As the commercial vehicle industry moves toward electrification, new challenges emerge. Compressed air is vital for systems like brakes and suspension in trucks, buses, and coaches. Traditional air compressors, built for combustion engines, are often noisy and need frequent maintenance. ZF, a global leader in automotive technology, introduces the e-comp Scroll, an advanced air compressor designed specifically for electrified commercial vehicles.
Key Highlights
- Oil-free design: Eliminates oil leaks and disposal, cutting maintenance costs and environmental impact.
- Low noise and vibration: Operates at around 67 dB, similar to office noise, improving comfort.
- Efficient operation: Features variable speed and automatic shut-off to save energy.
- Supports zero-emission goals: Fits ZF’s portfolio for sustainable, electrified vehicles.
- Global launch: Showcased at expos in the US and China.
The e-comp Scroll uses a scroll mechanism to compress air, unlike the noisier piston compressors found in traditional vehicles. This is key for electric trucks and buses, where quiet operation enhances the experience for drivers and passengers. At 67 decibels—about the level of a normal conversation—it blends seamlessly into the background.
Its oil-free system removes the hassle of oil changes and prevents leaks, lowering costs and supporting eco-friendly goals. The compressor also adjusts its speed to match demand and shuts off between cycles, boosting energy efficiency and extending vehicle range.
With a pressure capacity of 12.5 bar (181 psi) and a discharge temperature below 90°C (194°F), thanks to an inverter and liquid cooling, it’s built for performance. ZF’s Pawel Porczyński notes, “The innovative design ensures efficient air compression while significantly reducing Total Cost of Ownership.”
ZF is showcasing the e-comp Scroll at the Advanced Clean Transportation Expo in California and Auto Shanghai, reinforcing its role in advancing zero-emission commercial mobility.
