Vertical Horizontal Welded Heat Insulated Cryogenic Liquid Gas Dewar Cylinders
Description
Dewar flasks are small movable pressure cylinders that can be used to store and transport liquid gases. The overall volume is larger than that of gas cylinders and smaller than that of storage tanks.

Advantage
Cryogenic dewar overall solid and reliable quality, long heat preservation time, bring their own air supply system, the internal vaporizer can be continuous output gases (oxygen, nitrogen, azote) at room temperature, flow rate is as high as 9.2 m3 / h, maximum gas constant output pressure of 1.2 MPa (medium voltage) / 2.2 MPa (high pressure), fully satisfy the requirement of the normal gas. If the user's gas flow is large, multiple duval tanks or external carburetors can be used in parallel to meet the requirements of gas supply. By installing an external evaporator, the maximum output flow of a single dewar can reach 30m3/h.
Use caution
The first step in using a cryogenic dewar is to use high pressure metal hose to connect the line 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 does not meet the requirements for use, please open the booster valve, wait for a few minutes for the pressure to rise, and then it can be used when the requirements are met. 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 the cryogenic dewar.
