More power, less energy consumption – Voith air compressors with SLS, TwinSave technology or integrated clutch
With leading technology, Voith air compressors use two-stage compression with an intercooling system. In comparison to single-stage air compressors, this allows for substantially higher output with a significantly reduced energy consumption in delivery mode. Even more, Voith air compressors with innovative technologies also provide maximum efficiency in non-delivery mode.
Voith air compressors make an important contribution to the cost-effectiveness and sustainability of internal combustion engines. The two-stage compression with an intercooling system plays a decisive role here. This significantly lowers the power consumption in delivery mode. In addition, the reduced compression temperature allows for considerably longer operating times, which increases the maximum delivery capacity with the same cylinder displacement. The lower temperatures also ensure that the oil does not "crack." Fewer damaging byproducts protect the compressor, engine, compressed air system and the environment at the same time. Furthermore, smart technologies such as SLS, TwinSave or an integrated clutch effectively lower energy consumption in non-delivery mode. Another contribution to more sustainability is the low weight of the systems thanks to the light-weight aluminum construction in large-volume production. Voith air compressors thus guarantee maximum energy efficiency, low-emission operation, low weight and long maintenance intervals.
Product highlight
A true innovation: Voith air compressors with TwinSave technology have a control valve in both compressor stages. If the valves are open during non-delivery mode, neither of the compressor stages provides compression. The air can circulate freely in the unit. This reduces the input power and allows additional savings in terms of the energy consumed in non-delivery mode compared to air compressors using SLS technology.

Operating principle
Division of labor – the principle behind two-stage compression
Idling systems – saving energy in non-delivery mode with SLS, TwinSave or integrated clutch
The SLS idling system – intelligently reduced energy consumption
With the Voith SLS idling system, a drain valve in the first compressor stage is opened during non-delivery mode. As a result, virtually no pressure is built up despite the motion of the pistons. This reduces the input power required by the compressor, lowers energy demand and decreases fuel consumption significantly at the same time.
TwinSave technology – two valves for double savings
Voith goes one step further with TwinSave technology. Voith air compressors using TwinSave technology have an additional control valve in the second compressor stage and are actuated externally. This also allows operation with the pressure line closed. For a TwinSave air compressor in non-delivery mode, both control valves are open so that neither of the two compressor stages is compressing. The air can circulate freely within the unit. This further reduces the input power needed in comparison to the SLS. In addition, pressurized components are under far less stress in non-delivery mode, which extends their overall service life.
Clutch compressors – noticeable savings due to mechanical separation from the drive train
With Voith air compressors, a mechanical clutch can be optionally integrated. With this option, the clutch with the drive gear fits perfectly in the existing installation space. If no compressed air is required, the air compressor is disconnected from the drive train via the integrated coupling and stands still. This reduces energy consumption and increases service life.
