Cummins Powered Diesel Generator Sets

Engine Platforms We Build On

The Cummins engine family we use spans the 4B, 6B, 6C, L, M, N, K and QSK platforms. Turbocharging, intercooling and high-pressure electronic injection are applied across the range, giving low vibration, low noise and an engine overhaul interval of up to 20,000 hours. Units operate from -40°C to +50°C and at altitudes up to 4000 m, including humid, salt-spray and dusty environments.

• 4B / 6B / 6C platforms: compact four- and six-cylinder units for standby and prime duty in shops, offices, telecom stations and small industrial loads.
• L and M platforms: mid-range six-cylinder units for factories, hotels, hospitals, data halls and mine sites.
• N, K and QSK platforms: high-output units for large data centers, industrial parks, power plants, ports, offshore and oil & gas projects.

Power Range and Application Fit

We size the set against the actual load, not only the nameplate figure. Standby, prime and continuous ratings are quoted separately, and the proposal states which rating applies to your duty cycle.

Core Configuration of a Cummins Powered Set

Alternator

Brushless self-excited synchronous alternators with Class H insulation and IP22–IP23 protection. The maintenance-free design keeps waveform distortion low and holds voltage and frequency stable under both conventional and precision electrical loads, including the dynamic response needed for motor starting and UPS-backed IT loads.

Control System

LCD intelligent controllers provide real-time monitoring and full-range protection against overload, overheat and low oil pressure. Automatic start/stop, ATS power transfer, remote monitoring and cloud management support 24/7 unattended operation. Deep Sea, SmartGen and ComAp controllers are available, or a control scheme matched to your existing line interface.

Auxiliary System

Each set is delivered with a professional cooling system, triple filtration, heavy-duty vibration dampers, a high-efficiency muffler and an integrated base frame. This combination keeps installation simple and supports long-term stable operation without field fabrication of mounting or exhaust components.

Performance Data That Shapes Selection

• Fuel consumption: 197–210 g/kWh across the range, with an optimised combustion system for full fuel burn.
• Load acceptance: up to 80% sudden load pickup, giving strong power reserve for step loads.
• Startup: ultra-fast start within 3 seconds with seamless ATS switching.
• Noise: silent and container-type units achieve below 75 dB(A).
• Emissions: China Stage III, Euro II/III and EPA Tier 2–4 configurations.

Structural Options and Deployment

The same Cummins engine and alternator package is available in several build forms, so the enclosure decision follows the site rather than the other way round.

• Open Type Diesel Generator Sets for plant rooms with dedicated acoustic treatment and easy service access.
• Silent Type Diesel Generator Sets for urban, hospital and hotel sites with noise limits.
• Trailer Type Diesel Generator Sets for field work, rental fleets and emergency rescue.
• Container Type Diesel Generator Sets for offshore, port and remote sites, including high-voltage 3.3 kV / 6 kV / 10 kV builds.

Multi-unit parallel operation is supported for capacity expansion, and the range sits alongside our other engine platforms, including Perkins Powered Diesel Generator Sets and Volvo Powered Diesel Generator Sets, when a project calls for a mixed fleet.

Optional Equipment and Customisation

• ATS automatic transfer switch and generator paralleling systems
• Remote monitoring and cloud management packages
• Silent canopy, soundproof box, mobile trailer, integrated container power station
• Dual-fuel system, low-temperature cold-start preheater, enlarged fuel tank
• Explosion-proof customisation for hazardous-area projects
• Professional O&M services and genuine spare parts supply

Quality Control and Acceptance Testing

Quality control runs through production rather than sitting at the end of the line. Incoming inspection of key components, assembly process verification, electrical safety checks and mechanical fitting inspection are applied at defined control points, so performance stays consistent across batches.

Before delivery, every set is validated through full load testing from 0 to 110% of rated capacity, step load response testing, continuous operation endurance testing, voltage and frequency stability testing, and emergency protection system verification. Documentation for the tested configuration is issued with the unit.

Installation, Maintenance and Serviceability

Installation guidance covers foundation and base-frame fixing, exhaust routing, cooling air path, fuel and cabling connections, and control interface wiring. We provide operation support and technical troubleshooting after commissioning, together with a stable supply of engine components, alternator parts, electrical and control system parts, filters and consumables.

• Triple filtration and accessible service points reduce routine maintenance time.
• Heavy-duty vibration dampers and integrated base frame limit alignment drift.
• Spare parts supply is planned alongside the project to reduce downtime risk.

Information We Use to Configure Your Solution

Frequently Asked Questions

What power range do your Cummins powered sets cover?

We build from 8 kW to 3750 kW, with prime and standby ratings quoted separately. The DCEC series covers the lower and mid bands, while the larger N, K and QSK platforms serve high-output continuous and parallel applications.

Can the set run unattended?

Yes. Automatic start/stop, ATS power transfer, remote monitoring and cloud management allow 24/7 unattended operation, with overload, overheat and low oil pressure protection active throughout.

Which enclosure should be specified for a noise-sensitive site?

Silent and container-type builds achieve below 75 dB(A). For plant rooms with existing acoustic treatment, an open type set with a high-efficiency muffler is often the more serviceable choice.

How is each unit tested before shipment?

Every set undergoes full load testing from 0 to 110% of rated capacity, step load response testing, continuous operation endurance testing, voltage and frequency stability testing, and emergency protection verification.

Do you support OEM and ODM builds?

We provide OEM and ODM manufacturing covering power configuration, engine selection, control system integration and structural design, with branded production available for distributors and project contractors.

What spare parts support is available after delivery?

We supply engine components, alternator parts, electrical and control system parts, filters and consumables, supported by installation guidance, operation support and technical troubleshooting.
