Which company offers small oxygen generators?

Which company offers small cryogenic oxygen generators with an oxygen production capacity of around 100 Nm3/h? What is the highest purity level that can be achieved?
Companies like Hangyang and Chuan Kong are likely not interested in such a small device; Hangyang’s smallest low-pressure equipment currently has a capacity of 170 Nm3/h. The medium-pressure capacity is 150 Nm3/h (though it’s not widely used these days due to high energy consumption). You can inquire with some private air separation manufacturers; in the Hangzhou area, there are companies such as Fosda and Kaidé
Both Suzhou Oxygen Generator Factory and Suzhou Xinglu Air Separation Equipment Technology Development Co., Ltd. in Suzhou have mature products that can meet the requirements
There are many manufacturers of cryogenic oxygen generators; for example, in Suzhou. You can also search online. The purity level can be adjusted to meet your company’s requirements – 95% purity is likely achievable.
With such a small amount used, it would be better to have a storage tank and buy the liquid directly.
A production capacity of 100 Nm3/h is too low; there are many manufacturers of such equipment, in places like Suzhou and Handan, but the costs are too high. For cryogenic types, Shanghai Jiali has models with capacities of 1200 Nm3/h and 2000 Nm3/h in use; they seem to work well, but the production cost of the liquid is relatively high.
Cryogenic methods are not recommended as the cost is too high. If there are no special purity requirements, liquid oxygen can be purchased locally or a PSA system can be installed. I know that there is a company in Beijing named Minliding with a good PSA system, but it seems they don’t engage in cryogenic oxygen production. Their boss’s last name is Guo.
For this type of flow rate, cryogenic methods definitely cannot be used; PSA is an excellent alternative. I work in the field of PSA oxygen generators, and you can get in touch with me if you need one.
Hangzhou Fosda’s small air separation units operate at ultra-low pressure, with a pressure level of around 7 kilograms; they have low energy consumption, the oxygen purity reaches 99.5%, and currently such small air separation units are very inexpensive!
