Atlas Copco’s CU/CT/CN is a complete series of oil-lubricated reciprocating compressors to meet your needs for high pressures up to 351 bar(a). Compact, with very low vibration levels and a sealed crankcase, CU/CT/CN compressors are the perfect solution for the compression of air, nitrogen, natural gas (NGV), hydrogen, noble gases and other industrial gases.


Customer benefits

  • High level of safety – A pressure-tight sealed crankcase ensures no emission of gases to the atmosphere, even gases with a low molecular weight.
  • High reliability – The CU/CT/CN trunk-piston technology offers field-proven ruggedness and reliability. Low compression ratios in the individual stages result in low thermal load for high reliability and high volumetric efficiency.
  • Easy installation – Very compact, frame-mounted and incorporating anti-vibration pads, CT/CU/CN compressors come as complete all-in packages that are simple to install without the need for foundations.
  • Low maintenance – An advanced maintenance concept ensures short downtimes and long intervals between maintenance.
  • A wide array of solutions – CU/CT compressors are available for inlet pressures from 1 to 19 bars, and 1- to 5 stage configurations. Discharge pressures are up to 350 bar for CU and CT, while CN units are available for inlet pressures from atmosphere to 1.35 bar(a) for pressures up to 350 bar. They are suitable for diverse applications: CNG car/bus refueling stations, H2 refueling systems, bottle filling, air-blast circuit breakers. A specific range of CU/CT compressors has been designed for seismic applications, for installation onboard ships, with closed loop freshwater/seawater cooling and marine adaptations. These machines are available for countries where ASME is not applicable.
