Oxygen and Nitrogen Booster
93 m³/min · 3.5 MPa (35 bar) · 4-column MW
Four-column MW-type reciprocating compressor for oxygen and nitrogen service in large-scale cryogenic air separation plants. Higher outlet pressure than the standard 30 bar specification — 3.5 MPa (35 bar). Supplied against process data sheet. API 618 compliant.
Confirmed Technical Parameters
The following parameters are confirmed from factory product documentation. Motor power, weight, overall dimensions and compression stages are determined by process conditions and provided on enquiry — we do not publish estimated values.
What the 4MW-93/35 Is
4MW identifies a four-column MW-type reciprocating compressor frame — a heavier-duty platform than the ZW series, engineered for the sustained mechanical demands of large-scale continuous gas service. 93 is the rated flow in m³/min. 35 is the outlet pressure in bar (3.5 MPa).
The 3.5 MPa outlet pressure distinguishes this machine from the standard 3.0 MPa industrial oxygen pipeline specification. In air separation plant applications, this higher pressure is specified where the downstream distribution pipeline requires additional margin, or where process conditions demand more than 3.0 MPa.
The product image shown is an engineering 3D rendering accurately representing the machine's four-column layout, skid base, inter-stage cooling arrangement and instrument piping. A factory-assembled unit photograph is available on request.
The standard industrial oxygen pipeline pressure is 3.0 MPa (30 bar). The 4MW-93/35 operates at 3.5 MPa (35 bar) — applicable where the ASU process design or downstream pipeline conditions require the higher level. Confirm your required outlet pressure from the ASU process data sheet before specifying this model.
The MW-Type Frame
The MW platform is a distinct reciprocating compressor design from the ZW series, developed for higher capacity and the mechanical demands of large-scale continuous industrial gas service.
Piston forces on opposing columns act in opposite directions, partially cancelling each other. This reduces the net unbalanced force transmitted to the foundation compared to a two-column machine of equivalent capacity.
Crankshaft, bearings, crossheads and connecting rods are specified for long-interval overhaul schedules consistent with ASU plant maintenance cycles.
Designed to API 618 (Reciprocating Compressors for Petroleum, Chemical and Gas Industry Services) — the international standard required by EPC contractors for major industrial gas projects.
We supply a complete documentation package: general arrangement drawing, foundation loading diagram, P&ID, IOM manual, factory performance test certificate and material certificates. Witnessed FAT and SIL documentation available on request.
4MW-93/35 vs 4ZW-84/30
Both are confirmed from factory documentation. Two distinct machines on different frame platforms — frame selection is determined by the ASU process data sheet.
MW and ZW are different frame platforms and are not interchangeable. If your data sheet specifies parameters only, contact us for frame guidance.
