Lianhe CNG station booster — VF and VFD duty comparison — Bengbu Lianhe Compressor

Datasheet

Product overview

Power: Selected VF/VFD table:75 kW · Pressure: Table inlet3–20 → discharge25 MPa;confirm · Flow: Table1500 Nm³/h;header basis differs

Lianhe presents this selection as reciprocating natural-gas equipment for CNG station service, with project-specific packages. Station type and gas source should be specified separately: trailer/storage pressure changes, pipeline input and station sequencing are not one identical duty.

The detailed table gives VF-0.32/(30-200)-250 at 1500 Nm³/h, 3–20 MPa inlet, 25 MPa discharge and 75 kW, with 5538 × 2350 × 2000 mm and 5.5 t. VFD-0.32/(30-200)-250 gives the same printed capacity, pressures and motor, with 5538 × 2350 × 2438 mm and 9.5 t. The source's air-cooled cell spans the table rows. Request actual foundation, enclosure, auxiliaries and service-access drawings rather than assigning the dimension/mass difference solely from a suffix.

The page header also prints 0.32 m³/min and 0.3–20 MPa inlet; the latter differs from the detailed 3–20 MPa row. Agree the inlet limit and flow bases in the signed performance sheet. The header value is not converted to or treated as equivalent to 1500 Nm³/h. Broader station throughput descriptions are not a guaranteed curve for this machine.

Give the complete inlet-pressure profile, composition and temperature, required delivery pressure, average/peak dispensing demand, available electrical supply and storage/sequence concept. Obtain capacity and package-input curves across the pressure envelope, permissible start/stop duty, cooling demand, gas separation/vent routing and hazardous-area scope. Generic claims about control brands, noise, imported components or service hours do not establish the current offered bill of materials or tested operating conditions.

Confirm control/interlock schedules, relief and shutdown interfaces, installation/service clearances, manuals, spares, commissioning, training and acceptance tests. Product-page one-year warranty wording and ongoing support need start points, exclusions and destination terms in the order. The original paired photographs are non-standard manufacturer package examples; they do not establish the configuration of both VF and VFD numerical rows.
