ABC has manufactured many reciprocating compressor units for a wide range of industrial gases: nitrogen, argon, hydrogen, helium, carbon dioxide, natural gas... up to 150 bar and up to 600kW.

In this sense and for more than 30 years, ABC COMPRESSORS has supplied gas compressor sets for the separation, transport and storage of air separation gases (PSA or VPSA, membranes or similar), for the reformation of hydrocarbons or natural gas, and for the treatment of syngas, among others.

These reciprocating compressor packages have the following features:

      • ·  With belts or with direct coupling, cooling towers or air coolers are available.
      • ·  Choice with low and medium voltage panels.
      • · Useful gas compressor for ATEX/NEC/NEMA classified areas or for sets under European Directive 2006-95/NEC non classified areas.

Thus, each gas compressor is manufactured made-to-order, perfectly adapted to the requirements of each installation, ensuring the reliability, energy efficiency and robustness.

In consequence, ABC COMPRESSORS supplies the best reciprocating compressor that combines the best technological features in the market.

Purification of saturated CO₂


Country Portugal Stroke (mm) 150 Year 2012 Speed (RPM) 740 Compressor model 3EHA-6-TER-GT Capacity (Nm³/h) 1.078 Gas Carbon dioxide Motor (kW) 250 Number of stages 3 Suction pressure (Bar) 1,1 Number of cylinders 6 Discharge pressure (Bar) 35,0 Cylinder sizes (mm) 2x310/2x160/2x95

Additional comments

This is a wet carbon dioxide compressor for one of the most important industrial gas producers worldwide, which required the pumping of 2.160 kg/h of wet CO2 to help achieving a high purification of the gas. The project consisted on the delivery of a 3EHA-6- TER-GT package (3 stages and 6, non-lube, double acting cylinders), coupled to a 250kW motor controlled by a frequency converter. All accessories in contact with gas (dampers, separators, coolers and pipes) were made out of stainless steel. The main challenges were the high flexibility to adapt to customer´s specifications and the tough delivery time (5 months since PO to site).
