D9612
Power generation
Highlights
Designed and manufactured by Liebherr, the D9612 is a high performance combustion engine engineered for missioncritical power generation applications, particularly wellsuited for PRP and COP operations, while also supporting standby power requirements in stationary and mobile installations, including data centers. Built on a robust platform and backed by Liebherr’s proven engineering expertise, this 12 cylinder, 27 litre engine delivers up to 1,100 kW, providing stable and predictable performance across PRP and COP duty cycles under demanding operating conditions. Combining reliable efficiency with optimised fuel consumption and controlled emissions performance, the D9612 is designed to deliver dependable and costeffective power generation for missioncritical applications. Rapid load acceptance and controlled transient response secure compliance with ISO 85285 and NFPA 110 requirements, while extended service intervals, simplified maintenance and advanced diagnostics with LiDIA maximise reliability, minimise downtime and protect longterm asset value.
