It is necessary to distinguish between good and bad, I think only the configuration of the equipment is not the same.
You sign the contract of the technical agreement can be communicated in more detail on it
1, the core - carbon molecular sieve - imported Japanese Takeda carbon molecular sieve and domestic CMS series carbon molecular sieve price difference is very large
2, pneumatic angle seat valve - the use of German Bauder pneumatic valves, solenoid valves and domestic valves and another big difference
3, electronic control - Siemens, ABB and so on and domestic valves, and so on and so on. -Siemens, ABB, etc. and Chint's price is certainly not the same
So it mainly depends on your technical parameters of the equipment configuration requirements are not exhaustive enough.
A price is a good thing, it should be well understood!
The hard work of coding, but also hope to adopt!
