SKU: EP-CM200PV

The EP-CM200PV is a 200 kW permanent magnet VSD water-lubricated oil-free screw compressor delivering 14.65–36.63 m³/min at 0.8–1.25 MPa — a very large VSD model for steel rolling mills where production speed varies continuously, airport central compressed air systems with variable terminal gate demand, and major industrial utilities requiring energy-optimised Class 0 oil-free air at the 36+ m³/min scale.

Description

EP-CM200PV | 200 kW VSD Water-Lubricated Oil-Free Compressor — 36.63 m³/min Tracking Steel Mill Production Speed

Steel rolling mills and large airport infrastructure share a compressed air demand characteristic that creates a compelling case for VSD at 200 kW scale: their demand varies continuously with an operational variable — rolling speed in the steel mill, flight schedule in the airport — that is inherently variable and cannot be managed to a constant level. In a steel rolling mill, every product grade change is a demand change. In an airport, every flight bank cycle is a demand cycle. Fixed-frequency compressors serve these variable demands at constant electricity cost; the EP-CM200PV does not.

At 200 kW (270 HP) with a variable output range of 14.65–36.63 m³/min (517–1,293 cfm) at 0.8 MPa, the EP-CM200PV's permanent magnet VSD tracks steel mill production speed variations and airport terminal demand cycles with the same precision that those facilities' process control systems track their respective operational parameters. Structural ISO 8573-1 Class 0 oil-free air is maintained across the full VSD range — protecting steel mill surface quality at all rolling speeds and meeting airport facility quality requirements at every flight schedule demand level. ±0.1 MPa pressure stability ensures consistent pneumatic control performance regardless of current demand. For major facility compressed air infrastructure design, our engineering team provides complete VSD station analysis.

Key Features

Continuous Rolling Speed Demand Tracking

The EP-CM200PV tracks steel mill compressed air demand variation caused by rolling speed changes in real time — accelerating to match high-speed thin strip production and reducing for heavy plate low-speed rolling. Energy consumption follows the rolling programme rather than running at thin-strip capacity cost throughout all product grades.

400,000–500,000 kWh Annual Saving Potential

At 200 kW and 65% average demand: annual VSD saving versus fixed-frequency amounts to approximately 400,000–500,000 kWh — one of the highest absolute annual savings in the CMPV series. At industrial electricity rates, VSD premium payback is typically within 6–9 months.

Airport Flight Schedule Demand Tracking

Airport terminal compressed air demand follows the flight schedule — peak during morning and evening bank departures, lower during off-peak periods. The EP-CM200PV's VSD reduces speed and electricity consumption during off-peak flight periods automatically, without schedule programming or manual adjustment.

Same Footprint as EP-CM160PVF — 27% More Output

The EP-CM200PV shares the same 3100×1700×2090 mm dimensions and approximately the same weight as the EP-CM160PVF while delivering 27% more maximum output (36.63 vs 28.85 m³/min). For facilities where equipment room space constrains compressor selection, this output density is a significant practical advantage.

Structural Class 0 at Rolling Mill Scale

Water lubrication's structural Class 0 guarantee is maintained at all rolling speeds and all VSD settings — from minimum 14.65 m³/min at reduced rolling speed to maximum 36.63 m³/min at full thin-strip production. Steel surface quality protection from oil contamination in process air is consistent across the entire rolling programme.

200 kW Zero Inrush — Mill Electrical Protection

VSD soft-start at 200 kW eliminates inrush currents of 1,200–1,600 A that fixed-frequency startup generates. For steel mill electrical infrastructure where large motor startups are already a significant grid management challenge, the EP-CM200PV's zero-inrush startup reduces electrical demand peaks and protects switchgear rated near its capacity limit.

