The e-comp Scroll is powered by an integrated electric motor instead of using a combustion engine like in conventional vehicles. It compresses air up to 12.5 bar system pressure in a single stage and is capable of running at variable speeds to meet application demand. The new compressor uses the motion of interlocking scrolls to compress air to minimize vibration while limiting noise emissions to around 67dB(A) at the nominal operation point of 250 litres per minute. ZF claims the noise level is comparable to an office
environment. The technology fulfils diverse requirements, such as system pressure, free air delivery, size and noise levels. Operating oil-free, ZF states the e-comp Scroll eliminates oil leaks as well as oil disposal needs, resulting in low maintenance resulting from elimination of oil lubrication and thus reducing TCO. The system also features an inverter and liquid cooling shell, which maintains the discharge temperature below 90°C (194°F).
