From your car to small fleets: charging is green
Created to recompress previously treated and filtered natural gas and biomethane. They are suitable for both domestic and small fleet use. The products in the line CNG Evo are equipped with an electronic control and control unit, equipped with the automatic stop function when the tank is full and advanced safety systems.
Simplicity comes as standard
Imagine having a compressor capable of great performance and endowed with extraordinary robustness. What would all this be without absolute simplicity in operating it? We believe that’s what innovation is for: to make it simpler.
With them you are safe
Compressors CNG Coltri put safety first: they are equipped with sensors that stop the machine in case of leakage; and they are equipped with solenoid valves at the outlet and inlet to regulate machine and system operation.
