Which are the better manufacturers of steam ejectors in China?
Thread Content
Previously, the steam injectors we used were all imported. I’m not sure what the technical level is in China in this area – are there any good manufacturers?
We are using injectors from Hangzhou Huada Vacuum Equipment Co., Ltd., and they seem to work fine.
The Beijing Aerospace Power Research Institute, also known as Institute 11 of the First Academy of Aerospace, is the only entity in China that specializes in high-pressure injectors. Their products are much cheaper than imported ones, and their performance is guaranteed. If the original poster needs it, I can provide them with some relevant data later. :victory:
Thank you; please provide a copy with the samples and performance sheet. Do you also have the contact information and website addresses for 11 of them?

Beijing No. 11 Institute of the Aerospace Ministry seems to have done a good job; especially since all their designs are custom-made. For systems with the same specifications as 1830, the injectors they produce differ from each other, as there are still subtle differences in the process optimization for systems with identical production capacities； They also possess a complete vacuum system and the capability for process node balance analysis.
It’s not very clear in China. Abroad, there are GEA in Germany and Edward BOC in the United States. You can also ask around; perhaps foreigners have some new designs.
Some manufacturers in Nantong produce steam injectors
You import from that manufacturer, right? That’s what we need to import as well
The Beijing Institute of Aerospace Propulsion has done well; it possesses strong design capabilities as well as the necessary testing facilities. It is difficult for other domestic manufacturers to have such good conditions.
The best jetters abroad are GRAHAM
The main importers include Koerting Hannover AG (Koerting) from Germany, GEA, as well as Graham from the United States.
We have used injectors from a company in Shaanxi named Xiangyang Vacuum; so far, they have very low energy consumption and their prices are also quite reasonable
Imported German GEA or Croer Reynolds are also quite good.
