Cummins KTA50
The Cummins KTA50 radiator is an engineered cooling component exclusively developed to match the thermal management demands of the Cummins KTA50 diesel engine—a high-displacement, high-power unit widely used in heavy-duty industrial, marine, and mobile applications. Its core function is to efficiently dissipate massive heat generated by the KTA50 engine during continuous high-load operation, ensuring the engine maintains a stable optimal temperature range and avoiding performance degradation or component damage caused by overheating.
Features
High-Efficiency Heat Transfer: Adopts 99.9% high-purity oxygen-free copper tubes paired with high-density louvered aluminum fins. Precision mechanical tube expansion ensures 100% tube-fin contact, minimizing thermal resistance and delivering 35% higher heat dissipation than generic radiators—ideal for the KTA50's high heat output.

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.
Robust Protective Packaging – Radiators are packed in sturdy reinforced wooden crates, lined with moisture-proof material.
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.
Fin-tube assemblies utilize high-precision mechanical tube expansion to bond louvered copper fins with seamless copper tubes. This process ensures 100% fin-to-tube contact, minimizing thermal resistance, while boasting a 40% larger heat transfer surface area compared to standard assemblies.
Vacuum brazing—using copper-phosphorus filler metal—forges airtight copper joints that withstand repeated thermal expansion cycles. For added durability, critical header-to-tube connections receive additional reinforcement via argon arc welding, effectively preventing leakage caused by operational vibration.
