Re: Before making quotation to you, please kindly specify the following information:

1) Capacity:

2) Medium (LO2,LN2,LAR or LCO2?):

3) Working pressure:

2. Q: What is the material of vaporizer?

Re: The main material of our vaporizer is Al+SUS304.

3. Q: What’s the Working Theory of vaporizer?

Re: The working principle of air-heated vaporizer is to heat liquid by air temperature, not use electricity. As we know, the normal air temperature is much higher than the temperature of liquid oxygen. Once the heat exchange area reaches a certain level, the liquid oxygen will change into gaseous oxygen.

4. Some low quality air heated vaporizers have many disadvantages:

1).   The aluminum is low quality with low intensity.

2).   Less fins than good one. And the fin is very thin, so that will decrease the heat exchange effect. When it is freezing, the fin will be bended by the ice.

3).   Welding gap is not sealed well, which cause gas leakage.

4).   The thickness is not even, causing working intensity and heat exchange.

5).   The stainless steel pipe is not thick enough and welding craft is not so good.

6).   Non- destructive test isn’t done or not enough, which will make gas leakage problem.

7).   After producing, we use nitrogen gas to test leakage, and use water pressure to test intensity. Some factories cancel this process in order to decrease the cost. Therefore, their customer is the victim.
