CNG Booster HD

It elevates everything to the nth power.
The results too.

Designed for medium-sized charging stations, the CNG HD series boosters can compress up to 250 bar of natural gas and biomethane previously treated and filtered from the power line.
Designed for professional use, thanks to the four compression stages and low rpm. The remote control panel, supplied with a 5 meter cable, provides all the indications to operate in maximum safety.

High-pressure 4-stage methane pumping unit.

Simplicity comes standard.

Imagine having a compressor capable of great performance and endowed with extraordinary solidity. What would all this be without absolute simplicity in managing it?
We believe that innovation is for this: to make everything simpler.

With them you are safe.

Coltri CNG compressors put safety first: they are equipped with sensors that stop the machine in case of leaks; and are equipped with inlet and outlet solenoid valves to regulate the operation of the machine and the system.
