At the historic vehicle manufacturing location of Zschopau in Saxony, Germany, Voith is developing and producing a new generation of air compressors for trucks, buses and special vehicles.
These compressors are characterized above all by substantially higher energy efficiency, low emissions operation, reduced mass and extended maintenance intervals.
Voith benefits not only from the experienced engineers at the location, but also from higher educational institutions and technical institutes in the immediate vicinity.
The pre-charging process of the system with its unique inter-cooling system results in a significantly reduced power uptake during delivery operation. At the same time, the compression temperature drops, which allows longer duty cycles and therefore increases the air delivery per hour, while the stroke volume remains the same.
Outside delivery operation, the newly developed idle system SLS significantly reduces fuel consumption.
As a result of reduced temperatures, the engine oil is subjected to less stress. Oil cracking and the formation of harmful substances are therefore prevented.
The newly developed TwinSave technology is also applicable to various other Voith compressors. TwinSave comes with an additional control valve in the second compressor stage and external actuation. These features allow for operation with a closed pressure line.
In delivery operation, both control valves are closed (normally closed) in order for the compressor to compress and deliver the air in both stages. In idling mode, the control valves are open, which means that neither of the two compressor stages compresses the air and it is circulating inside the unit. Compared to the selfactuating idle system (SLS), Twin Save enables further energy savings of up to 25 percent. In addition, TwinSave technology contributes to the reduction of the mechanical strain on the pressurized components and thus helps to extend their lifetime.
Traveling economically and saving the environment at the same time – auxiliary units such as air compressors in trucks and buses contribute significantly to this. Unique applied at Voith: two stage compression with inter-cooling system. This results in significantly reduced power uptake during delivery operation.
The portfolio covers pre-charged two and three cylinder air compressors made from gray cast iron or cast aluminium. The pre-charging process of the system with its unique inter cooling system results in a significantly reduced power uptake during delivery operation. At the same time, the reduction of the compression temperature allows for longer duty cycles and thus increases the air delivery per hour, while the stroke volume remains the same. Lowering the temperature prevents the oil from cracking and the formation of harmful substances.
