Self-pressurized cryogenic vessels
Companies large-scale and variety
as many as models complete, low prices
Daily boiling-off rate (%):≤1.4
We provide a range of Self-pressurized cryogenic vessels for liquid nitrogen use. This type of dewar uses a valve to divert liquid to a boiling coil inside the vessel, which increases the pressure so that liquid can be forced out. This range is ruggedly built and is ideal for transportation of liquid nitrogen by road.
*Widely used supplementary and transportation of liquid nitrogen,liquid oxygen,and liquid argon containers*Together with the devices of laboratory and electronic instruments.
(1). Filling liquid:
While the vessel is filled from inlet/outlet liquid valve, please open the vent value at first; connect the flexible metal hose to the inlet/outlet liquid valve; open the inlet/outlet liquid valve, through which the liquid medium may be filled; when the liquid filling is carried out, the inlet/outlet liquid valve shall be switched off.
While you use this vessel to store any liquid medium, please close the inlet/outlet liquid valve and the pressure increasing valve;
When you use this vessel to transport any liquid medium, .please close the inlet/outlet liquid valve and the pressure increasing valve; and the vent valve shall be switched on.
The package box base shall be paved under the container seat ring and the container shall be fixed reliably with the truck.
(4) Liquid supply:
If you want to supply liquid from the vessel, please operate according the following procedures:
(1). Close the vent valve;
(2).Open the pressure increasing valve;
(3). View the pressure gauge;
(4). When the pressure is increased to 0.05 MPa (0.5kg/cm2), open the inlet liquid valve, namely, the liquid may be supplied continuously.
Warranty:The warranty is generally 5 years vacuum, during which the replacement of broken components are free.
