Liquid Gas Supply

What Is Liquid Gas Supply?

We operate cryogenic air separation units at our own production centers. The liquid oxygen, nitrogen, and argon we produce is stored in cryogenic tanks and delivered to your facility via cryogenic tankers on a schedule that matches your consumption plan.
Upon arrival, the liquid is transferred into your on-site cryogenic storage tank. When needed, it passes through a vaporizer, converts to gas, and enters your pipeline network after pressure regulation.
A storage tank and a vaporizer are all you need on site. The rest, including production, transportation, and quality control, is handled entirely by Fengyun.​

How Liquid Gas Supply Works

1. Self-Owned Production Capacity
All liquid is produced by Fengyun's own air separation units — never outsourced or resold. Production capacity is directly matched to contracted volumes, ensuring your supply remains unaffected by third-party allocation.
2. Customized System Design
Storage tank volume, vaporizer specifications, and pressure regulation configuration are precisely selected based on your gas consumption curve and peak flow requirements.
3. Intelligent Level Management
Tank levels and pressure data are uploaded remotely. The system proactively triggers replenishment, eliminating the need for manual ordering.
4. Comprehensive Quality & Safety Control
Every batch undergoes factory-outlet testing, and every delivery is monitored throughout transit. On-site storage tanks and safety accessories are inspected on schedule, with fully traceable records.
