Cummins 450kW Open Diesel Generator

Key Specifications

Features

• Cummins KTA19-G8E inline-six engine, 19 L displacement, 1500 rpm, turbocharged with electronic injection speed control
• 450 kW prime / 500 kW standby at 400/230 V, 50 Hz, rated current 810 A
• KCI-450 brushless synchronous alternator, IP23 protection, Class H insulation, copper winding, self-excited AVR regulation
• Closed-loop water cooling; steady-state voltage regulation ≤0.5%, transient voltage deviation ≤15%, voltage and frequency recovery within ≤3 s
• Open steel skid with anti-vibration mounts and forklift points, suitable for dedicated plant rooms or later silent-canopy conversion

Application Scope

• Manufacturing plants and process lines
• Water treatment works and pumping stations
• Commercial buildings, schools and logistics facilities
• Remote prime-power sites and backup for processing equipment

Problems It Solves

• Supplying 450 kW continuous or 500 kW standby load from one proven Cummins skid
• Keeping process equipment running when utility supply fails or is current-capped
• Balancing reliable output with compact dimensions of 3300 × 1400 × 1970 mm
• Building a room-ready open set that can later receive a silent canopy without changing the core frame

Manufacturing & Quality Testing

Every Kaichen diesel generator set passes through the same production line and test routine before it leaves our factory in Jiangsu. The process is built around one goal: the set arrives at your site ready to carry load on the first real outage, not after a month of debugging.

How each set is built

• Engine and alternator matching. We match the engine rating to the alternator at the exact power factor your site needs, not just at the nameplate number.
• Baseframe and tank. The skid is welded from steel plate, fitted with an integrated fuel tank, vibration isolators, and forklift slots before the engine is mounted.
• Wiring and control panel. Power and control wiring are routed in separate channels, terminal blocks are numbered, and the digital controller is pre-programmed for your voltage, frequency and ATS logic.
• Canopy or container. Silent sets are dressed with acoustic foam, vented panels and access doors; containerized sets receive weather-sealed doors, internal lighting and a socket for external power.

Load test before shipment

No set ships on a visual check. Each unit runs on our electronic load bank for a structured sequence, and the test report travels with the set:

Final inspection

• Insulation resistance and earth continuity tested after a damp-heat soak.
• All protective functions verified: over-speed, high water temperature, low oil pressure, over-current, emergency stop.
• Automatic transfer switch sequence tested end-to-end on a bench.
• Paint touch-up, cleaning, and a full spare-parts list packed in the toolbox.

CE and ISO 9001 certificates accompany each shipment. If you need a witness test, a third-party inspection (BV, SGS, TUV) report, or a site-specific FAT protocol, tell us before the set enters production and we will prepare it accordingly.