Customer Case Studies

Japan — Integrated Steel Rolling Mill

Industry: Steel Manufacturing | Application: VSD process and instrument air for a hot strip and cold rolling mill with continuous product grade changes

"Our rolling mill changes product grade — and therefore rolling speed and air demand — multiple times per shift. Previous fixed-frequency compressors ran at constant cost regardless of the current grade. The EP-CM200PV tracks each grade's air demand in real time. Annual energy saving: 23% versus the fixed-frequency unit it replaced. The structural Class 0 oil-free air supply has also eliminated oil-related surface quality issues on our automotive-grade cold-rolled products."

★★★★★

UAE — Major International Hub Airport

Industry: Airport Infrastructure | Application: VSD central compressed air for boarding bridges, gate systems, and maintenance workshops across a major hub airport with variable daily flight schedules

"Hub airports have extreme demand variation between peak morning/evening departure banks and overnight minimum operations. The EP-CM200PV tracks our daily flight schedule automatically. Overnight compressed air electricity is 41% lower than peak-morning electricity — exactly matching our flight schedule demand ratio. Zero unplanned failures in 26 months. The VSD soft-start has also eliminated the voltage sag events that previously caused boarding bridge control system resets during compressor startup."

★★★★★

Brazil — Large Automotive Stamping and Body Welding Plant

Industry: Automotive Manufacturing | Application: VSD central compressed air for press shop, body welding, and electrocoat surface treatment with variable daily production scheduling

"Our production schedule changes week to week based on model demand — some weeks we run three shifts on all lines, some weeks two shifts on selected lines. The EP-CM200PV adjusts to each week's schedule without any manual intervention. Annual energy saving versus our previous fixed-frequency central station: 26%. The structural Class 0 water-lubricated design has eliminated oil-related electrocoat surface defects that were recurring with our previous oil-injected installation."

Frequently Asked Questions

How does the EP-CM200PV benefit a steel rolling mill where production speed varies continuously?

Steel rolling mill production speed — and therefore compressed air demand for descaling, hydraulic control, and cooling water systems — varies continuously with the product being rolled. Thin strip at high speed requires different compressed air profiles than heavy plate at low speed. The EP-CM200PV's VSD tracks this continuous production speed variation, adjusting output from 14.65 to 36.63 m³/min in real time to match the current rolling programme's air demand. Energy consumption follows the actual production programme rather than the peak-speed capacity throughout all product grades.

What is the annual energy saving potential of the EP-CM200PV at this power class?

At 200 kW, 8,000 annual operating hours, and 65% average demand: VSD energy saving versus fixed-frequency operation amounts to approximately 400,000–500,000 kWh per year — among the highest absolute annual savings in the entire CMPV series. At industrial electricity rates, this saving is substantial in absolute terms and recovers the VSD premium within the first 6–9 months of operation for most large facilities with variable demand profiles.

How does the EP-CM200PV serve an airport central compressed air system with variable terminal demand?

Airport terminal compressed air demand varies with flight schedules — peak during morning and evening departure banks, lower during overnight and mid-afternoon off-peak periods. Gate bridge pneumatics, terminal HVAC damper actuators, maintenance workshop tools, and apron equipment draw air at rates that follow the flight schedule rather than a constant level. The EP-CM200PV's VSD tracks this schedule-driven demand variation, reducing electricity consumption during off-peak flight periods.

Does the EP-CM200PV support integration into a steel mill energy management system?

Yes. The 485 communication interface provides real-time VSD data — speed, power, flow, pressure — for integration with steel mill process control systems and energy management platforms. For steel mills operating under ISO 50001 energy management or corporate decarbonisation targets, the EP-CM200PV's compressed air energy data contributes to facility-level monitoring and reporting alongside other major energy consumers.

What is the weight and footprint of the EP-CM200PV and what installation requirements does it have?

The EP-CM200PV weighs 3750 kg with dimensions of 3100×1700×2090 mm — compact relative to its 200 kW power class, sharing the same footprint as the EP-CM160PVF. Standard reinforced floor with anti-vibration mounts is adequate for most industrial building types. The VSD inverter is integrated within the enclosure; no external drive cabinet is required. Electrical connection for 200 kW three-phase supply and compressed air outlet piping are the primary installation requirements.
