Application Scope
- Data centers and telecom facilities
- Manufacturing plants and production lines
- Hospitals and large commercial buildings
- Mining and industrial prime power sites
Problems It Solves
- Adding a full megawatt of standby power without rebuilding the switchgear room
- Covering peak loads when the utility supply is capped
- N+1 redundancy for mission-critical facilities
- Prime power where the grid connection is weak or unavailable
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:
| No-load run | Warm-up, oil pressure and charging voltage check |
| 25% load, 30 min | Stability of voltage and frequency, exhaust temperature |
| 50% load, 30 min | Governor response, fuel consumption, noise level |
| 75% load, 60 min | Cooling system, coolant temperature, belt tension |
| 100% load, 60 min | Full rated output, voltage regulation within ±1.5% |
| Overload 110%, 1 min | Protective shutdown and alarm verification |
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.
