Discover other configurations:
MRU (Mobile Refuelling Unit) is an integrated all-in-one solution for rapid and safe refueling of vehicles powered by natural gas or biomethane.
It is available in both a mechanical compressor configuration, ideal for high duty cycles with operational continuity, and a hydraulic version, which is more compact and quieter.
Both configurations include three-line priority panel (high, medium, low pressure), electrical panel, control system, and two refueling points with mass meters.
All components are housed in a compact, modular enclosure with two separate rooms to maximize safety and ease of maintenance.
