Used Gemini 125 HPSS CNG Gas Compressor – 4 Stage, 300 CFM, 125 HP, Complete System with Cascade, Dryer, Dispensers
Used Gemini Gas Compressor, Model 125 HPSS, 4 Stage 300 CFM. CNG (Compressed Natural Gas) compressor system includes a four-stage, water-cooled, reciprocating compressor designed for efficient gas compression up to high pressures. U.S. Motors 125 HP, 1760 RPM, 460 Volt motor (S/N X783119) and includes an MK-AJ 24" recapture tank (S/N 9605). It is equipped with an EI C36-0527 cooler (S/N 93483) and a three-cylinder ASME cascade system, each cylinder measuring 20" x 11'6", rated for 5,000 psig and 5,711 cu. ft., with serial numbers 43338, 43339, and 43340. The unit utilizes a Marcum 11 Valve Electro-Pneumatic PMV/SMV priority/sequence panel for flow control. Compression is handled by a Quincy F340-80 air compressor rated at 7.5 HP, 460 Volt, with a discharge aftercooler (S/N 6019514). Drying is managed by a Wilkerson DE3 Twin Tower Heatless Dryer housed in a NEMA 4 enclosure (S/N 4339311). Fuel dispensing is facilitated by two DVCO 2020D dispensers with Hansen nozzles, serial numbers 930034 and 930037.and includes an air-cooled aftercooler, inter-stage separators, and safety relief valves on all stages. The compressor is skid-mounted with an integrated control panel for monitoring and automation, and it is designed for continuous-duty operation. Suitable for vehicle fueling stations or industrial applications, the unit ensures reliable performance with built-in protection systems.
