Class L includes high pressure gas compressors most used in CNG stations. Discharge pressure of these compressors is between 100 to 250 bar. These compressors can be designed and manufactured for custom flow rates and inlet pressures.

Features:
  • Oil-free non-lubricated gas pistons.
  • Full stroke-length distance pieces isolate the hydraulic drive from the gas cylinders.
  • Gas compressors work over a wide range of inlet pressures. In many cases inlet pressure regulators are not required.
  • Intensifiers are ideally suited for high pressures due to the simple geometry, slow operating speeds and in-line loads.
  • Long slow stroke and small dead volume in the compressor cylinders result in high volumetric efficiency.
  • Hydraulically driven intensifiers allow control of both discharge pressure and gas flow rate by controlling the hydraulic drive.
  • Gas pressure assists in the compression stroke improving the overall efficiency of the machine.
