Voith LP 560 Air Compressor Saves Energy in Truck Sector

Voith air compressors are technological leaders and, especially in the truck sector, also represent a significant milestone on the road to more environmentally friendly mobility. Due to their two-stage compression with intermediate cooling, they greatly outperform single-stage air compressors in delivery mode. And this is with much lower energy consumption and CO2 emissions. What’s more, even in non-delivery mode, Voith air compressors provide for maximum efficiency and lower emissions with innovative technologies. This is best shown by the LP 560, which has already proven its success in use in the high-efficiency lines of major truck manufacturers – with two cylinders, an extra lightweight housing, TwinSave technology, and a maintenance-free dual-taper coupling. 

“The economical and particularly environmentally friendly design of the LP 560 is actually well thought out down to the smallest detail,” says Jörg Auerswald, vice president engine components at Voith Turbo. “It all starts with the extra lightweight high-pressure die-cast aluminum housing that allows for a higher payload due to its lower weight – while offering better corrosion protection and optimal heat transfer.” 

The real heart of the LP 560 is the integrated TwinSave technology. In practice, this means that each of the two compressor stages has a control valve. If the valves are opened in non-delivery mode, neither of the compressor stages performs compression work. Instead, the air can circulate freely in the unit. This reduces the drive power and additionally provides significant savings in terms of energy consumption and CO2 emissions. In non-delivery mode, it offers total savings of up to 15 percent over single-stage air compressors and technologies based on the self-idling system (SLS). 

The LP 560’s innovative dual-taper coupling also saves energy and emissions as well as weight and installation space. The low energy consumption in non-delivery mode, the optimized weight compared with that of coupling solutions commonly used today, and the flange-integrated design make this possible. In addition, the dual-taper coupling is completely maintenance-free and fail-safe, as no replacement of wear parts is required. This additionally reduces the CO2 emissions by approx. 30 percent. 

“In short, the perfect interplay between all components supports the economical and particularly environmentally friendly design of the LP 560 – both in theory and in practice – and thus naturally makes it interesting for the numerous major truck manufacturers that are already favoring it for installation into their high-efficiency lines today,” says Auerswald.
