Type L CNG Compressors: The type L CNG compressor is so called because of its L-shaped overall structure design. It offers capacity between 500 and 1500Nm3/h, and is often used for small-sized CNG filling stations. It is mainly composed of the compression unit, anti-explosive electric motor, cooling unit, lubrication unit, internal connection pipeline, safety valve, and the blow-down valve. All these components are skid-mounted on a common base, thus facilitating installation and transportation. The PLC control cabinet is usually positioned inside the control room of CNG filling stations so as to realize remote control on the CNG compressor.
