II. Core Product Advantages

1. Large‑scale Atmospheric Storage, Stable Gas Supply

• Large‑capacity storage: Single unit 5~300m³, multiple tanks can be installed in parallel for large‑scale gas supply in industry, peak‑shaving stations and LNG fuelling stations.
• Economical atmospheric operation: Near‑atmospheric operating pressure greatly reduces compressor power consumption and daily operating cost, ideal for 24h continuous supply.

• High‑efficiency insulation: High‑vacuum multi‑layer or vacuum powder insulation with high vacuum and thick insulation layer. Static evaporation rate ≤0.3%/day, far below industry average, minimizing LNG loss.
• Ultra‑low temperature resistant material: Inner tank made of austenitic stainless steel, resistant to -196℃, stress corrosion and fatigue for safe long‑term storage.

• Low‑temperature resistant design: Outer tank made of EN/Q345D/E cryogenic steel, usable down to -40℃, ideal for northern forests, mines and frigid zones.
• Stable foundation: Concrete pile foundation prevents tank settlement caused by frozen soil thawing, ensuring stable long‑term operation.

• Multiple safety interlocks: Equipped with safety valves, emergency shut‑off valves, overflow prevention and leakage detection for automatic protection and alarm under overpressure, overtemperature or abnormal level.
• Safe and durable materials: Corrosion‑resistant inner tank, impact‑resistant outer tank, meeting pressure and safety requirements at -196℃ and in corrosive environments.
• Authoritative certifications: A1 Class Pressure Vessel Manufacturing License, certified by national special equipment inspection, complying with GB/T 18442 and other standards.

• Modular installation: Single or multiple parallel tanks, expandable as needed.
• Strong function expansion: Can be equipped with BOG recovery system, ambient air vaporizer, pressure regulating and metering skid, directly upgraded to LNG fuelling station, industrial gas supply station or city peak‑shaving station.
• Easy maintenance: Overhaul and test ports reserved, simple daily maintenance, no frequent shutdown required; service life over 20 years.
