Liquid Dewar Cylinder

Dewar is a stainless steel pressure vessel with super vacuum insulation, designed for storage, transportation and use of liquid oxygen, liquid nitrogen, liquid argon or carbon dioxide.

Product Detail

The inner and outer tanks of the product are made of 304 stainless steel, using a fully automatic CNC welding machine, and the automatic welding process on the outside of the bottle body, the welding is beautiful and reliable. The inside of the bottle body is fully automatic copper-tin brazing, and the welding is full and has high thermal conductivity. Each product will be tested twice for static evaporation rate, liquid filling test, air tightness test and cylinder pressure test to ensure the quality of our products

Specifications

  • Mainly used in storage and transportation of liquid oxygen
  • Adopted high multi-layer insulation method to ensure the low evaporation rate
  • Inner vaporizer provides a 10Nm3/h stable continuous gas
  •  Adopt the international CGA standard tie-in and all the valves installed imported from USA(Rego)
  • Unique design of damping ring meets the needs of frequent transportation.
