Hydraulic oil coolers are used to cool the oil within the hydraulic system. It is important to maintain the correct temperature as this keeps the oil at the correct viscosity. The continuous flow of fluid through the system and the friction between system components increase the heat of the fluid, thus then can cause problems like the risk of cavitation and internal leakages and reducing the lifespan of the system. Hydraulic fluid will generate heat when in a mechanical system. Hydraulic oil temperatures above 180°F damage most seal compounds and accelerate the degradation of the oil.
