Memo:Changes in hydraulic fluid properties calls for an innovative approach to limit the negative impact of electro-static discharge in oils Fluid conductivity can impact system performance

Modern hydraulic oils of group II and III can have a lower Zinc content which reduces the fluid conductivity. Electro-static charging can occur everywhere in a system, but problems arise when the fluid conductivity is too low. In this situation the electro-static energy can accumulate and create discharges in the oil. As varnish can be formed due to thermal and oxidative degradation of the fluid, the discharge of electro-static energy can contribute to this process in a significant manner. Varnish can cause system damage and lowers its productivity due to blocking of flow paths in components like valves and coolers, causing plugging of filters and can result in dangerous situations developing such as contributing to valve malfunction.

Static-Free is a promise difficult to fulfill

As electro-static charging of the fluid can occur anywhere in the hydraulic circuit, Parker recommends not only reviewing the filters but the entire system. Parker is one of the few companies who can offer qualified support relating to system analysis and provide the most effective system components. For systems sensitive to the negative impact of electro-static charging of the oil, Parker offers the Static Control Media to upgrade existing filters or for filter assemblies used for new systems.

Improving system productivity and profitability

Parker’s Static Control Media reduces the electro-static charging on the oil. By evaluating the total system and implementing Static Control Media, life time of hydraulic fluids and system components can be extended. By reducing the negative impact of thermal oxidation, the amount of varnish created in the system is also reduced. This has a positive influence on the efficiency, and hence the productivity and profitability of the system.

Direct availability from Parker

Parkers HFDE500 products are selected from the total filter offering for the direct availability of the static control media from 1st October 2012. This range covers tank top mounted filters and in-line filters enabling system designers to select a suitable filter solution from Parker.
