SKl-E Pack from CVS engineering – the alternative
to conventional unloading systems

ith the SKL-E Pack system, CVS engineering GmbH
Wfrom Rheinfelden has introduced an energy-efficient
solution for the rapid stationary unloading of silo vehicles. The
emission-free unit from the manufacturer of compressors and
vacuum pumps for vehicles ensures a smooth unloading pro-
cess for bulk goods. Typical customers are companies from
the food production, construction, chemical and logistics in-
dustries as well as recycling and environmental technology.
One advantage of the system is that no engine or compressor

ing of grain, sugar, flour, cement, lime, PVC granulates, soda or
animal feed, ensuring a low-emission and low-noise process.
The stationary system can also be operated independently of Patrick Zettler.
