Content

VIE (Vacuum Insulated Evaporator) tanks .
The gas pressure inside the VIE tanks needs to be maintained at a constant level and if the pressure drops too much, the regulator that controls the pressure in the pipework will not work properly. To prevent this, when the pressure falls below a threshold, the valve opens and allows oxygen to flow through the heat exchanger fins. This evaporates the oxygen and raises the pressure in the tank.

If the usage is too low, the temperature will rise until the safety valve opens. When this happens, the VIE (Vacuum Insulated Evaporator) tanks will vent the gas. This is a normal part of the function of these tanks

Adiabatic heat preservation: Cryogenic storage tanks have excellent adiabatic heat preservation performance, which can effectively reduce heat conduction and evaporation loss. Through the use of high-performance insulation materials and insulation layer, the tank can keep the temperature of the storage medium stable, reduce energy consumption and improve storage efficiency.

Insulation and safety protection of cryogenic tanks

Oxygen is a strong combustion-supporting agent, which can intensify combustion or even cause an explosion in an oxygen-rich environment. No combustibles are allowed around the 4 equipment containing liquid oxygen (oxygen). All parts in contact with liquid oxygen (oxygen) should be treated with no oil and confirmed Its compatibility with oxygen.
