The design and manufacturing of reciprocating machine products adhere to the latest international and domestic standards such as API618 and SH/T 3143, incorporating advanced technologies from both domestic and international sources. This has resulted in a series of large, medium, and small models, ranging from piston forces of 4.5T to 80T.

 The compressed medium consists primarily of methane with minor amounts of nitrogen and ethane. Its normal operating temperature ranges from -144℃ to -120℃. It is primarily used for the recovery and recondensation of low-temperature evaporated gas in the low-temperature tank area, either for return to the tank or for pressurization and export.

 It is primarily used in low-temperature BOG compressors and BOG booster export compressors in large-scale LNG receiving stations along the coast and liquefaction plants in inland areas. Currently, its main application achievements include the second and third phases of Sinopec Qingdao Liquefied Natural Gas Co., Ltd., the second phase of Sinopec Tianjin Liquefied Natural Gas Co., Ltd., etc., with a maximum processing capacity of 14t/h@-120℃.
