CNG gas station complete equipment

6.1 CNG dispenser

Summary

The general type intelligent CNG dispenser uses our company’s independent development high-performance military rank microprocessor control system, which is mainly used to meter CNG filling for CNG vehicle. The industry leading pressure intelligence computing function ensures one-time fully filling and preventing overfill. Scientific CNG filling speed control ensures the reliable control of CNG filling target pressure.
Our  independent  R&D  microcomputer  controller  uses  military  rank  electronic  parts,  and  passes  the  harsh  environmental suitability, electromagnetic compatibility and safety performance test, which ensures the reliability of microcomputer controller while the CNG dispenser runs under the complex operating environment. We own the proprietary intellectual property rights, there is no obstacle for technology upgrading and rebuilding in future.

6.2  CNG filling/unloading column

Summary
CNG  filling/unloading  column  uses  high-performance  industrial  control  microprocessing  system,  which  is  the  metering equipment used in trade settlement of CNG main station or substation, and mainly filling/unloading & metering for CNG tank car.
Temperature compensation is available as it uses imported mass flow meter with temperature sensor, high accuracy pressure sensor assures the high accuracy metering.
Mass flow meter, manual ball valve, high pressure hose, quick coupling are imported from famous brand abroad.
Designed and manufactured by ourselves, the computer controller uses industrial grade electronic components, and it passed the test of  harsh  environmental  suitability,  electromagnetic compatibility and  safety, which assures the  reliability  of  computer controller in complex operating environment. With proprietary intellectual property rights, there is no any obstacle in technology upgrading and rebuilding in future.
Runner pipe path isΦ22x4, high pressure hose diameter is 25mm, maximum flow reaches 80kg/min.
