CU Series Heavy-Duty Gas Compressors
Our CU series oil-lubricated heavy-duty high-pressure gas compressors feature a compact design, robust functionality, and reliable performance, enabling efficient compression of air, nitrogen, natural gas, hydrogen, helium, and other industrial gases.
Did you know?
With their low operating temperatures and minimal number of valves, the CU-series heavy-duty compressors help streamline your process. By eliminating leaks from packing seals, they can significantly reduce your gas costs.
Technical Description of the CU Series High-Pressure Gas Compressors
Our CU series heavy-duty compressors offer quick installation and minimal maintenance requirements, making them ideal for a wide range of high-pressure applications, including:
･ NGV refueling station
･ Hydrogen refueling system
･ Bottling
Air‑arc‑extinguishing circuit breaker
Can handle many typical industrial gases.
Our CU series high-pressure compressors embody decades of experience in industrial gas processing, enabling you to handle a wide range of common industrial gases, including:
･ Air
･ Nitrogen gas
･ Helium gas
･ Hydrogen gas
･ Natural gas
• Carbon monoxide
• Carbon dioxide
･ Noble gases and gas mixtures
Secure and intact
To ensure that operators can handle a wide range of industrial gases safely and without contamination, the CU‑series gas compressors feature pressure‑sealed crankcases, which both prevent gas leakage from the compressor and protect the gas from being contaminated by ambient air. We offer a complete portfolio of compressor packages to meet the diverse requirements of natural gas vehicle (NGV) refueling stations. To achieve the specific inlet pressures needed for your application, we provide both standard‑design and custom‑designed models. For reliable, long‑lasting operation, the CU‑series heavy‑duty gas compressors minimize the number of valves and operate at lower valve temperatures, while also incorporating a crankshaft‑driven oil pump, cooling fans, and a single‑acting compression design with cylindrical pistons.
Decades of experience in CNG station cooperation
For decades, Atlas Copco has established a strong global reputation in the field of high-performance compression systems for CNG refueling stations. Our compressors and accessories deliver exceptional reliability, safety, and energy efficiency, meeting the demanding requirements of your CNG refueling infrastructure.
Meets international standards
We comply with the international standards ISO 9001, ISO 14001, and OHSAS 18001. We employ lean design and agile manufacturing methodologies, striving to support our global customers with high‑quality products. This includes the high‑pressure safety connectors for the CU series gas compressors, which have achieved “zero defects” certification.
Technological Advantages
･ High pressure, high safety
Our CU-series high-pressure compressors are protected by a pressure-sealed crankcase, which prevents gas leakage into the atmosphere even when handling gases with low molecular weights, and can deliver pressures of up to 480 bar(a).
• Customizable options
Choose the configuration that best suits your process. The CU series compressors offer inlet pressures from 1 to 19 bar, with compression stages ranging from 1 to 5, and discharge pressures up to 480 bar.
･ Particularly suitable for CNG refueling
The CU series piston compressors have earned the trust of numerous CNG refueling station operators thanks to their safety and reliability. We can support your CNG applications with specially designed compressor units and a complete range of accessories, all of which comply with European or U.S. standards: NEC/UL Class I, Division 2, Group D explosion‑proof certification.
• Plug-and-play, quick installation
Ready for immediate deployment. To ensure quick and convenient installation, these high-pressure compressors are mounted on concrete platforms and delivered as complete, integrated units, making installation straightforward without the need to construct a foundation.
• Low maintenance, low cost
Reduce your maintenance costs. The CU-series heavy-duty compressors incorporate advanced maintenance concepts, ensuring shorter downtime and extended service intervals. To deliver reliable performance and significantly extend uptime, our cylinder‑type piston technology boasts field‑proven robustness and offers lifecycle costs that are among the lowest in the market.
• Oil-lubricated reciprocating compressors with pressures up to 480 bar (a)
Our CU series gas compressors are complete oil-lubricated reciprocating compressors, delivering pressures of up to 480 bar (a), and are ideally suited for highly demanding compressed air and gas applications.
