PRODUCT OVERVIEW
Mechanical Drive.
The industrial-drive section covers air separation, ethylene, ammonia, metallurgy, PTA and coal-chemical applications. The described driven equipment includes compressors, fans and pumps.
The four H/L entries distinguish back-pressure, condensing and extraction arrangements. CHENDA organizes the steam conditions, load and shaft-interface information for manufacturer clarification.
CATALOGUE REFERENCE
Series parameters.
Compare each row as a separate catalogue reference. Final selection depends on the complete operating duty.

| Series | Arrangement | PowerMW | Inlet conditions | Exhaust pressureMPa | Extraction | Speedrpm | SourcePDF page | Enquiry |
|---|---|---|---|---|---|---|---|---|
| H/LB | Back pressure | ≤100 | ≤13.2MPa, 566℃ | >0.1 | Not stated in this column | ≤13000，Variable | p. 25 ↗ | |
| H/LCB | Extraction back pressure | ≤100 | ≤13.2MPa, 566℃ | >0.1 | According to demand | ≤13000，Variable | p. 25 ↗ | |
| H/LN | Condensing | ≤100 | ≤13.2MPa, 566℃ | <0.1 | Not stated in this column | ≤13000，Variable | p. 25 ↗ | |
| H/LCN | Extraction condensing | ≤100 | ≤13.2MPa, 566℃ | <0.1 | According to demand | ≤13000，Variable | p. 25 ↗ |
The inlet temperature is retained as printed, without adding an independent upper-limit symbol. The pressure reference and minimum operating speed are not stated.
The power and speed upper limits do not establish one guaranteed operating point or define the complete shaft-load envelope.
Case-specific driven-equipment ratings are not added together and presented as a turbine’s rated shaft output.
Full source reading notes
The inlet notation is reproduced as ≤13.2MPa, 566℃. The source does not place ≤ before the temperature.
The pressure reference (absolute or gauge) and minimum speed are not stated in this series table.
Values belong to their stated series. Do not combine maximum values into a single operating duty.
Series scope.
- The back-pressure and condensing entries retain their separate exhaust-pressure conditions.
- H/LCB and H/LCN explicitly describe extraction according to demand, without a numerical extraction-flow schedule.
- The same page gives distinct air-separation, ammonia-compressor and sulfuric-acid-fan examples; their structural details are not assigned to every H/L model.

Questions about this series.
What should accompany a compressor-drive enquiry?
Provide the compressor duty, shaft-power and speed requirements, available steam conditions, and relevant shaft or coupling drawings. CHENDA coordinates open technical questions with the manufacturer.
Is a drive-turbine flow value available in the brochure?
The air-separation example includes an inlet-flow value. That is a single case, not the common inlet-flow limit of all four H/L series or an exhaust or extraction-flow schedule.
