5000L Liquid CO2 Cryogenic Tank Supplier for Industrial Use

Product introduction of Liquid CO2 Cryogenic Tank

This liquid CO2 cryogenic storage system adopts a double-layer cylindrical structure combining stainless steel inner tank and carbon steel outer shell. The interlayer is filled with expanded perlite and maintained under high vacuum conditions to achieve superior thermal insulation. Designed for industrial-grade gas storage, it supports efficient containment of liquefied carbon dioxide under low temperature conditions ranging from -196°C to -50°C.

The 5000L effective volume configuration makes it suitable for medium-scale industrial use, offering stable pressure control, reduced evaporation loss, and centralized operation capability.

Working principle

Step 1. Liquid CO2 is filled into the inner stainless steel tank under controlled pressure
Step 2. Double-layer structure isolates external heat using vacuum and perlite insulation
Step 3. Adsorbent materials stabilize interlayer vacuum performance for long-term efficiency
Step 4. Pressure is regulated within 0.2–3.0 MPa working range automatically
Step 5. Stored CO2 remains in stable cryogenic state at -196°C to -50°C
Step 6. Controlled discharge system delivers gas or liquid CO2 as required
