Heavy Industrial Prime Power with Common-Rail Engine Precision

The CDP250KW is Jiuan Generator's 250KW Perkins diesel generator for mining surface infrastructure, bulk mineral processing, and large industrial campus prime power. Rated at 250KW/312.5KVA ISO8528 PRP prime and 275KW/344KVA ISO8528 ESP standby, the CDP250KW is built for unrestricted continuous operation at rated load within a ≤70% average load factor — the ISO8528 standard that defines genuine prime power capability, distinct from engines derated from standby-only ratings. Applications include crushing-plant motor circuits, conveyor drives, site dewatering pumps, and welfare camp infrastructure at remote industrial sites where grid power is unavailable or unreliable.

The Perkins 1706A-E93TAG2 genset engine is a six-cylinder, four-stroke, water-cooled unit with 9.29L displacement, 115mm × 149mm bore and stroke, and a 16.5:1 compression ratio. The 1706A-E93TAG2 uses electronic high-pressure common-rail fuel injection with ECM electronic governor control — metering fuel electronically per cylinder per injection event, compared to the camshaft-driven mechanical injection used in smaller Perkins 1100-series engines. This delivers sub-cycle load-step response and reduced smoke output under sudden load changes, including crusher motor inrush. Fuel consumption at 1500 RPM (50Hz): 52.3 L/h at 100% prime load, 38.7 L/h at 75% load, 26.5 L/h at 50% load. Cold start: -15°C without aids. EU Stage II / EPA Tier 2 certified for global deployment.

The brushless synchronous alternator uses H-class insulation with IP23 protection (IP55 optional), maintaining ±1% voltage regulation and THD below 5% under steady-state operation. For the 312KVA prime power generator CDP250KW, Jiuan Generator installs a Deep Sea DSE7320 or SmartGen HGM6120 controller with AMF auto-start, ATS transfer switching, and independent per-phase voltage and current monitoring — essential for industrial distribution panels with asymmetric motor loads where per-phase protection prevents undetected single-phase overload. Optional 4G remote monitoring supports start-stop control and fault alerting for unattended remote installations.

Three enclosure formats are available for the 250KW heavy duty generator CDP250KW. The open-frame configuration uses a reinforced steel base with anti-vibration mounts, providing direct heat dissipation and full service access for generator room and covered plant room installations. The super silent canopy achieves ≤75dB(A) at 7 meters using high-density acoustic foam and an oversized industrial muffler, meeting noise standards for urban-adjacent processing plants, cement works, and portside facilities. The containerized format provides dust, rain, and salt-spray protection for coastal, mining, and tropical off-grid field deployment without a fixed generator building. The 500L integrated base tank supports 9+ hours of full prime-load operation on a single fill.

The Perkins 1700 series generator 1706A-E93TAG2 engine is rated for a 500-hour planned oil service interval — at a 10-hour daily run time, approximately 50 working days between scheduled maintenance visits. All consumable parts (filter kits, belts, and injectors) are available through Perkins' global distribution network in over 180 countries, covering the primary deployment regions for the CDP250KW: Sub-Saharan Africa, Southeast Asia, the Middle East, and Latin America. Jiuan Generator assembles each unit to ISO 9001 procedures and conducts a full-load factory burn-in test before dispatch; 18-month or 2,000-hour warranty is included.

Technical Specifications

5 Core Competitive Advantages

1. ECM Common-Rail Fuel Injection — Precise Per-Cylinder Fuel Metering for Transient Load Recovery
The 250KW Perkins diesel generator CDP250KW uses Perkins 1706A-E93TAG2 common-rail injection with ECM electronic governor control. Each injector fires electronically per cylinder per event — delivering sub-cycle fuel delivery response under sudden motor-start load pickup and crusher inrush, where mechanical injection systems exhibit fuelling lag from rack-travel dynamics. Faster fuel delivery means faster voltage and speed recovery after load transients, reducing under-frequency protection trips on sensitive process equipment.

2. 9.29L Displacement Reserve — Continuous Rated-Load Prime Operation Without Thermal Overstress
The Perkins 1706A-E93TAG2 genset 9.29L block produces 250KW prime at a specific output of 26.9 KW/L — a conservative loading that retains thermal reserve for unrestricted ISO8528 PRP operation at rated load. Engines sized too close to their peak cylinder pressure deliver rated power at elevated bore stress, accelerating ring and liner wear in continuous-duty applications. The 1706A-E93TAG2's displacement is sized to maintain this headroom across extended 24/7 prime power cycles.

3. 500L Fuel Tank — Full Operating Shift Autonomy for Remote Site Logistics
The CDP250KW 312KVA prime power generator carries a 500L integrated base tank. At 52.3 L/h full prime-load consumption, this covers 9.5 hours of uninterrupted operation on a single fill — sufficient for a full 10-hour site operating day with a small reserve margin. For remote mining and processing sites where diesel refuelling requires a tanker delivery vehicle, each additional tank fill avoided directly reduces logistics cost and operational interruption frequency.

4. Per-Phase Current Monitoring — Asymmetric Load Protection for Industrial Distribution Panels
The DSE7320 controller on the 250KW heavy duty generator CDP250KW monitors voltage and current independently on each output phase. For industrial sites running unbalanced three-phase motor loads across multiple distribution circuits, per-phase monitoring enables a targeted protective relay trip on the overloaded phase — maintaining power on the other two phases while isolating the fault, rather than a full three-phase de-energisation that would shut down the entire site load.

5. 500-Hour Service Interval — Extended Maintenance Cycle for Remote Site Cost Control
The Perkins 1700 series generator 1706A-E93TAG2 engine is rated for 500-hour planned oil service intervals. At a 10-hour daily run time, this equates to approximately 50 working days between scheduled maintenance visits — roughly double the 250-hour cycles required by smaller or higher-specific-output engines. For remote mine sites and processing facilities, halving the number of technician mobilisations per year directly reduces travel, accommodation, and service call costs over the generator's operating life.

Application Scenarios

The CDP250KW 250KW heavy duty generator is deployed across the following prime and standby power applications:

• Mining surface infrastructure — prime power for jaw crusher drives, conveyor motors, dewatering pumps, and welfare camp systems

• Industrial manufacturing plants — standby and prime power for process lines and compressed air systems
• Large commercial complexes and retail parks — standby power for HVAC, elevators, and fire safety systems
• Data centres and telecom clusters — standby power for high-density compute infrastructure requiring precise voltage regulation
• Remote construction camp infrastructure — prime power for accommodation, catering equipment, lighting, and security
