About Us — International Oil-Free Oxygen Compressor Manufacturer
Seven decades of reciprocating compressor engineering. ISO 9001 certified. API618 and EIGA IGC 10/07/E compliant. Supplying Russia, CIS and 30+ countries worldwide.
Who We Are — A Manufacturer Built on Precision and Reliability
We are a specialist manufacturer of oil-free reciprocating piston oxygen compressor machines, with a manufacturing history spanning more than 70 years. Our product range covers single-unit flow rates from 2 to 500 Nm³/min and discharge pressures from 0.1 to 32.0 MPa — one of the broadest configuration ranges available from a single compressor manufacturer globally.
The company was established in 1951, initially as a state machinery enterprise under direct supervision of the Ministry of Machinery Industry. Over the following seven decades the organisation transitioned into a fully independent manufacturing entity, retaining its core technical foundation in reciprocating piston compressor engineering while expanding across multiple gas domains. Foundational product lines received China National Silver Quality Awards, the highest state-level recognition for manufactured products.
Today we supply oxygen compressor machines to steel mills, hospital networks, chemical plants, LNG facilities, and air separation units across more than 30 countries including Russia, Kazakhstan, Uzbekistan, the United States, and Germany. Our products are designed and manufactured to API618 international standard and EIGA IGC 10/07/E oxygen service requirements, with ISO 9001 quality management certification maintained continuously.
Our History — Seven Decades of Compressor Engineering
From a state machinery enterprise founded in 1951 to an international oxygen compressor machine supplier — a timeline of key milestones.
Founded as a state machinery enterprise under the Ministry of Machinery Industry. Core product: reciprocating piston air compressors.
Expanded into process gas compression — coal gas, blast furnace gas, and coke oven gas compressors for the steel industry.
Launched first oil-free reciprocating air compressor series. Foundational models 3L-11/7 and 4L-22/7 later awarded China National Silver Quality Medal.
Began development of dedicated oxygen compressor product line — applying oil-free cylinder engineering specifically to oxygen service safety requirements.
PSA and VPSA oxygen system compressors introduced. Supply partnerships with air separation plant operators established.
First international export orders fulfilled. API618 standard compliance adopted across the oxygen compressor range. ISO 9001 certification obtained.
Hydrogen compressor and CO₂ compressor product lines launched. Supply to LNG plant operators for BOG and mixed refrigerant compression. Russia and CIS supply programme established.
800+ validated compressor configurations across oxygen, nitrogen, hydrogen, and speciality gases. Active supply to 30+ countries. Full EIGA IGC 10/07/E compliance.
Certified for Global Industrial Standards
Every oxygen compressor we manufacture adheres to the strictest international safety and quality protocols, ensuring reliable operation in heavy-industry applications worldwide.
End-to-End Manufacturing Excellence
From raw material processing to final performance verification, our fully integrated manufacturing facilities ensure uncompromising quality control at every stage of the compressor lifecycle.
Precision CNC Machining
Critical core components are manufactured in our dedicated CNC centers, guaranteeing micro-level tolerances and superior mechanical integrity.
Oil-Free Assembly Protocols
Oxygen compressors are assembled in specialized, contamination-free zones strictly adhering to EIGA guidelines to ensure absolutely zero hydrocarbon presence.
Full-Load Performance Testing
Every unit undergoes rigorous thermodynamic and mechanical test runs, closely monitored for vibration, temperature, and efficiency.
Warehousing & Global Logistics
Finished units are treated with anti-corrosion coatings and robust export packaging, ensuring safe deployment to global operational sites.
Our manufacturing capabilities are supported by a massive and highly specialized equipment inventory. The facility operates 362 metal and machining machine tools, alongside 103 sheet metal and welding units. Heavy components are processed through 43 casting machines and 20 advanced heat treatment systems. To maintain strict quality standards, we utilize 55 specialized physical, chemical, and analytical testing devices, supported by an internal logistics network of 82 hoisting and transportation units.
Rigorous Certification & Validation Process
From raw material procurement to final dispatch, every oxygen compressor undergoes a strict, multi-stage certification protocol ensuring absolute safety and compliance with international standards.
Raw Material Certification
Incoming materials undergo spectrometric analysis and ultrasonic flaw detection (NDT) to verify metallurgical integrity before machining begins.
Component & Dimensional QC
Machined components like cylinders and crankshafts are verified using precision Coordinate Measuring Machines (CMM) to guarantee micro-level design tolerances.
Oxygen Service Auditing
All gas-contacting parts undergo specialized degreasing. Hydrocarbon absence is strictly verified using ultraviolet (UV) black-light inspection prior to assembly.
Factory Acceptance Test (FAT)
The fully assembled unit undergoes a comprehensive mechanical run and performance test under load, with detailed diagnostic reports generated for client sign-off.
