Cooling Parts

The thermostat acts as an intelligent temperature control valve in the engine cooling system, directly impacting equipment power output and service life. We supply OEM-grade thermostat solutions exclusively for classic Cummins models including NT855, K19, K38 and K50. Equipped with high-precision wax thermal sensing elements and corrosion-resistant alloy housings, our thermostats operate stably under extreme working conditions ranging from -40℃ to 120℃, supporting efficient operation of machinery in mining, marine, generator set and other industries.

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.

Jacket Water Heaters serve as the "pacemaker for cold startup" of diesel generator sets and construction machinery under low-temperature conditions. We supply OEM-grade jacket water heater solutions for large-displacement Cummins engines including NT855, K19 and K38.By submerging the heating element into coolant, the unit maintains the engine block at an optimal standby temperature of 38℃–45℃. It thoroughly eliminates cold start difficulty, incomplete combustion and oil emulsification issues, making it an essential component for critical backup power systems in data centers, hospitals, mines and other facilities.

Heat exchangers (oil coolers) act as the external kidney of the engine lubrication system, directly governing oil viscosity stability and overall engine service life.We supply OEM-grade complete heat exchanger assemblies and core elements for classic high-horsepower Cummins models including NT855, K19 and K38. Manufactured with premium copper or stainless steel heat exchange tubes and anti-cavitation coating, our products deliver efficient oil cooling under heavy-load and high-temperature operating conditions. They eliminate the risk of oil-water mixing, supporting continuous efficient operation of generator sets, marine vessels and construction machinery.

Within the harsh operating environment of engines, the cooling system serves as the lifeline that sustains efficient and stable operation. As the core driving component of the cooling system, the fan’s performance directly governs heat dissipation efficiency and overall engine reliability.We supply a full range of OEM and high-quality aftermarket engine fans for Cummins. Each fan is optimized for the unique working conditions of various models including NT855, 6BT, K19 and K38, ensuring every piece of equipment delivers consistent powerful power output at optimal operating temperatures.
