1. Excellent insulation performance, extending storage time
Features advanced vacuum multilayer insulation technology, achieving an ultra-low daily evaporation rate of <1.5%. This extends the liquid holding time by up to 30% compared to conventional cylinders, significantly reducing product loss and operational costs.
2. Full 304 stainless steel structure, sturdy and durable
Constructed entirely from grade 304 stainless steel, offering superior corrosion resistance and durability. The robust construction ensures a long service life of 15+ years with minimal maintenance requirements, even in demanding environments.
3. Reinforced structure and unique shock-absorbing base
The cylinder body is reinforced with protective rings, increasing impact resistance. Paired with a specially designed shock-absorption base, it reduces vibration transmission by over 40%, safeguarding the internal vacuum integrity and extending the product's service life.
4. Upgraded electronic level gauge, precise and easy to use
Equipped with a digital LCD display that provides real-time liquid level and pressure readings with an accuracy of ±1.5%. This eliminates the guesswork associated with traditional mechanical gauges and allows for remote monitoring from up to 100 meters away.
5. Optimize filling design to save time
The optimized top valve assembly and increased fill port diameter enable a 20-30% faster filling speed, reducing typical filling operations from 30 minutes to approximately 20 minutes, thereby enhancing workflow efficiency.
6. Strict supply chain and quality control to ensure safety
Core components are sourced from ISO 9001 certified suppliers. Our automated manufacturing and a 3-stage quality inspection process ensure a product failure rate of less than 0.5% within the warranty period, guaranteeing exceptional safety and reliability.
