EP-CMW18-1.2 Oil-Free Scroll Air Compressor

01. Demand-Matched Energy Efficiency

The PLC controller activates only the number of air-ends required to meet current system pressure demand. During low-consumption periods — shift changes, weekends, reduced production — unused air-ends automatically shut down, reducing power consumption proportionally. This is fundamentally more efficient than throttling a large fixed-speed machine.

02. Automatic Master/Slave Rotation

The controller periodically reassigns which air-end serves as the master (primary load-carrier) and which serve as slaves (secondary support). This rotation strategy distributes cumulative operating hours evenly across all four units, preventing accelerated wear on any single air-end and maximizing the interval between major service events.

03. Operational Redundancy

If one of the four air-ends requires maintenance or triggers a fault, the remaining three continue to supply compressed air at 75% of full rated capacity. For facilities that cannot afford complete compressor shutdowns — continuous process manufacturing, hospital medical gas systems, mission-critical cleanrooms — this redundancy eliminates total system downtime risk.

🔸 Globally Unique 1.2 MPa Scroll Design

Ever Power remains the only manufacturer worldwide to produce an oil-free scroll compressor series commercially rated to 1.2 MPa. Conventional scroll technology plateaus at 0.8–1.0 MPa. The high-rigidity square-frame air-end geometry and precision scroll tip-seal system make sustained 1.2 MPa operation structurally viable and warranty-backed.

🔸 Four Independent PM Motor Drives

Each of the four scroll air-ends is direct-coupled to its own IE4-rated permanent magnet inverter motor. Individual VSD control per air-end means each unit operates at its optimal efficiency point regardless of what the other three are doing. Motor protection is IP65 with Class F insulation, compatible with harsh and humid industrial environments.

🔸 Low Discharge Temperature, Low Dew Point

Each air-end is served by an independent cooling fan that maintains discharge air temperatures close to ambient. This fundamentally low discharge temperature reduces the condensation load on downstream dryers and keeps the pressure dew point at an inherently low baseline — particularly important for sensitive instrumentation and pharmaceutical process gas applications.

🔸 Full Stainless Steel Internal Path

From the 1 μm air intake filtration through the compression chamber, buffer tank, and 1-inch discharge connection, every surface that contacts compressed air is stainless steel. This zero-contamination pathway means the machine can serve as a direct process gas source for the most stringent quality standards — including USP and EU GMP.

🔸 Zero-Discharge Condensate Design

The EP-CMW18-1.2 operates as a zero-discharge system — no oil-contaminated condensate is produced or released. This eliminates the need for oil-water separators and the associated disposal costs and environmental compliance burden that conventional compressors impose on facility operators.

🔸 Compact Footprint for High Output

Delivering 1440 L/min from a machine body measuring 1450 × 900 × 1150 mm (350 kg) represents an exceptionally high output-to-footprint ratio for oil-free technology at 1.2 MPa. Facilities with constrained equipment rooms can achieve large-system compressed air performance without dedicating disproportionate floor space.

🇧🇷 Brazil — Large-Format Beverage Bottling Plant

Industry: Food & Beverage  |  Application: High-speed PET bottle blow-molding air supply at 1.1 MPa

"Our previous setup used two 15 kW oil-flooded screw compressors plus a three-stage filtration train to achieve food-safe air. After installing the EP-CMW18-1.2, we eliminated the entire filtration chain, cut annual maintenance cost by over 60%, and gained the redundancy of four independent air-ends. The PLC's automatic load rotation is something we didn't know we needed — until we saw it working."

🇨🇦 Canada — Semiconductor Research Institute

Industry: Semiconductor Research  |  Application: ISO Class 5 cleanroom compressed air for MOCVD reactors

"We specified the EP-CMW18-1.2 after evaluating five competing platforms. The combination of true 1.2 MPa oil-free output, 61 dB noise level (compatible with our lab environment), and the four-module redundancy met every criterion on our procurement checklist. Twelve months in, total uptime has been 99.97%. The touch-screen fault diagnostics have made the one service event we had completely self-manageable by our in-house technician."

🇳🇱 Netherlands — GMP Pharmaceutical Manufacturer

Industry: Pharmaceutical  |  Application: EU GMP-compliant process air for multi-product sterile filling lines

"Qualifying a compressed air source for EU GMP Annex 1 sterile manufacturing is an intensive process. The EP-CMW18-1.2 was validated faster than any previous compressor system we've qualified, because its oil-free status is structural — there is simply no oil circuit to qualify out of the supply chain. The capacity of 1440 L/min is sufficient for our three parallel filling lines simultaneously, which was the key sizing requirement."
