Designed for medium-sized filling stations, CNG HD series compressors can recompress up to 250 bar of natural gas and biomethane previously treated and filtered from the supply line. Four stages of compression and low rotation speeds make the machine suitable for professional use. The remote control panel (5-meter cable) provides all the indications to operate in maximum safety. — There are two installable pumping units (CNG 20 and CNG 24), with different flow rates, both powered by three-phase electric motors. The standard equipment includes a 4.5 m high-pressure tube and delivery gun with NGV1 direct drive suitable for filling pressures of up to 250 bar. The safety pressure switch for intake gas suction, autostop and the double filtering system with Hyperfilter are always standard.
