In industrial and supply applications, around 80% of the cost of hydraulic maintenance results from contamination, from leakage, or from the use of unsuitable fluids. In normal applications, more than half the hydraulic systems are highly contaminated and are directly responsible for over 2/3 of the total maintenance cost. Applying the know-how of La Ricambi Udinese and Controils, it is possible to reduce maintenance costs drastically.
