175L Horizontal Cryogenic Gas Dewar Cryogenic Liquid Storage Vessel For LNG
Products Description
The 175L Cryogenic Dewar Tank is a high-vacuum insulated pressure vessel engineered for the storage and transport of liquid nitrogen (LN₂), oxygen (LOX), argon (LAr), carbon dioxide (LCO₂), and LNG. Constructed from high-strength aluminum alloy or stainless steel, it features multi-layer insulation (MLI) and high-vacuum jacket technology with a static evaporation rate as low as 0.87–1.0 L/day, delivering reliable long-term performance at temperatures approaching -196°C for biobanking, industrial gas distribution, and laser cutting assist-gas applications.
