128KW/140KW Cummins C175D5B Silent Diesel Generator - Industrial-Grade Power Solution

Alternative gas fuels have different calorific values and contain pollutants, which leads to varying specific requirements for gas engines. The design of Cummins rarefied gas generator sets fully considers this feature, providing powerful and reliable performance while meeting different fuel requirements. Furthermore, the Cummins full range of lean combustion gas generator sets covers a variety of rated powers and configurations, and each model can be configured according to the customer's on-site application, fuel type, and power requirements to achieve optimal performance and the strongest reliability.

The Cummins C175D5B is a fully integrated three-phase diesel generator, engineered for both standby and prime power applications. With a standby rating of 55 kVA/44 kW and prime power of 50 kVA/40 kW at 50 Hz (1500 rpm), it delivers stable electricity for commercial, industrial, and residential scenarios-from construction sites and data centers to remote settlements and hospitals.
Powered by Cummins' 4BTA3.9-G2 heavy-duty engine (3.9L displacement, 4-cylinder inline design), the C55D5 features turbocharging and water-air intercooling, ensuring efficient combustion and rapid load response. Paired with a brushless Stamford UC224D alternator (H-class insulation, IP23 protection), it minimizes waveform distortion (<5% under balanced load) and maintains voltage stability (±1% steady-state deviation).

Exceptional Reliability & Durability: Constructed with a robust cast iron cylinder block, forged steel crankshaft, and high-quality alloy components, the generator is built to withstand long hours of continuous operation and harsh working conditions-ideal for critical applications where downtime is intolerable. Equipped with Cummins' advanced PowerCommand control system, it enables automatic start/stop, real-time remote monitoring, and comprehensive protection against low oil pressure, high coolant temperature, overcurrent, and voltage fluctuations, ensuring 100% load acceptance within seconds and consistent performance even in extreme environments.

Superior Fuel Efficiency & Cost Savings: The optimized high-pressure common rail fuel injection system precisely controls fuel delivery, reducing fuel consumption to just 12 L/h at 100% load and 8.6 L/h at 75% load (its most efficient operating range). A large 200L integrated base fuel tank supports over 14 hours of uninterrupted runtime at full load, minimizing refueling frequency and operational costs. Additionally, the engine's long service intervals (500 hours for routine maintenance) and low wear design lower overall maintenance expenses, delivering long-term cost-effectiveness for users.

Compliance & Low Environmental Impact: Fully certified to ISO 8528 (for generator set performance), CE, and UKCA standards, the C55D5 meets strict Stage IIIA emission regulations, ensuring compliance with global environmental requirements. The optional sound-attenuated enclosure features advanced acoustic insulation materials and a low-noise fan design, reducing operating noise to 64 dBA at 7m-well within EU 2000/14/EC noise limits, making it suitable for urban, residential, or noise-sensitive areas without disrupting surroundings.

Global Service Support & Flexibility: Backed by Cummins' extensive global service network-with thousands of authorized service centers and trained technicians worldwide-the C55D5 offers a 5-year warranty for standby use and a 2-year warranty for prime use, providing users with peace of mind. 24/7 parts supply and emergency maintenance support ensure quick resolution of any issues. Moreover, flexible configurations are available, including extended fuel tanks (up to 1000L), automatic transfer switches (ATS), weatherproof enclosures for outdoor use, and cold-start kits for low-temperature environments, adapting to diverse power needs across industries.
