Liebherr and Cummins cooperate in power generation

Global Mining Review,

For the new Cummins C25G gas generator series, Liebherr will provide fully equipped gas engines, which comprise ignition and control systems for natural gas and biogas applications in 50 Hz and 60 Hz markets. The C25G is designed to support any power need in different applications – from hospitals and industry to commercial buildings and utilities requiring reliable continuous operation, whether it is grid parallel or island mode.

The G9512, a 12-cylinder gas engine with 25 l displacement, is developed and manufactured at the Liebherr facility in Bulle (Switzerland). The engine is the basis for the new Cummins C25G gas generator series. The latter will cover 500 kW at 50 Hz and 580 kW at 60 Hz for combined heat and power (CHP/CCHP).

Within the scope of supply, Liebherr-Components AG also delivers a control system to secure easy and reliable integration of the engine equipment into the C25G generator series. These systems are developed and assembled at the Liebherr facility in Biberach (Germany).

“A significant number of units are targeted to be in the field within the coming years. This will be a strong contribution to reduce CO2 emissions worldwide by using overall high-efficiency equipment, which, complementary to renewable energy sources, will provide and support a stable energy supply”, explained Alejandro Held, Sales Director Power Generation at Liebherr-Components AG.

Liebherr expects to supply the first engine units already in 2020. Prototype and pre-series units have been tested commonly at Cummins facilities in the UK to validate the generator set configurations also in accordance with grid codes compliance standards.

This new collaboration between Cummins and Liebherr is one further example of a long-lasting partnership. For more than three decades, Liebherr has been using Cummins turbochargers. Furthermore, many Liebherr machines, such as material handling and earthmoving machines, as well as mobile cranes are equipped with Cummins engines that complement Liebherr engine portfolio.
