S30408 Refined Polish

Each of our cylinder must strictly go throughdegreasing 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.




Cryogenic liquid cylinders have an inner container and an outer container with an insulated vacuum space between them .Any abuse(dents,dropping.tip-over,etc.)can affect the integrity of the containers insulation system.
DPL series containers will allow you to use a hand truck or hoist to handle these loads properly.Do not attempt to move these cylinders by any other means.While moving the cylinder,the following precautions should be observed

1.Never lay the cylinder on its side.Always ship,operate and store the unit in a vertical or upright position.

2.When loading or unloading the container from a truck,use a hand truck,lift gate,crane or parallel loading dock.Never attempt to manually lift the unit.

3.To move the container over rough surfaces,or to lift the container,attach an appropri-ated sling to the lifting points cut into the welded support posts,and use a portable lifting device that will handle the weight of the container and its contente
