Sichuan Province is the earliest and fastest growing province for CNG vehicles in China. The application of domestic and foreign equipment in Sichuan provides a good reference for the choice of owners. With the continuous development of the CNG industry, more and more companies are participating in competition at home and abroad, and more and more manufacturers are able to provide users with complete gas station equipment. However, when the owner of the website decided to invest in the construction of the station, he found that in addition to the difficult approval procedures such as municipal planning, environmental monitoring, and land acquisition, he had to face a lot of professional equipment. Because the gas station has a wide range of equipment and professionalism, it does not take time and effort to study it, which may lead to blind decision-making. This is definitely different from the construction of ordinary gas stations. Therefore, China's CNG automobile industry should flourish. In addition to the support and encouragement of the state in economic policy, the research and popularization of the overall technology of gas stations should be carried out as soon as possible. After extensive research on the compressor technology and market of CNG filling stations at home and abroad since 1993, combined with the introduction of the American Dray Sailand RDS natural gas compressor technology, the company produced under the guidance of well-known domestic compressor experts at the end of 2000. The first fully automatic control air-cooled skid-mounted CNG compressor unit in China. The whole machine technology level is leading in China, and the design of PLC automatic control system is even better than imported similar units. Due to its complete configuration, simple operation and convenient installation, the unit has been in good condition in the Zhongyuan Oilfield No. 2 gas station and has been highly praised by users.
