Description

Technical description reciprocating gas compressors HX and HN

Industrial air and gas applications

HX and HN high pressure reciprocating gas compressors handle compression solutions in power plantsoil and gas siteschemical plants, and industrial processes around the world. Powered by an energy-efficient horizontal balanced opposed design, our versatile HX/HN gas compressors can have many faces. Handling gases such as air, nitrogen, CO2, methane, hydrogen and argon, they play the part of:
 

  • fuel gas booster
  • high pressure air/nitrogen supply for air/nitrogen separation units
  • nitrogen booster in many industries like metalfood and beverage
     

Our flexible HX/HN design can be used for a wide variety of applications and industries.

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 high pressure gas compressors work under strenuous conditions in outdoor, indoor, refineries, deserts (high ambient temperatures) and sandy environments.

Adjustable flow rate

To ensure maximum flexibility in your operation, a variety of regulation systems, including optional variable speed drive (high variable large scale between 40-100% of the flow), valve load-unload mechanism adjust the flow rate according to the actual utilization of the machine and bypass system (pressure control valve). What’s more, our experts are here to help you choose compressor options to meet your specific needs. 

Benefits

Technical benefits

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.

More on Class 0

Fully adaptable to your application needs
We can meet your gas composition compatibility and inlet pressure requirements with fully customized parts and materials. We are compliant with the 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 reciprocating compressors in the industry: HX/HN compressors handle air, nitrogen, hydrogen, argon, CO2, biomethane, natural gas, compressed natural gas for grid injection, etc
24/7 compressor operatio
Boosting your uninterrupted productivity, HX/HN piston gas 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 gas 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
