Cummins QSK78-G8
A purpose-built cooling component engineered exclusively for Cummins QSK78-G8 high-power diesel engines, this radiator delivers reliable heat dissipation to support the engine's 2500-3200kW output in heavy-duty industrial, mining, and power generation applications.
Features
Temperature Resilience: Operates efficiently at -30°C to 135°C (supports thermal cycles), matching Cummins QSK78-G8's 2500-3200kW output.
Durability: Pressure-resistant with TP2 deoxidized copper tubes; 100% tested (2.5MPa hydrostatic test, helium leak detection) + 5g vibration resistance.
System Compatibility: Integral set-mounted design fits Cummins QSK78-G8's cooling system; optional integrated oil cooler.

Maintance and Service
Custom Cooling Solutions – We engineer radiators precisely aligned with your unique engine requirements and operational environmental conditions.
Protective Packaging – Reinforced wooden crate with moisture-proof lining to prevent copper corrosion during transit.
How We Produce
Each generator radiator undergoes specialized CAD thermal flow simulation and structural stress analysis—tailored to the high thermal conductivity of copper tubes—to optimize heat dissipation efficiency under continuous generator operation.
Fin-tube assemblies adopt high-precision mechanical tube expansion technology to integrate louvered copper fins with seamless copper tubes—ensuring 100% contact between fin and tube for minimal thermal resistance, while maximizing heat transfer surface area by 40% compared to standard assemblies. Vacuum brazing (using copper-phosphorus brazing filler) creates airtight joints between copper components, withstanding repeated thermal expansion cycles; critical header-to-tube connections are further reinforced with argon arc welding to prevent vibration-induced leakage.
