CNG Booster RC

Compact, robust, performing.
And a lot of Coltri.

Designed to compress previously treated and filtered natural gas and biomethane with a suction pressure between 2 and 8 bar and a final pressure of up to 250 bar.
Robust and compact, created to fill cylinders for gas storage. The use of the products of the CNG BOOSTER RC line is easy and can be done in total safety. The equipment includes a remote electromechanical panel with 5 meters of cable for control and automatic stop function when the tank is full.

3-stage high pressure pumping unit for methane.

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.
