Experience with Shenyang Yuanda equipment
Our serviced equipment list includes Shenyang Yuanda hydrogen make-up compressors K-1101-A and K-1101-B, model P3.5-1.42/22.3-32.06, together with reciprocating compressors К-201 А/В (Р5.5-5.84/2-8), К-202 А/В (2D12-68.8/3-6) and К-203 А/В (2D5.5-17.5/8).
Equipment in this series is almost always installed in pairs, so a standby unit allows one machine to be taken out for repair without shutting the process down. We plan the work around exactly that: one unit is overhauled and brought back on load first, and only then is the second stopped.

- Ariel Corporation — reciprocating gas compressors
- Howden Turbo — screw compressors
- FS-Elliott Machinery — Polaris centrifugal compressors
- Shenyang Blower Works Group — centrifugal and reciprocating machines
