EP-CM200GPV | 200 kW Asymmetric VSD Water-Lubricated Compressor — 7.1–17.8 m³/min at 40 Bar

As PET bottle blowing facilities scale toward higher production volumes, the compressed air demand they place on their infrastructure grows in complexity as well as magnitude. Large continuous production sites — those running 24-cavity rotary lines at full speed, multi-line operations producing different bottle formats around the clock, or contract blow molding facilities handling diverse client specifications simultaneously — require a compressor that matches the scale of their operation while retaining the flexibility to track demand across every phase of their production schedule.

The EP-CM200GPV is built for exactly this scale. At 200 kW total motor power and a variable output range of 7.1–17.8 m³/min (251–629 cfm) at pressures up to 4.0 MPa (40 bar), it delivers the highest peak output of any single-enclosure CMG series configuration below the EP-CM242GPV and EP-CM320GPV — while maintaining the full water lubrication technology package: ISO 8573-1 Class 0 oil-free air, isothermal compression at ambient +15°C, single-stage 40 bar capability, and a design service life exceeding 25 years.

The asymmetric 90+110 kW motor architecture creates three genuinely distinct power stages that align naturally with the demand structure of large multi-format production environments. The 90 kW motor handles lower demand periods; the 110 kW motor covers medium demand independently; both motors combined deliver the full 17.8 m³/min output at peak production speed. This three-stage structure means the EP-CM200GPV wastes less electricity during partial-load periods than symmetric dual-motor designs, which jump between two output levels rather than three.

Water Lubrication at 200 kW: Thermal Management at Scale

At 200 kW input power, the heat generated during compression is substantial. In a dry oil-free compressor at this scale, managing this heat requires extensive multi-stage intercooling infrastructure — adding equipment cost, maintenance complexity, and thermodynamic losses at every stage boundary. The EP-CM200GPV addresses this challenge structurally rather than mechanically: water injected throughout the compression cycle absorbs heat continuously at the point of generation, maintaining the compression chamber at only ambient +15°C regardless of motor load or production speed.

This isothermal compression approach delivers three compounding benefits at the 200 kW scale. Energy consumption is reduced by more than 10% versus adiabatic dry compression at equivalent output — a saving that, at 200 kW and 8,000 annual operating hours, represents a meaningful annual electricity cost reduction. Discharge air temperature remains below 55°C under all operating conditions, reducing the moisture load on downstream dryers and extending desiccant service intervals. And the absence of intercooling infrastructure simplifies the compressed air system layout — fewer components between the compressor and the blow mold inlet means fewer potential failure points and simpler facility integration.

Key Engineering Features

Stainless Steel Air End — 25-Year Design Life

The fully stainless steel air end, independently developed with Ever Power's patented no-shaft-sealing design, is rated for over 25 years of continuous 7×24 operation. At 200 kW and 40 bar, the single-screw geometry's balanced force condition — radial loads cancelling across symmetrically placed star wheels — prevents the bearing fatigue that limits high-pressure twin-screw service life.

Schneider Electric PLC — Industrial-Grade Control

The French Schneider Electric logic control system provides millisecond-level pressure monitoring, fault detection with early warning outputs, and automated motor staging decisions across both the 90 kW and 110 kW drives. The 10-inch touch screen displays all real-time operating parameters for both motors, while the 485 communication interface enables direct SCADA integration.

IoT Wireless Monitoring — Remote Visibility

The integrated IoT monitoring module enables remote start/stop, real-time parameter streaming for both motor systems, alarm notification to mobile devices, and data logging for production reporting and predictive maintenance analysis. For large facilities with multiple compressors, the IoT system supports centralized monitoring of the entire compressed air plant from a single interface.

0.1 μm Lubricating Water Filtration

The stainless steel water filtration system uses high-precision glass fiber cotton multi-layer elements achieving 0.1 μm filtration accuracy. Filtered water maintains the cleanliness of the lubrication medium throughout the operating cycle, protecting the air end from particulate damage and extending service intervals in facilities where ambient dust or water quality may vary.

