CNG HD
Professionally,
a compressor ahead.
Designed for medium-sized charging stations, the CNG HD series compressors can compress up to 250 bar of natural gas and biomethane previously treated and filtered from the supply line. Four compression stages and low rpm for a machine suitable for professional use.
The remote control panel (5 meters of cable) provides all the indications to operate in maximum safety.
The compressors are equipped with a 4.5 m high pressure hose and a NGV1 direct connection dispensing gun, suitable for refill pressures up to 250 bar.
High-pressure 4-stage methane pumping unit.
