Centrifugal units are distinguished by durability, economy, and the ability to regulate flow. Performance is very strongly influenced by changes in working pressure.
The KTK 12.5/35 compressor is used for compressing gaseous oxygen. The KTK productivity is 12 thousand cubic meters under normal conditions. Mainly, units of this type are used in chemical and metallurgical enterprises, and in other industries. Increasing gas pressure using a centrifugal compressor is used in air separation units.
Operation requires careful attention to the unit’s work and maintenance, as oxygen is highly flammable and can cause fire and explosion.



The 3TYS85+2TYS68 model, supplied by our company, surpasses the KTK-12.5/35 modification (produced by “Kazankompressormash”) in energy efficiency. The development is based on the manufacturing technology of Hitachi’s proprietary oxygen turbocompressor. Main parameters:
Operation of oxygen compression equipment requires the acquisition of compressors that fully meet safety requirements.
The 3TYS85+2TYS68 model is distinguished by the following design features that ensure safe operation:
RusGazKrio LLC not only sells compressor units from Hangzhou Oxygen Plant Group (China) but also conducts installation, commissioning, repair work, and service maintenance. We carry out modernization of oxygen-compressor shops with digitalization of supporting productions. We supply and develop comprehensive projects with automation systems and software. The equipment undergoes mandatory pre-launch inspection, complies with Russian and international regulatory documentation regulations, and is certified.
