[justin] : Why water bath vaporizer does not directly use the steam heating liquid nitrogen needs through steam heating water and then water heating liquid nitrogen?
Because water is the specific heat of the biggest material, can make the temperature stable, no fluctuations.
Water with the medium for heat, heat stable, with the words of steam temperature is too large, the pipeline is not good.

[justin] : Principle of PSA nitrogen machine？
PSANitrogen plant is designed and manufactured according to the pressure swing adsorption technology. Is a high quality imported carbon molecular sieve (CMS) as the adsorbent, using the principle of pressure swing adsorption (PSA) to produce high purity nitrogen.
Two adsorption tower is usually used in parallel, by the PLC control system for automatic operation of imported pneumatic valve, alternating pressure adsorption and decompression of regeneration, complete nitrogen oxygen separation, to obtain the required high purity of nitrogen.
[justin] : What kind of molecular sieve adsorbent is needed for the air separation equipment？
molecular sieve adsorbent 13X-APG
[justin] : What’s the warranty for the cryogeinc liquid storage tanks?
Our warranty is one year after shipment. Within one year, we will send broken spare parts at our cost upon request if it is proved to be our production defect. In fact, we rarely receive any spare parts request. If the tanks are maintained properly, they can be used for 15-20 years.
[justin] : What is your production standard? Can you manufacture your products under ASME standard?
Our products are designed, manufactured and tested as per reference standards of GB150, Safety technology supervision regulations of pressure vessels and some other reference Chinese standards.
Our company has obtained the A2 and C2, C3 Pressure Vessel Fabrication Certifcates ,Grade GC1 Pressure Pipe& Vessel Construction Certifcates, ISO9001 Quality Certificate, ASME Certificate and U Stamp. So, if you ask for ASME stamp, we are able to manufacture your products under ASME standard.
[justin] : How can we get liquid nitrogen?
Use Cryogenic air separation Unit can get liquid nitrogen, this Unit make air liquefaction and through rectification processes, Air will be separated to oxygen&nitrogen in the meantime can get part of liquid nitrogen as well.
[justin] : What are ways to get oxygen?
Green plant photosynthesis
Water electrolysis
PSA oxygen equipment
Cryogenic air separation plant
Heating potassium permanganate
[justin] : what is oxygen applications?
•Iron industry
•Combustion
Common applications include
•Fermentation
•Agriculture (fish farming)
•Welding and cutting
•Chemical Industry
•Glass industry
•Hospital applications
•Oxidation
[justin] : Should pay attention to when installing air separation plant the valve:
Valve installation should pay attention to air separation plant:
1) oxygen plant valve should generally be in the pipeline before installing location. Piping should be natural, the position is wrong not hard pull, so as not to leave the prestressed;
2) cold box temperature valve before position should be in the cold (such as in liquid nitrogen) do opening and closing test requirements, flexible and no jamming phenomenon;
3) air separation equipment of cold box, liquid valve should be configured to stem with the level of 10 degree tilt angle, to avoid the fluid flow along the stem, cold loss
