Four compression routes, four different engineering briefs
Shanghai Xinran Compressor Co., Ltd. supplies compressed-air equipment and specialist gas-compression systems. Its company presentation dates the business to 2008 and places it within Asia Pacific Universal Machinery, with equipment design, custom manufacturing and testing among its described activities.
Start with the medium and pressure
Two-stage oil-injected screw packages serve a different selection from low-pressure oil-free process air. Magnetic-bearing centrifugal equipment needs a station performance map; hydrogen diaphragm systems need a gas-process duty and engineered skid boundary.
The company also publishes a site entrance bearing the Shanghai Xinran and Jiangsu X.E.S. names. Put the exact contracting entity, production location and test location on the purchase documents.
- Plant air: pressure-specific XR-SY points
- Process air: low-pressure duty and cooling version
- Centrifugal: load envelope and station control
- Hydrogen: inlet state, stages and gas-contact design
01 · Two-stage oil-injected screw
Keep XR-15SY capacity paired with its pressure
XR-15SY: 15 kW · 1500 × 1000 × 1300 mm L × W × H · 1000 kg.
| Pressure | Flow |
|---|---|
| 0.7 MPa | 2.9 m³/min |
| 0.8 MPa | 2.8 m³/min |
| 1.0 MPa | 2.4 m³/min |
| 1.3 MPa | 2.2 m³/min |
Select pressure at the user after pipework and treatment losses. Request the flow reference conditions, test method and complete-package input power for the offered point.
XR-SY selection details →For variable demand
Provide minimum, normal and peak consumption, shift hours and existing compressor controls. Agree the operating range and station sequencing before comparing energy use.
For the installation
Confirm electrical supply, cooling, service access, inlet filtration, condensate handling and the dryer/filter/receiver boundary. A motor rating does not define the entire station.
02 · Single-stage low-pressure oil-free screw
Choose the pressure the process actually needs
A wider pressure range in a family heading does not move this row's capacity to another pressure. Obtain a selection sheet with the exact cooling version and flow reference conditions.
Low-pressure equipment details →03 · Magnetic-bearing centrifugal air
Evaluate the station across its load envelope
Published arrangement
High-speed motor and magnetic bearings, with auxiliary bearings and a manufacturer-described backup arrangement for power loss. Monitoring includes bearing temperature, shaft trajectory and motor windings, alongside central control.
The selection document to request
A model-specific performance map at required pressure, minimum and normal flow, inlet/ambient conditions and available cooling utilities. Include complete-package input power and how the unit operates beside existing machines.
Centrifugal enquiry details →Low flow and station control
Agree low-flow protection, sequencing, start/stop logic, communications and the treatment boundary. Compare offers across the intended load range.
Loss of power and restart
Review the auxiliary-bearing and backup arrangement, shutdown response, restart procedure and post-event inspection. Put these responsibilities on the commissioning and maintenance scope.
04 · Hydrogen diaphragm compression
Define the gas duty before choosing a frame
The diaphragm arrangement separates compressed gas from the lubricating system. Xinran's family table lists 1–3 stages and a discharge-pressure ceiling of 100 MPa(G).
These are frame data, not a hydrogen flow guarantee at the family pressure ceiling. Maximum motor power is also different from absorbed package input.
Hydrogen skid enquiry details →Send the inlet state and downstream requirement
- Gas: composition, purity, inlet temperature and pressure; distinguish absolute and gauge pressure.
- Duty: outlet pressure, normal/peak flow with reference conditions, operating cycle and storage or process arrangement.
- Engineering boundary: stages, gas-contact materials, interstage cooling, leak monitoring, relief/shutdown, purging and hazardous-area requirements.
- Acceptance: selected frame/motor, process documents, performance/leakage criteria, commissioning and maintenance responsibilities.
A quotation that can be compared
Align duty, utilities and delivery scope
Technical selection
Exact model or engineered configuration, pressure and flow basis, input power, electrical supply, cooling utilities and general arrangement. Attach the demand profile or hydrogen process brief.
Purchase and acceptance
Contracting entity, production/test locations, inspection procedure, model-specific documents, treatment and controls, installation/commissioning boundary and routine spare parts.
Separate options from the base package. Keep the quote, selected performance sheet and approved drawings tied to the same duty.
Send a Xinran equipment and duty brief →Xinran selection questions
Does XR-15SY deliver 2.9 m³/min at 1.3 MPa?
The table pairs 2.9 m³/min with 0.7 MPa. At 1.3 MPa its listed flow is 2.2 m³/min. Keep the pressure and capacity together and confirm the flow test basis.
Does oil-free mean the installed process air meets my quality standard?
Define the required quality at the point of use, treatment and acceptance evidence for the selected package and installation.
Can I select hydrogen capacity from the 100 MPa ceiling?
The ceiling is a family limit. Actual selection needs gas composition, inlet state, outlet pressure, flow basis and duty cycle, followed by a frame, stages and skid configuration.
Why are the family pictures labelled differently from the table references?
The two-stage image shows XR-250 and the low-pressure image XR-22. Their captions identify the illustration scope; the selected model's dimensions and configuration must come from its own drawing.