Customer Case Studies

Turkey — High-Speed Carbonated Beverage Producer

Industry: CSD Beverages  |  Application: 40 bar oil-free air for dual 12-cavity CSD rotary lines running simultaneously

"We run two 12-cavity CSD blowing lines simultaneously at 40 bar. The EP-CM200GPV's 17.8 m³/min peak output comfortably handles both lines at full production speed with margin. The three motor-stage structure means that when one line is in a format changeover, the compressor automatically drops to the 110 kW stage, saving electricity without any manual intervention. Our operations director confirmed 31% energy reduction versus our previous compressor installation in the first operating year."

Australia — Large Water & Juice Bottling Facility

Industry: Beverages  |  Application: 35–40 bar VSD air for 24-cavity rotary line producing mineral water and juice bottles on alternating runs

"Our 24-cavity rotary machine is the highest-demand equipment in our facility. The EP-CM200GPV is the only single-unit water-lubricated compressor with sufficient output to supply it at full speed. The asymmetric motor configuration has proven particularly useful — when we switch from mineral water (35 bar) to juice (38 bar) production, the control system adjusts automatically and maintains the new pressure setpoint within seconds. Water lubrication TUV certification satisfies both our food-grade and pharmaceutical-grade bottle client requirements."

South Korea — Integrated PET Packaging Group

Industry: Packaging  |  Application: 28–40 bar variable-pressure air for five different PET bottle formats across three production lines

"We produce five bottle formats across three lines with pressure requirements from 28 to 40 bar. Previously we ran three separate compressors — one per line — with separate maintenance schedules. Consolidating to a single EP-CM200GPV simplified our entire compressed air infrastructure, reduced maintenance personnel requirements, and gave us the IoT monitoring capability to track compressed air system performance from our central operations dashboard. Total annual maintenance cost dropped by more than half."

Frequently Asked Questions

What scale of PET blowing operation is the EP-CM200GPV designed for?
The EP-CM200GPV is designed for large-scale facilities operating high-speed rotary lines with 20+ cavities, multi-line installations producing 50,000+ bottles per hour combined, or contract blow molding operations running multiple formats simultaneously. At 17.8 m³/min peak output, it supports a single 24-cavity rotary line at full speed or two mid-size lines operating simultaneously at 40 bar.
How does the 90+110 kW asymmetric pairing benefit large blowing operations?
The asymmetric pairing creates three operating stages: 90 kW alone for lower demand (~7.1–10 m³/min), 110 kW alone for medium demand (~10–14 m³/min), and both combined for peak demand up to 17.8 m³/min. This three-stage profile aligns naturally with the demand structure of large multi-format facilities — line speed transitions, format changeovers, and maintenance windows each fall within a different stage, minimising electricity waste across every production phase.
Can the EP-CM200GPV supply multiple blowing lines simultaneously?
Yes. At 17.8 m³/min peak output, two mid-size rotary lines each consuming 7–8 m³/min at 35 bar can be supplied simultaneously. For facilities with lines at varying pressures, a shared high-pressure header with individual line pressure regulators is the standard configuration. Ever Power's engineering team can design the complete multi-line compressed air distribution system around the EP-CM200GPV.
What is the FAD turndown ratio and why does it matter?
The EP-CM200GPV operates stably from 7.1 to 17.8 m³/min — a 2.5:1 turndown ratio (minimum 40% of maximum). For large facilities where demand varies significantly between production peaks and maintenance windows, this range allows continuous demand tracking without operating outside the stable range — preventing the pressure instability that causes blow-mold defects during low-demand periods.
How does water lubrication benefit large compressors specifically?
At 200 kW, water injection absorbs the substantial compression heat continuously at the point of generation, maintaining isothermal conditions and avoiding multi-stage intercooler complexity entirely. This delivers 10%+ energy savings versus adiabatic dry compression at equivalent output, keeps discharge temperature below 55°C, and guarantees ISO 8573-1 Class 0 oil-free air throughout the full operating envelope — benefits that scale proportionally with power class.
