CMN Taizhou: cooling, process pressure and scroll module selection

CMN / XINMAIEN · TAIZHOU BAY NEW AREA

Three oil-free paths, three different installation decisions

辛麦恩科技股份有限公司 is the company named on CMN’s official site, with its operating location in Taizhou Bay New Area, Zhejiang. The company presents single-screw development, manufacture and service. Its technology-history narrative is distinct from the incorporation history of the present Chinese legal entity.

CM/PV · WATER-LUBRICATED PM VARIABLE SPEED

Cooling version changes the space and utilities

The actual CM/PV table labels flow as FAD and distinguishes air-cooled F parameters from water-cooled data. Keep the selected pressure row, version and full flow-reference conditions together.

CM22PV(F) · 22 kW

0.8 MPa

1.40–3.50 m³/min

1.0 MPa

1.25–3.13 m³/min

1.25 MPa

1.04–2.61 m³/min

The CM22PV row lists a 1-inch air outlet. Cooling duty is not measured make-up consumption. Agree water quality, pressure, supply/return and drain arrangement, and the separate lubrication-water circuit. For air cooling, use the F-version drawing and ambient/ventilation limits.

Other selected 0.8 MPa rows are CM08PV(F), 7.5 kW and 0.45–1.15 m³/min; CM75PV(F), 75 kW and 5.16–12.90; CM315PV, 315 kW and 21.80–54.50. These are separate models, not one machine’s complete operating range.

CM/GPV · TWO STAGES, TWO DRIVES

A pressure band needs a curve, not just its largest flow

The manufacturer describes water-lubricated, water-cooled two-stage compression with separate permanent-magnet drives. Its table contains both fixed-speed CM/G and variable-speed CM/GPV entries. The figures below belong to GPV.

CM130GPV appears twice. One entry gives a 2.0–3.0 MPa band with 5.4–13.5 m³/min; the other gives 2.0–4.0 MPa with 4.0–10.2. The pressure band is part of the selected configuration. Neither interval proves maximum flow at every pressure in the band.

For a blowing process, give pressure at the use point, cycle and peak draw, receiver/control concept and minimum sustained demand. Obtain the pressure-matched curve, full volume reference, individual drive data, sequencing and cooling-water requirements. Align pressure-rated piping/receiver documents, drying/filtration and process-air acceptance. If the enquiry says “30 bar”, the 30 bar oil-free duty page explains how to state gauge or absolute pressure and which documented configuration to request.

CMW · DIRECT-DRIVE OIL-FREE SCROLL

Start with the pressure suffix and the service capacity

CMW uses directly driven permanent-magnet scroll airends, with single and multi-airend arrangements. The source describes pressure/warning/maintenance indications and a larger touchscreen on packages with three or more airends; confirm the current supplied controller.

The detailed table gives CMW2.2-0.8: 255 L/min and CMW2.2-1.0: 215 L/min, both at a 2.2 kW motor rating. The suffix matters. Obtain the exact capacity-rating pressure and reference rather than treating the table’s pressure range as constant output.

TECHNICAL PARTICIPATION · ACTUAL DELIVERY SCOPE

Make the air-quality evidence and support terms specific

The national standards platform names 辛麦恩科技股份有限公司 among drafting organizations for plan 20250138-T-604, a revision for general-use oil-injected single-screw air compressors. The observed status is approval in progress. This is a technical-participation record in a different scope, not certification of these oil-free machines.

The company’s service page separates consultation, delivery/start-up and training, after-sales, return visits and maintenance. Its domestic response wording is not a global response-time commitment; put destination coverage, personnel, travel, parts and responsibilities into your quotation.

1. Confirm the actual offered machine

   Model, pressure suffix or band, cooling and drive arrangement, full performance/test reference, actual package input and site conditions.

2. Agree the process-air acceptance

   Current issuer/report and model scope behind any Class 0 claim, particle/moisture requirements, treatment and sampling point. Compressor mechanism alone does not establish a complete food, medical or breathing-air specification.

3. Plan installation and ownership

   Cooling or ventilation, electrical and piping interfaces, access drawings, tests, manuals, wear parts, destination documents, commissioning and ongoing service terms.
