COMPRESSION SYSTEMS

SAFE has been at the forefront of gas compression for over 50 years, excelling in CNG, Biomethane, and Hydrogen compression technologies. SAFE leverages its advanced engineering capabilities to deliver reliable, high-efficiency compressors, turnkey solutions for many applications including BIOGAS Upgrading, and comprehensive support worldwide.

Since 2009, SAFE has expanded its technology to include complete biomethane plants, and more recently, Hydrogen compression solutions, offering oil-free compressors and modular skid-based systems for stationary or mobile applications. These innovations support decarbonization goals across CNG, biogas, and hydrogen refueling infrastructures.

SAFE products allow construction of various kinds of CNG stations and thus customers have a wide range of possible choices according to their specific requirements and configurations. Typically a CNG refuelling station is designed as a function of different site specific parameters such as:

  • Availability of natural gas from the pipeline or from trailers
  • Pipeline pressure
  • Average daily demand of natural gas (flow rate)
  • Peaks hours CNG demand
  • Power capacity available at site
  • Type of vehicles to be refueled

A correct choice of the CNG station design shall consider all of the above variables with the aim of obtaining the best performances with the minimum investment.

Achieving this aim for SAFE means:

  • Maximum refueling speed
  • Minimum engagement of electric power and the minimum energy consumption for the compression
  • Bigger reliability with minimum risks of station stopped for maintenance
  • Minimum encumbrance for installation of a plant in a refuelling stations with multiple fuels
  • Plant modularity which allows to accompany the development of the station CNG demand

Thanks to its technological know-how gained in the gas treatment and compression fields since 1975, SAFE has celebrated the newborn biogas division opening in 2009, with the first biogas upgrading pilot plant delivered and put in operation at San Giovanni in Persiceto (Italy). Since then, SAFE has been keeping optimizing and innovating its compression-core products, for providing all Customers with the most reliable and best performing technology.

BIOGAS APPLICATION:

  • Turnkey solutions, offering a complete system from the digester to the high pressure compressor for vehicles refueling, or re-injection into the pipeline network
  • Biogas purification systems
  • Compressors for biomethane
  • Storages
  • Dispensers
  • Reducing and metering cabinets
  • World Wide Assistance

In addition to CNG and Biogas, SAFE now offers advanced hydrogen compression systems. These systems are engineered to meet the highest standards of purity, efficiency, and modularity.

  • Oil-free compression for ultra-clean hydrogen service and full compliance
  • PTFE self-lubricating seals and distance-piece piston design ensure total gas separation and system integrity
  • Compression stages up to 700 bar, ideal for hydrogen refueling stations
  •  Modular, customizable skids for stationary installations or mobile refueling units
  • Digital control systems for real-time monitoring, diagnostics, and low-maintenance operation
  • Versatile application across industrial use, energy storage, and hydrogen refueling infrastructure
