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.
