Cummins QSK95-G4
Designed exclusively for the Cummins QSK95-G4 high - power engine (displacement: 95L, maximum power: 4,400 hp/3,281 kW), this radiator is engineered to deliver reliable heat dissipation performance, supporting the engine's stable operation in harsh industrial scenarios such as heavy - duty power generation, mining machinery, and railway locomotives.
Features
High - Efficiency Heat Dissipation: Dense fin structure + optimized airflow; quickly dissipates full - load heat, keeps coolant temp at 82 - 95°C to prevent overheating.
Precise Compatibility: Matches QSK95 - G4's mounting size, fluid port & 15 psi pressure; integrates seamlessly with closed - loop cooling system, no leakage.

Maintance and Service
Premium Components – Every component undergoes stringent multi-stage quality inspections—from raw material sampling to finished part testing—to ensure your equipment maintains continuous, trouble-free operation.
Tailored Cooling Solutions – We tailor-engineer radiators to match the exact specs of your engine and adapt to your specific operational environment, delivering targeted cooling performance that generic radiators can’t match.
Customized Solutions – We provide tailor-made cooling systems to meet the exact requirements of your engines and working environments.
How We Produce
Each generator radiator undergoes specialized CAD-based thermal flow simulation and structural stress analysis—calibrated to the high thermal conductivity of copper tubes—to optimize heat dissipation efficiency during the generator's continuous operation.
Our ISO 9001 - certified facility tests every radiator with strict leak, pressure, and thermal checks. This ensures delivered products have consistent quality, long durability, and reliable heat dissipation.
