Kaishan Opens New Production Line for Rotary Screw Compressors

Kaishan has commissioned a new production line for rotary screw compressors at its manufacturing facility. The line covers air-cooled and water-cooled screw compressors used in general industry, mining and construction, and is configured to support export orders alongside domestic demand. For buyers, the practical question is not how the line looks, but what it changes in the units that reach the site.

What the New Line Adds

The line is organised around staged assembly in a controlled, clean environment. Frames, airends, motors, coolers and control panels move through defined stations rather than being assembled in one bay. Each station completes a specific task and inspects it before the unit moves on, so a fault is caught at the point where it occurs instead of at final test.

Fastening is torque-controlled and recorded. Critical joints, including airend mounting, pipework and electrical connections, are tightened to specified values with tools that log the result against the unit serial number. This matters because loose or over-tightened joints are a common source of oil leaks, vibration and premature failure in the field.

Testing Every Unit, Not a Sample

At the end of the line, every compressor is run and its delivered volume and pressure are verified against the data plate. This is not a sample check. Each unit is instrumented, run under load, and the measured free air delivery and discharge pressure are compared with the declared figures. Units that fall outside tolerance are corrected and retested before release.

• Staged assembly with in-process inspection at each station
• Torque-controlled fastening with results recorded per serial number
• End-of-line performance verification of flow and pressure on every unit
• Test data retained for traceability

What It Means for Buyers

The main benefit is consistency. When the same torque values, the same inspection points and the same test criteria apply to every unit, the difference between one compressor and the next narrows. For a plant engineer specifying several machines or a contractor adding units over time, that reduces the risk of one machine behaving differently from the rest.

Traceability is the second benefit. Component records and test results are linked to the serial number, which helps when a warranty claim or a performance question arises. Instead of a general discussion, the actual build and test data for that machine can be reviewed.

Lead times on standard models also become shorter and more predictable. A line with defined stations and tested throughput is easier to schedule than a build-to-order bay, so standard configurations can be quoted with firmer delivery windows. Custom or export-specific configurations still depend on component availability and documentation requirements.

Range and Export Support

The line covers rotary screw compressors for general industrial use, mining and construction. Typical working pressures span the common 7 to 13 bar range, with flows matched to the application rather than a single fixed size. Units destined for export are built and tested to the same process, with additional attention to voltage, frequency, documentation and packaging requirements for the destination market.

Seeing the Evidence

Buyers who want to verify build quality before ordering can request a factory visit to walk the line and observe assembly and testing. For those who cannot travel, Kaishan can provide a test report for the specific unit or model under consideration, showing the measured flow and pressure against the data plate. Both requests are handled through the normal sales contact.

If you are specifying a compressor for a particular duty, contact Kaishan engineers with your required pressure, flow, ambient conditions and power supply, and they will recommend a matched configuration.
