Cryogenic Stainless Steel Dewar Sizes Tank For Liquid Co2 O2 N2
Argon LNG
Description
A cryogenic dewar is a stainless steel pressure vessel with
ultra-vacuum insulation. It is specially designed for storing,
transporting and using liquid oxygen, liquid nitrogen, liquid argon
or carbon dioxide. It can be used for reliable and economical
transport and storage of cryogenic liquid gases, as well as for
on-site storage and supply of cryogenic liquid gases, with a wide
range of applications and economical safety.

Application
The Dewar is a super vacuum insulated stainless steel pressure
vessel designed for the storage, transport and use of liquid
oxygen, liquid nitrogen, liquid argon or carbon dioxide. These
containers are manufactured to standards for the economical
transport and storage of cryogenic liquid gases, as well as for
storage and supply of cryogenic liquid gases in a wide range of
applications.
Precautions
Dewar The first step is to use high pressure metal hose to connect
the pipe where the Dewar liquid valve is located to the evaporator.
Once the connection is confirmed, the fluid valve can be opened. If
the gas pressure to the company workshop does not meet the
requirements for use, please open the booster valve and wait for a
few minutes for the pressure to rise to meet the requirements for
use. When there is no liquid phase in the Dewar and the gas
pressure is only 5kg, it means that the gas in the Dewar has been
used up. Please close the liquid use valve and stop using it.
