1. Aviation-grade Aluminum Alloy

To guarantee structural integrity under cryogenic liquid nitrogen conditions, the vessel's shell is constructed entirely from high-strength, lightweight, and corrosion-resistant aviation-grade aluminum alloy, meeting stringent performance requirements for cryogenic liquid nitrogen containers.

High Strength-to-Weight Ratio: Maintains structural integrity while minimizing weight, critical for portable liquid nitrogen dewar.

Corrosion Resistance: Oxide layer (Al₂O₃) provides inherent resistance to oxidation and chemical degradation, safeguard to your samples.

Cryogenic Toughness: Retains ductility and resists brittleness even at ultra-low temperatures -196°C for liquid nitrogen shock.

2. JOTUN^® Paint Finish

Globally renowned JOTUN^® paints (from Norway) not only deliver exceptional gloss and texture but also ensure eco-friendliness, non-toxicity, and long-term durability for reliable performance.

Superior Durability & Protection: Heavy-duty formulations protect assets in harsh environments and abrasion resistance.

Eco-Friendly & Safe: Complies with EU REACH, GreenGuard Gold, and LEED standards, non-toxic guarantee.

Aesthetic Excellence: Dirt-repellent surfaces retain pristine finishes and advanced pigments resist fading.

1. Forward-Thinking Design

Rooted in innovation and future-ready solutions, our design approach combines cutting-edge technology, user-friendly operation, fine appearance while retain the cryogenic perforance.

Modern Aesthetics: Treamlined, minimalist silhouette, SYDS series combine futuristic appeal with functional elegance.

Design Meets Performance: Wide-neek for large-quantity storage, slope and narrow-neck for transporation, our design is beyond beauty.

Multi-Layer Shielding: Super insulation materials require precise spacing - YDS series structural alignment avoids thermal bridging.

2. Automated Material Processing

Automated material processing equipments eliminates human error in critical dimensions and reduces material waste by optimizing cutting path which provide competitive advantages in cost lowering.

CNC Machining Centers: High-precision cutting, drilling, and milling of aluminum alloy to exact tolerances (±0.1mm).

3. Robotic Welding & Assembly

Liquid nitrogen containers require leak-proof, high-strength, and cryogenically stable welds to maintain vacuum integrity and structural reliability. Robotic welding is the preferred method due to its precision, repeatability, and efficiency.

Higher Precision – Repeatable weld paths with ±0.05mm accuracy.

Faster Cycle Times – Robots weld 3–5x faster than humans.

Lower Defect Rates – Near-zero porosity/cracks which is critical for vacuum retention.

Safer Operations – No human exposure to cryogenic hazards or UV radiation.

4. High Standard Vacuum Insulation

Vacuum insulation is the core technology enabling liquid nitrogen (LN₂) containers to maintain -196°C ultra-low temperatures with minimal heat transfer.

Multi-Layer Insulation: Multiple alternating layers of aluminized Mylar + fiberglass spacer achieve <0.1% daily evaporation.

High-Vacuum Sealing: Long-lasting evacuate air to 10⁻³ – 10⁻⁶ Pa and then seal using electron beam welding to prevent leaks.

Helium Mass Spectrometry Testing: Testing every product with automatic process ensures <10⁻⁹ mbar·L/s leak rate.

5. Quality Control & Testing Automation

To ensure safety, durability, and thermal performance, SYDS series undergo rigorous quality control QC and testing before labeling and packing.

AI-Powered Vision Inspection: Detects micro-cracks, porosity, or misalignments.

Helium Mass Spectrometers: Automated leak testing with sensitivity of 10⁻⁹ mbar·L/s.

Cryogenic Shock Testers: Subjects containers to rapid -196°C cycles to validate durability.
