plants. The water-cooling system (with SAFE-supplied air cooler — installable on the top of the container or at ground level alongside it) and the oil-flooded screw configuration, with triple gas filtration, ensure thermal stability, reliability and service quality. The sound level of the compression package in operation is limited to 60 dB(A) @1 m.
The heart of the unit is the compressor body on a slide-out removable skid, a solution that enables immediate access and fast replacement during maintenance services. Machine control is oriented toward maximum efficiency: service regulation is based on maintaining suction pressure, with automatic motor speed adjustment, and a recirculation line to handle processes with variable flow rates and pressures — extending the operating envelope. Options include a heat recovery system, sub-cooling with chiller and outlet biogas temperature control. These extensions have been developed and made available to increase overall service efficiency and facilitate integration with plant interfaces.
Riccardo Bagagli, Chief Technology Officer SAFE, comments:
“With this new screw compressor, we are providing the biomethane market with a robust, efficient and easy-to-integrate industrial platform, capable of continuous operation and optimizing consumption even in the presence of variable flow rates and very low suction. The goal is to give customers a ready-to-use solution, scalable and configurable on existing plants, that reduces commissioning times and maximizes reliability over the life cycle.”
