Certified oil-free

Securing your process with the best possible air and gas quality, oil-free technology meets the stringent ISO Class Zero standard. Oil-free delivery is not only important when gas comes into contact with consumable end products; it also eliminates the adverse effects that oil can have on your processes and equipment.

Fully adaptable to your application needs

We can meet your gas composition compatibility and inlet pressure requirements with fully customized parts and materials. Choose components (valves, piston rod packings, cylinders) according to your gas type and humidity content, or select a standardized setup.

Handling many gases and applications

Meet one of the most versatile compressors in the industry: HX/HN compressors handle air, nitrogen, helium, hydrogen, argon, CO/CO2, biomethane, natural gas, compressed natural gas for grid injection etc

24/7 compressor operation

Boosting your uninterrupted productivity, HX/HN compressors can work efficiently and cost-effectively under difficult site conditions with minimal maintenance and long overhaul intervals

Up to 8 000 hours/year service-free

Turn to a machine that gets the job done without fail. With a horizontal balanced opposed design that is safe and produces less vibration, HX/HN compressors several thousand hours per year without service intervention. Low piston speed and low inter-stage temperatures also preserve the inner parts of the machines, drawing from API 618 guidelines

Technical description HX and HN Series oil-free piston compressors for air and gas

Industrial air and gas applications

HX and HN compressors are at work in power plants, oil and gas sites, chemical plants, and industrial processes around the world. Powered by an energy-efficient horizontal balanced opposed design, our versatile HX/HN compressors can have many faces. Handling gases such as air, nitrogen, CO/CO2, methane, hydrogen and argon, they play the part of:

  • fuel gas booster
  • high pressure air supply for air separation units
  • nitrogen booster in many industries like metal, food and beverage

Meeting international standards

HX and HN compressors are certified according to major international standards including:

  • CE/PED
  • ASME
  • SQRL
  • GOST
  • IEC/CE
  • UL/CSA
  • ATEX Zones 2, 3
  • PED module D & H
  • other codes or standards on request

Oil-free whatever the conditions

Oil-free compression with PTFE piston rings and long distance pieces safeguards gas quality. That’s an important asset, since even the slightest contamination of oil is unacceptable and could lead to high risks in many applications. HX/HN compressors work under strenuous conditions in outdoor, indoor, refineries, deserts (high inlet temperatures) and sandy environments.

Adjustable flow rate

To ensure maximum flexibility in your operation, a variety of regulation systems, including optional variable speed drive, valve load-unload mechanism adjust the flow rate according to the actual utilization of the machine. What’s more, our experts are here to help you choose compressor options to meet your specific needs.
