Pain Points of the Demand
Cryogenic ASU has high CAPEX, long construction periods, high energy consumption, and high O&M costs. Clients want to replace it with a cost-effective alternative while maintaining purity and stability.

End-to-End Solution
Scheme Design
We survey oxygen demand (purity, flow, pressure) and working conditions, comparing cryogenic and VPSA economics. A customized VPSA replacement solution is designed with efficient, energy-saving equipment — VPSA comprehensive power consumption can reach as low as 0.29 kWh/Nm³. Example: At Yongyang Special Steel, VPSA replaced the “cryogenic + purchased LOX” model, significantly reducing CAPEX and OPEX.
Project Installation Guidance
Engineers direct VPSA installation, pipe retrofitting, and electrical configuration, ensuring seamless tie-in with existing production piping with minimal impact on operations.
Construction
Modular construction shortens the schedule by 50%+ compared to cryogenic ASU, with careful coordination of old equipment dismantling (if any) and new equipment installation to ensure uninterrupted oxygen supply.
Acceptance and Delivery
Output, purity, energy consumption, and operational stability are verified — delivering superior cost-performance over cryogenic ASU. Full operator training and documentation ensure smooth transition.
Equipment Operation and Maintenance
Long-term service with parameter optimization further reduces energy consumption. O&M costs are typically 30%+ lower than cryogenic ASU, delivering continuous savings.
