JY M-family oxygen reciprocating compressor selections — Jiangxi Gas Compressor — JY Ganzhou

Datasheet

Product overview

Power: Selected M rows: 900 / 1200 kW · Pressure: Selected outlet 0.80 / 3.00 MPa; inlet duty to confirm · Flow: 135 / 80 / 100 m³/min, separate selected duties

Jiangxi's oxygen/nitrogen catalog distinguishes air-separation, PSA and high-pressure filling duties. The manufacturer describes gas-contact stainless-steel housings and stainless-steel cooler cores, different cylinder arrangements and predominantly oil-free gas-side designs. The original combined image contains separate air, oxygen, nitrogen and filling sections. The M-family selections here come specifically from the non-lubricated oxygen-compressor section, not an air or nitrogen row.

4MW-135/1.7–8 gives 135 m³/min with 0.17 MPa inlet explicitly annotated, 0.80 MPa outlet, four rows/three stages, 1,200 kW, 6,800 × 4,000 × 3,200 mm and 26.00 t main-machine mass. Its supply cell lists 6 kV / 10 kV alternatives. 4MW-80/30 instead gives 80 m³/min and 3.00 MPa outlet, four rows/four stages, 900 kW, the same listed dimensions and 26.00 t. The latter row does not independently state inlet pressure. 4MW-100/30 gives 100 m³/min and 3.00 MPa outlet, four rows/three stages, 1,200 kW, the same listed dimensions and 26.50 t.

The table labels flow m³/min and pressure MPa without specifying absolute/gauge or volume reference conditions. Do not silently change these to Nm³/min or decode missing inlet conditions from a model name. Request the offered duty and current drawings. The 2021 news photograph is identified as an M-type oxygen main machine for the Middle East, but its exact table model is not named. Specify oxygen composition, source-pressure range, gas-contact materials, cleanliness/preservation and qualified installation responsibilities. Agree leakage/performance acceptance, cooling and electrical requirements, controls and interlocks, foundation loads, maintenance clearance and destination approval scope.
