An oil cooler is a crucial component in construction machinery, used to cool various mechanical parts, including the engine and transmission system, using oil. Hydraulic oil coolers and water radiators are available for a range of construction equipment, including diggers, dumpers, excavators, telescopic handler forklifts, and backhoe loaders. The choice of oil cooler can directly impact the cooling efficiency of the main engine cooling system, noise levels, fuel economy, and engine power consumption.
