CNG RC

Even small, it works great.

Designed to recompress previously treated and filtered natural gas and biomethane. These compressors are designed for refueling vehicles powered by natural gas. They are suitable for home use or for small fleets. The use of the products of the CNG RC line is simple and safe, they are equipped with an electromechanical remote control panel with 5 meters of cable and an automatic stop function when the tank is full.

3-stage high pressure pumping unit for methane.
