DSW Cryogenics has been a trusted manufacturer of cryogenic storage tanks since 2007. Our tanks are engineered in compliance with major pressure vessel codes and international standards, providing safe, reliable, and long-term storage solutions for industrial, laboratory, and medical applications.
Key Features & Technical Advantages
- High-Grade Materials: Stainless steel, aluminium, Inconel, and Monel ensure durability at extremely low temperatures.
- Double-Walled Construction: Inner vessel stores cryogenic liquid, outer vessel provides insulation and structural strength.
- Vacuum & Insulation Technology: Perlite or foam-filled vacuum layers reduce heat transfer and minimize boil-off.
- Boil-Off Minimization: Advanced insulation design reduces loss of stored cryogenic liquids.
- Temperature Stability: Circulation of LN₂ or LHe ensures precise temperature maintenance.
- Long-Term Storage: Ideal for gases, bio-samples, and other temperature-sensitive materials.

Vacuum-Insulated Tank Construction
Cryogenic liquid tanks feature a double-walled, vacuum-insulated design to maintain ultra-low temperatures and minimize heat transfer. The inner vessel is manufactured from cryogenic-grade stainless steel or specialized alloys, while the outer shell provides structural protection. Multilayer insulation within the vacuum space reduces thermal losses, and integrated pressure relief devices ensure safe and stable operation.
