Cummins engine oil cooler , Iran

The Cummins engine oil cooler is manufactured as a plate type with parallel channels. The plate material is aluminum 6061 with thermal conductivity of 200 watts per meter-Kelvin. Each plate thickness in the standard model is 1.2 millimeters and the spacing between plates is 2.5 millimeters. The number of plates in the 6BT model equals 35 and in the NTA855 model equals 55. The total heat exchange surface area in the 6BT sample is calculated at approximately 0.45 square meters. This value in the NTA855 model reaches 0.85 square meters. The allowable working pressure of the oil cooler is 12 bar and the hydrostatic test pressure is 18 bar. The nominal oil flow rate in the 6BT model equals 35 liters per minute. This flow rate in the NTA855 model increases to 60 liters per minute. The incoming oil temperature reaches up to 130 degrees and the outgoing temperature after cooling drops to 95 degrees. A temperature difference of 35 degrees indicates an efficiency of 82 percent.

The Cummins oil cooler is capable of dissipating 25 to 45 kilowatts of heat from the engine oil. In construction machinery applications, maximum heat dissipation of 35 kilowatts is sufficient for 6-cylinder engines. Marine applications require 45 kilowatts dissipation because engine speed remains high. Generator applications at full load require 30 kilowatts dissipation. The oil pressure drop across the cooler is a maximum of 1.2 bar in the 6BT model. This pressure drop in the NTA855 model reaches 1.8 bar. The inlet and outlet connection diameter in the 6BT model equals 25 millimeters. The cooler body dimensions in the 6BT model are 180 by 120 by 75 millimeters. The NTA855 model has dimensions of 240 by 150 by 95 millimeters. The weight of the 6BT cooler is approximately 3.5 kilograms and the NTA855 sample weighs approximately 6.2 kilograms. The oil flow path inside the cooler is designed with 6 to 8 passes to increase heat exchange duration.You can order and buy Cummins engine oil cooler from Iran by contacting us through whatsaap and email.
