Custom Nitrogen & Oxygen Generation Plants Built By Our Factory
PSA and VPSA gas generators, cryogenic air separation units from 50 to 80,000 Nm³/h, storage tanks and cylinder-filling solutions - engineered, fabricated and tested in our own 100,000 m² workshop, delivered to 20+ countries.
Choose Your Separation Technology
Three proven routes to on-site gas - adsorption, cryogenic small-scale, and full cryogenic ASU. Not sure which? Send your flow and purity; an engineer picks the cheaper plant, not the pricier one.
VPSA Oxygen Plant
When your oxygen demand passes the point where PSA skids stop making sense, vacuum does the regenerating

One Factory, Whole Plant Scope
- Everything under one roof - towers, cold boxes, tanks and cylinders fabricated in our own A1/A2 licensed workshops, not brokered from trading companies.
- Ultra-low-pressure 0.43 MPa process and 8.5 MPa internal-compression flows from 36 patents of accumulated ASU engineering.
- Nearly 300 ASU sets delivered, over half of them 1,000 TPD-class and above; 18 units at the 30,000 class, 3 at the 50,000 class.
- Engineers answer inquiries - flow, purity and pressure in, a sized proposal back within 24 hours.
- BOO option - we can even finance and operate the plant while you simply buy the gas.
The Rest Of The Gas Chain
Generation is half the story. We build the tanks, cylinders and compressors that store, move and re-inject your product gas.
