CNG 14 EVO - Coltri - CNG High Pressure Compressor - 266 l/min, 15,9 m3/h
CNG EVO
The CNG EVO compressor series has been designed to re-compress natural gas and bio-methane which has already been treated and filtered. These compressors are designed to supply fuel to domestic or small fleets of vehicles powered by natural gas. The electronic control and command unit simplifies their use with an automatic stop function when the tank is full and state-of-the-art safety systems.
The models are powered by a three-phase electric motor when equipped with the CNG EVO 10, CNG EVO 14 and CNG EVO 19 pumping units, however if equipped with the CNG EVO 3, CNG EVO 5 pumping unit it can be powered by a single-phase or three-phase motor.
Standard equipment includes a 4.5 m high-pressure flexible hose with direct-acting NGV1 connection refuelling nozzle suitable for filling pressures up to 250 bar
