A named manufacturing company, with the quoted machine's origin made explicit
Ingersoll Rand (China) Industrial Equipment Manufacturing Co., Ltd. is the company identified by this profile. The Chinese legal name is 英格索兰（中国）工业设备制造有限公司.
Jiangsu employer records and Wujiang's 2025 enterprise list locate this company in Wujiang. Ingersoll Rand's China process-compressor page separately identifies an MSG centrifugal manufacturing centre in Suzhou Wujiang.
For a purchase, specify the actual contracting seller, model/suffix and manufacturing origin. An MSG site reference does not automatically establish the production site of an R-Series, Nirvana or Centac package.
Start with the question your air system needs to answer
Which R-Series suffix fits the load?
Fixed-speed i, two-stage fixed-speed ie and variable-speed n have different tables. Compare the chosen pressure and daily demand variation.
Compare R-Series rows →What does the Nirvana package include?
Separate the compressor from the optional dryer, filters and receiver. Identify the old model or currently offered replacement.
Review Nirvana scope →How does Centac run at minimum demand?
Select the site duty, turndown and trim-machine sequence. A catalogue envelope is a starting point, not a performance guarantee.
Build the Centac duty →R-Series · 2025 China brochure · 90–160 kW
The suffix and pressure column change the comparison
The brochure separates i: single-stage fixed speed, ie: two-stage fixed speed, and n: variable speed. Choose the complete model code before comparing capacity.
| Model / pressure column | Nominal power / FAD |
|---|---|
| RS90ie 7–7.5 barg | 90 kW 19.3 m³/min |
| RS90ie 10 barg | 90 kW 16.4 m³/min |
| RS160ie 10 barg | 160 kW 28.9 m³/min |
FAD test basis: ISO 1217:2009 Annex C. Keep the selected pressure column with the model; obtain the offer's actual-site corrections and package input.
Oil-flooded compression requires a treatment decision
Specify the required oil, particle and moisture limits at the point of use, pressure dew point and distribution loss. Itemise dryer, filters, drains and receiver. If heat recovery is wanted, name the heat user and supply/return conditions; a catalogue option alone does not establish useful recovered heat.
Nirvana · Variable-speed screw
Match the existing model and the Total Air System arrangement
The official 15–30 kW product page describes IntelliDrive variable-speed control and optional Total Air System (TAS). The linked 5.5–30 kW brochure is a 2012 edition: use it to identify the documented configuration, then obtain the current offer's performance and availability.
| Model / nominal power | Published capacity range |
|---|---|
| IRN15K 15 kW | 1.16–2.46 m³/min |
| IRN30K 30 kW | 1.16–4.56 m³/min |
Both rows list a 4.5–10.4 barg operating band. Maximum capacity is based on 8 barg and non-TAS machines, tested to ISO 1217:1996 Annex C. It is not the promised maximum at 10.4 barg or through every treatment package.
For a replacement or expansion
- Record machine code/serial details and the existing supply voltage/frequency.
- Confirm the currently offered variant, firmware/control compatibility and destination parts/service support.
- Specify the receiver and destination vessel requirements, dryer/filter scope and treatment pressure loss.
MSG Centac · Centrifugal air
Choose a site duty inside the model envelope
| Model | Flow / pressure ranges |
|---|---|
| C400 | 40–67 m³/min 3.4–8.6 barg |
| C700 | 55–130 m³/min 3.1–10.3 barg |
| 3CII | 185–267 m³/min 3.1–10.3 barg |
The brochure says performance varies with inlet conditions. Flow and pressure are separate selection envelopes, not guaranteed paired points. The webpage has different values; these examples consistently use the dated 2025 brochure.
Request the selected performance map
Provide suction pressure, temperature and humidity, discharge pressure and cooling-water conditions. Ask for minimum stable operation, surge protection and blow-off behaviour alongside normal duty and total package input.
Review the station's overnight/partial-production demand and trim-machine sequence. A maximum-capacity number does not show how the plant runs at minimum load.
Make a technical enquiry that produces comparable offers
Attach the demand profile
State minimum, normal and peak flow, pressure at the point of use, shifts and process interruptions. For R-Series/Nirvana, identify the required drive arrangement. For Centac, include minimum-load and trim-machine operation.
Define the site and package boundary
Supply voltage/frequency, ambient/suction conditions, water utilities where applicable, room limits and maintenance/lifting access. Itemise treatment, receiver, drains, starting and control integration.
Agree the evidence and acceptance
Exact model/suffix and origin, current performance curve, package electrical input, drawings, applicable conformity/air-quality documents, test conditions and witnessing. Match all documents to the actual offered equipment.
Assign delivery and service
Identify the contracting seller, commissioning owner, destination parts/service coverage and current lead time. Confirm Nirvana legacy compatibility separately from a new machine's scope.
Questions that change this selection
Does the Wujiang MSG site reference prove a Centac package's origin?
It identifies the MSG manufacturing-centre reference in the company's China materials. MSG process machines and MSG Centac air machines have separate product routes. Obtain the origin of the exact Centac or screw package in the current technical offer.
Why does RS90ie lose delivery at a higher pressure?
The brochure has separate pressure columns: 19.3 m³/min at 7–7.5 barg and 16.4 m³/min at 10 barg. Compare the same model at the intended pressure rather than combining the lower-pressure flow with the higher-pressure duty.
Can the Nirvana maximum be used at 10.4 barg with TAS?
The displayed legacy maximum is based on 8 barg and non-TAS machines. Request the selected variant's performance through its actual treatment package at the intended pressure.
Can I combine Centac's highest flow and highest pressure?
The brochure gives model envelopes, not a guaranteed operating point for that combination. Submit the inlet and water conditions, then use the selected performance map and minimum-load limits.
