Pain Points of the Demand
After years of service, core components (valves, compressors, adsorbers) wear out and adsorbent performance degrades, reducing output and purity and causing frequent faults. Clients lack professional replacement technology, genuine spare parts, and face complex, time-consuming replacement procedures.
End-to-End Solution
Scheme Design
Comprehensive inspection determines replacement timing (e.g., adsorbent after 2–3 years, O₂ concentration dropping below 90%, or significant flow reduction). Customized plans specify component models, adsorbent specs (preferably high-efficiency lithium-based), replacement cycles, workflow, and cost — restoring performance to design standards.
Project Installation Guidance
Professional engineers supervise dismantling, replacement, and installation, ensuring component/adsorbent compatibility and proper parameter tuning post-installation.
Construction
Flexible, phased replacement around production peaks minimizes downtime. Old components and adsorbent are disposed of in compliance with environmental standards. During adsorbent replacement, vessels are cleaned and adsorbent densely packed per specification.
Acceptance and Delivery
Output, purity, and operational stability are verified, with operator training on post-replacement maintenance and a full warranty on replaced parts.
Equipment Operation and Maintenance
Post-replacement warranty with scheduled inspections addresses any issues, while long-term O&M guides daily maintenance to extend component and adsorbent life, backed by genuine spare parts supply.
