Clean, efficient, and quiet pneumatic unloading – Without a running truck engine

The SKL-E Pack is the perfect solution for stationary unloading of silo vehicles in locations where noise and emissions must be minimized. Equipped with a high-performance oil-free screw compressor from the SKL 700 or SKL 1100 series, this system provides full unloading power for dry bulk materials – independent of the truck’s engine.

Powered by electricity, the SKL-E Pack enables a low-noise, zero-emission unloading process, making it ideal for urban logistics hubs, industrial facilities, or construction sites in residential areas. The optional integrated frequency converter allows variable speed control, adapting the airflow to current needs and minimizing energy consumption for maximum efficiency.

Combining proven CVS compressor technology with smart control options, the SKL-E Pack is a sustainable, cost-efficient, and user-friendly solution designed for the future of bulk material logistics.
