Dewar:
Our Dewar is mainly used in storing and transporting liquid oxygen, liquid nitrogen, liquid argon, LNG and liquid carbon dioxide and is widely used in many fields such as electron, scientific research, chemical industry, welding and LNG supply etc.
Features:
1.High gas-storing capacity, low use and storage pressure, good safety, no high-explosive danger.
2.Good appearance, clean, no pollution.
3.Adopting high vacuum multi-layer winding insulation system to insure low evaporation rate.
4.Equipped with built-in gasifier which can automatically provide stable and continuous gas with capacity of 10Nm3/h.
5.Gas-saving device gives priority in use of gaseous-phase overpressure gas.
6.Adopting internationally accepted CGA joints and imported valves.
7.The unique design of the shock-absorbing ring can suit frequent transportation requirements.
