Features and Advantages:

Reciprocating Gas Compressor are widely used in many industries related to the compression and supply of gas to consumers. Like oil and chemical industry, oil refineries and more. Various technological processes can include corrosive, inert, poisonous and explosive gases, which must be treated to a clean gas without impurities of oil.

Depending on the type of equipment, work with different gases, such as:

  • Natural gas,
  • Nitrogen,
  • Hydrogen,
  • Associated petroleum gas (APG),
  • Helium,
  • Methane,
  • Ethane,
  • Propane,
  • Chlorine,
  • Propylene,
  • Argon,
  • Various types of butane,
  • Carbon dioxide, etc.
Compressing package

Compressor units can be made on single frame design. With interstage devices and all necessary piping, placed on a single platform with a compressor.
Compressor units can be manufactured in the version "without lubrication of cylinders and oil seals"
The modern automation system of the compressor units guarantees the safety and easy use of the equipment.
Reducing the time of commissioning.

Application Field
