Natural gas from distribution pipeline is compressed by using a high-performance compressor. The compressed gas is stored and distributed in mobile cylinders up to the customer’s location. CDS with what so-called mother-daughter station concept makes it even more mobile. It is possible to reach customers which are located in remote areas and far from the existing gas reserves or distribution pipeline as well as those who need extra sources. CNG also offers clean and efficient burning, which results not only lower maintenance cost but also environmental friendly.
