| Note: The maximum filling capacity is calculated based on the boiling point of the liquid under normal atmospheric pressure. The actual filling capacity is affected by the liquid temperature and pressure inside the container, which is about 95% of the maximum theoretical filling capacity, and about 90% for natural gas. | |||||||||||||||

S30408 Refined Polish Each of our cylinder must strictly go through degreasing and refined polish. | Digitail level gauge Optional we provide digital level gauge for option, which is show by precision percentage. | Anti-Shock Rubber Cushion The thicken rubber cushion can greatly prevent the inner container from any sudden shock and bufferthe impact. |
25 layers of Vacuum insulated quilt We use 25 layers of mutiple thermal insulated quilt to ensure the vacuum effectiveness. | Protective ring. Each of our cylinder has two protective rings to protect the brass vaporizer coils and pressure built coils from any deformation | Firm Foundation Structure. Our DPL-450L&410L serials are all fabricated by bolts and nuts with strong frame foundation. |
