There are many underlying factors working in the background that, alone or in tandem reduce hydraulic system efficiency and drain overall profitability. To counteract, Parker is offering you a pre-assessment of your hydraulic system's efficiency, providing a free temperature test kit. This will help to identify where excessive heat could be costing you money for:
greater maintenance costs,
reduced productivity, and
increased energy bills.

Watch the video and see the problems associated with excessive temperatures in a fluid tank and how to use the temperature test kit to identify if there are potential savings to be made on your hydraulic systems.
How can temperature control impact your profitability?
Under-estimation of heat dissipation – wrong assumptions of hydraulic cycles, neglected exothermic function of hydro-pneumatic accumulators, lamination or friction not properly calculated – lead to hydraulic fluid stabilizing at higher temperatures than expected. Despite progress made by oil industries to improve the performance of mineral oils and other fluids at elevated temperatures, the fluid lubrication capability will likely decrease.
Consequently, mechanical parts in motion will wear at an accelerated rate. This generates particles; impacting oil cleanliness and will start damaging servo valves and sensitive hydraulic components. The cycle continues: the more components get eroded the more abrasive the fluid becomes. The direct consequence is the impact on hydraulic component lifetime. Moreover, continuous operation at high temperature stimulates aging of rubber seals.
Eventually lower viscosity increases internal leakages, consequently, the system requires more power consumption for the same power output.
Owners risk facing unexpected leakages, reduced system efficiency, shorter interval between tank oil renewal or accumulators’ pre-charge controls, early product failures; those generating direct maintenance costs (human and material), loss of productivity and an increase of operational costs. Ultimately, a poor cooling design for a hydraulic installation impacts a customer’s business profitability.
