Poorly Made in China. Compressors. Post #2 – Project #1. Baku, Azerbaijan

What Can Go Wrong with a New Chinese Compressor?

  • Why can a brand-new compressor from China be impossible to commission after delivery?
  • What can you discover inside the equipment after a complete disassembly?
  • Is it possible to build a reliable compressor from Chinese components that will actually work?
  • And where does simply buying equipment end and real engineering work begin?

In this article, we share a real project in Baku, Azerbaijan: compressor disassembly, the problems we discovered, modifications, commissioning, and our experience working with Chinese components.

Spoiler: the problem is not always the Chinese components themselves. What matters much more is who turns those components into a complete compressor, how they do it, and according to what technical requirements.

How to Damage a High-Pressure Compressor by Spending Just €300

Date: Views: 27

Can you seriously damage a high-pressure compressor worth hundreds of thousands of euros simply by using the wrong oil?

How can a €300 consumable lead to a major overhaul and weeks of equipment downtime?

And why are there no “small details” in high-pressure compressor maintenance – even when it comes to oil, component cleanliness, or an ordinary filter?

How to Prepare a Technical Request, or How to Tell a Professional from a Dilettante

Date: Views: 43

How can you tell a true professional from someone who is simply putting in eight hours at work?

Why is the phrase “But you didn’t order that” one of the biggest warning signs of a bad supplier?

How do you prepare a technical request if you don’t know all the technical details yourself?

And how can you tell, before buying the equipment, who will actually solve your problem — and who will leave you dealing with problems for years?

Let’s talk about that…

This post is about oil-lubricated high pressure compressor with dryer for hydrogen (H2).

Manufacturer is Gardner Denver (CompAir Reavell in the past).

Yes, it’s not diaphragm compressor.

But, as I wrote before, I would like to share my experience and show to you some examples from my life about high pressure compressors for hydrogen.

The main principles of installation for piston compressors are the same as for diaphragm compressors.
