Cummins High-Horsepower Engine Radiators
Radiators act as the core component of diesel engine cooling systems, directly determining the continuous operation capacity of equipment under heavy-load and high-temperature conditions. We supply OEM-grade complete radiator assemblies and core solutions for classic high-horsepower Cummins models including NT855, K19, K38 and K50.Constructed with high-purity all-copper or thickened aluminum cooling cores and manufactured via vacuum brazing technology, our radiators boost heat dissipation efficiency by over 30%. They effectively prevent overheating boil-over and high-temperature shutdowns, serving as reliable cooling support for mining equipment, marine vessels, power stations and construction machinery.

Core Advantages
Detailed explanation of machine model adaptation
BreakdownNT855 Series
- Applicable Engines: NT855, NTA855, NT855-GA (Generator Sets, Bulldozers, Excavators)
- Core Part Numbers: 4061029 (sample), 3013612
- Technical Highlights: Custom-engineered for the high-torque characteristics of NT855 engines with enlarged radiator tanks. It eliminates heat dissipation bottlenecks during prolonged heavy-duty operations such as earthmoving and rock crushing, preventing power degradation caused by excessive operating temperature.
K19 Series Radiators
- Applicable Engines: K19, KTA19, K19-G4/G6A (400kW–500kW generator sets)
- Core Part Numbers: 4061029 (K19 dedicated), 3056549 associated components
- Technical Highlights: Developed to handle the high thermal load of K19 inline 6-cylinder engines, it adopts an widened all-copper core with a 20% larger heat dissipation area. It fully meets the matching requirements of generator set assemblers including Topcore and Taihao.
K38 / K50 Series Radiators
- Applicable Engines:K38 & KTA38 (Marine Vessels / 800kW Generator Sets); K50 & KTA50 (1000kW+ Power Units / Mining Trucks)
- Core Part Numbers: 3638360 (For K38), 3065432 (For K50)
- Technical Highlights:This heavy-duty radiator is engineered exclusively for V-type 12/16-cylinder high-horsepower engines. It features a dual-layer flow channel design and thickened water tanks, capable of withstanding extremely high coolant pressure and flow rates. It maintains stable water temperature for large power units under full-load operation and completely eliminates thermal power attenuation.

Application Scenarios & Customer Testimonials
- Wind Power Industry:For K19 generator sets at a wind farm in Northwest China: The original aluminum radiators suffered corrosion and leakage after only 2 years of service. After replacement with our full-copper radiators, the units have run flawlessly for 3 consecutive years under high-temperature and heavy sand dust conditions with zero breakdowns.
- Mining Industry:For K50 mining haul trucks at a copper mine: The vehicles operate nonstop under extreme ambient temperature up to 40°C. Equipped with our heavy-duty dedicated radiators for K50, engine water temperature is consistently kept below 90°C with no overheating alarms during full-load operation.
