Frosting problem in liquid nitrogen vaporizer
Thread Content
We currently use liquid nitrogen that is vaporized for our needs. Since the installation of the equipment, there has been a problem of frosting on the vaporizers. We have now added an additional vaporization unit, with the two vaporizers operating in series. However, the frosting problem persists. I’m wondering whether it would be better to switch to using the two vaporizers in parallel. I would appreciate any suggestions from everyone; thank you!
To address this issue while maintaining the same gasification capacity, it is necessary to use two gasifiers in parallel. Switch every 5 to 6 hours.
Thank you! Do you mean that if both are turned on at the same time, even in parallel, frost will form?
We used to have only one unit; when a large amount of gas was used, frost would form. As long as the frost covered no more than half of the surface, it did not affect usage. It is recommended to use one and keep another as a backup, switching between them as needed
We also have this device, and frost formation seems inevitable. We use multiple air bath vaporizers in parallel; usually one or two are employed, and it’s sufficient to switch them at regular intervals!
What problems will arise if frost forms? Will the heat exchange be poor later on? Will it affect usage?
If frosting is severe, it will reduce the vaporization effect； This could lead to low-temperature liquid nitrogen entering the pipelines and equipment ； Due to low temperatures, pipelines and equipment made of non-special materials can be damaged; over time, the consequences will be……
