EP-CM150GPV Water-Lubricated Oil-Free VSD Screw Air Compressor for PET Bottle Blowing

Simplified Spare Parts — One Motor Type

Both motors carry identical 75 kW ratings, meaning a single spare motor covers both positions. Facilities do not need to stock two different motor specifications. Maintenance team training is simplified — every technician who knows one motor knows both. This parts-commonality advantage extends to inverter drives, motor bearings, and winding specifications throughout the life of the machine.

Equal Runtime Accumulation

When both motors operate simultaneously at identical loads, they accumulate runtime hours at the same rate. Combined with the automatic rotation logic that alternates primary duty between the two units, both motors reach any given service milestone at the same time — enabling both to be serviced in a single maintenance window rather than requiring separate interventions for each at different intervals.

50% Capacity Fault Fallback

If one motor triggers a fault, the second immediately takes sole operation, maintaining approximately 6.75 m³/min at full working pressure. For most PET blowing configurations, this 50% capacity is sufficient to continue production at reduced speed while the fault is addressed — preventing total production shutdown and the significant batch losses that accompany it.

VSD Pressure Band Control ±0.1 MPa

The Schneider Electric PLC maintains system pressure within ±0.1 MPa of the setpoint across the entire 5.4–13.5 m³/min output range. This tight control prevents the pressure surges that damage mold seals and the pressure drops that cause bottle wall-thickness variations — critical quality parameters on high-speed rotary lines producing hundreds of bottles per minute.

Spain — Mixed-Format Beverage Producer

Industry: Beverages  |  Application: 22–40 bar variable pressure for mineral water, CSD, and juice bottles on shared blowing infrastructure

"Our facility produces three different bottle categories requiring pressures from 22 to 40 bar. Previous installations required separate compressor systems for standard and high-pressure formats. The EP-CM150GPV covers everything in one machine. The symmetric 75+75 kW motors also simplified our spare parts inventory significantly — we stock one motor type instead of two. Energy saving measured at 27% versus our previous fixed-speed installation in the first 12 months."

India — Large Bottled Water Conglomerate

Industry: Bottled Water  |  Application: 35 bar VSD air for high-speed 20-cavity rotary line with seasonal demand fluctuations

"Our production peaks during summer months and drops significantly in winter. A fixed-speed compressor would waste substantial electricity during off-peak months. The EP-CM150GPV stages between single-motor and dual-motor operation based on actual line speed, and our winter electricity consumption from the compressor system dropped 34% versus the previous year. The water lubrication technology has also resolved the air-quality issues we experienced with our old oil-injected system — zero oil-related quality rejections since installation."

Canada — Pharmaceutical Packaging Specialist

Industry: Pharmaceutical Packaging  |  Application: 38–40 bar Class 0 air for PET and PETG pharmaceutical bottle blowing under Health Canada GMP

"GMP validation of a compressed air system requires extensive documentation of oil-free certification. The EP-CM150GPV's structural water lubrication — verified by TUV against ISO 8573-1 Class 0 — provided the clearest validation pathway of any compressor we evaluated. The dual-motor redundancy also satisfies our GMP requirement for compressed air system redundancy in critical pharmaceutical manufacturing environments. We have operated 18 months without a single quality deviation attributable to compressed air."
