Polished Helium Vessel, Automation Grade : Automatic

Liquid helium demands exceptional containment solutions to preserve its ultralow temperature (~−269 °C) and prevent rapid boil-off. Our advanced containers and transport systems ensure safe, efficient, and reliable handling for research, medical, industrial, and space-flight applications.

1. Ultra‑Low Temperature Performance

• Multi-layer, vacuum-superinsulation combined with radiation shields and exhaust-gas cooling reduces heat ingress, minimizing evaporation & enabling long-term helium storage.

2. Robust Pressure & Safety Management

• Integrated vacuum seals, pressure-relief valves (typically ~70 mbar), and safety attachments regulate internal pressure reliably.

• Self-pressurizing systems use vaporization gas to aid extraction and maintain pressure without external sources.

3. High-Integrity Construction

• Crafted from corrosion-resistant stainless steel or low-temperature alloys to withstand stresses and cryogenic exposure

4. Range of Sizes & Certifications

• Transport vessels: small dewars (30–1,000 L) up to mobile units (~250–380 L) and ISO-frame containers (e.g. 41,600 L) for road & maritime use

5. Optimized Mobility & Handling

• Many units include stable, lockable castors or forklift-friendly ISO frames for easy movement .

• Internal suspension systems help minimize stress during transport via road, rail, air, or sea .

6. Economical & Sustainable Operation

• Exceptionally low evaporation rates (~0.9–1.3% per day), significantly reducing helium loss and operating cost.

• Efficient use of latent boil‑off gas for insulation cooling reduces reliance on external cooling systems .
