ZF Launches Advanced e-comp Scroll Compressor for Electric Commercial Vehicles

In a bold stride towards the electrification of commercial transportation, ZF Friedrichshafen AG has introduced its latest technological marvel—the e-comp Scroll air compressor. Unveiled at two of the industry's most prestigious platforms—the Advanced Clean Transportation (ACT) Expo in California and Auto Shanghai in China—this state-of-the-art innovation underscores ZF’s unwavering commitment to a zero-emissions future.

Elevating the Standards of Compressed Air Systems

Compressed air remains a cornerstone in commercial vehicle systems, powering critical components such as air disc brakes, suspensions, and various auxiliary mechanisms. Yet, as vehicles transition away from internal combustion engines (ICE) toward electric powertrains, legacy solutions no longer suffice. Traditional piston compressors—once quietly masked by engine noise—now stand out in the hushed operation of electric vehicles.

Enter the e-comp Scroll, a paradigm shift in air compression. This oil-free, low-vibration, and whisper-quiet unit is designed for medium and heavy-duty hybrid, battery-electric, and hydrogen fuel cell vehicles. Utilizing the precise motion of interlocking scrolls, it compresses air efficiently while drastically minimizing acoustic and mechanical disturbances. The result? A mere 67 dB(A) at nominal operation—comparable to the ambient hum of a modern office.

Beyond Silence: Smart, Sustainable, Superior

However, this innovation is more than just quiet. It’s intelligent. Powered by an integrated electric motor, the e-comp Scroll achieves single-stage compression up to 12.5 bar, delivering air at variable speeds tailored to real-time demands. This dynamic responsiveness ensures energy is never wasted—compression occurs only when necessary, conserving power and enhancing operational longevity.

Moreover, the system boasts a liquid cooling shell and integrated inverter, maintaining discharge temperatures below 90°C, even under demanding conditions. Such thermal control not only safeguards performance but extends component life—an essential factor for fleet managers and OEMs striving to reduce maintenance overheads.

“By offering an oil-free, low-noise, and low-vibration air compression system, we are addressing the technological challenges posed by zero-emission targets for electric vehicles,” remarked Paweł Porczyński, Head of Product Line, Chassis Solutions at ZF’s Commercial Vehicle Solutions division. “The e-comp Scroll embodies our mission to lower total cost of ownership while elevating the driving experience.”

Redefining Total Cost of Ownership

The elimination of oil not only enhances environmental stewardship—removing the need for leaks management and waste disposal—but also simplifies system upkeep. The reduction in wear and tear, coupled with minimized service interruptions, represents a dramatic drop in long-term operational expenses.

Furthermore, its compact and modular architecture allows flexible integration into various commercial platforms, from transit buses navigating dense urban grids to long-haul freight trucks traversing intercontinental routes.
