A CNG refilling station according to the present invention may include compression units, storage units and/or control units that may be assembled together in any order or quantity to form a gas refilling station of any size. The units may be assembled on-site and may easily be attached, removed or reconfigured. Once the units are assembled, a control unit (or units) may automatically communicate with all the other units to work as a single gas refilling station. The design allows for reconfiguration, where additional units can be added to increase compression, storage, or dispenser capacity as needed. The design also allows for units to be easily replaced and/or maintained and arranged to accommodate for location constraints.
