RENOSAFE FIREPROTECT 68 FAM
Fire-resistant hydraulic fluid, based on new ester and additive technology, Type HFDU
Description
RENOSAFE FIREPROTECT 68 FAM is a fire-resistant hydraulic fluids based on special synthetic esters. The selected organic ester base oils have highest purity and show high oxidation hydrolytic and thermal stability. The properties of the fluids are improved by the addition of special selected zinc and ash-free additive systems. These zinc and ash-free additive systems are based on new additive technology which guarantees excellent copper compatibility, yellow metal compatibility, excellent hydrolytic stability, and highest oxidation stability. They contain very effective robust and stable wear protection additives together with extreme pressure components. RENOSAFE FIREPROTECT 68 FAM is non-toxic and physiologically harmless. It shows in comparison to mineral based hydraulic fluids higher flammability temperature and higher self-ignition temperature. Special flammability tests according to ISO 12922 demonstrate that RENOSAFE FIREPROTECT 68 FAM reduces the risk of violent explosion or flammability when the fluids come in contact with open flames or hot metal surfaces (in comparison with mineral based products). These special flammability tests are in accordance to the ISO specification 12922, group HFDU - fire resistant fluids. The flammability risk is tested when the fluid or the pressurized fluid comes in contact with open flames and hot surfaces. The test results show a significant reduction of flammability risk by using RENOSAFE FIREPROTECT 68 FAM.
RENOSAFE FIREPROTECT 68 FAM has a natural high shear stable viscosity index (multigrade characteristic). This high viscosity index (high VI) is based on the physical property of the base fluid. It does not contain viscosity index improver. It does not contain shear unstable additives. Therefore, it has a high natural shear stability. Special additive systems which are selected according to the properties of the base fluids (organic esters) guarantee high oxidation, hydrolytic, and ageing stability. RENOSAFE FIREPROTECT 68 FAM has excellent corrosion protection properties. It protects steel and non-iron metals from corrosion. The copper corrosion protection is guaranteed by the selection of a special copper/yellow metal passivator which gives protection over a wide application window. The anti-wear (AW) and the extreme pressure (EP) additives protect the hydraulic pumps and components against wear and against scuffing. The combination of selected additives in the fluid shows excellent low foaming and excellent air release properties. Entrained water can be separated easily. RENOSAFE FIREPROTECT 68 FAM is non-toxic, rapidly biodegradable (> 60% according to OECD 301 B), can be seen as physiologically harmless, and free of heavy metals. RENOSAFE FIREPROTECT 68 FAM surpasses all requirements according to ISO 12922 – (dated 2011), group HFDU.

Application
RENOSAFE FIREPROTECT 68 FAM can be recommended as a fire resistant hydraulic fluid - based on organic esters - type HFDU - for all hydraulic units, machines or plants operating in hazard conditions where naked flames or high temperatures are present and a risk of fire caused by a fluid leakage is high. using RENOSAFE FIREPROTECT 68 FAM, the flammability risk in comparison to mineral oil can be reduced. RENOSAFE FIREPROTECT 68 FAM has a higher flammability characteristic and higher ignition temperature, which reduce the risk of fire by leakage of the pressure fluids compared to mineral oil. Typical application: steel mill, blast furnaces, continuous casting machines, coke plants, mining application, mobile and stationary hydraulic units, injection molding machines. RENOSAFE FIREPROTECT 68 FAM guarantees a rapid biodegradability and reduce the environmental risk potential. The product is in general miscible and compatible with conventional hydraulic fluids based on mineral oils. In general, the compatibility of mineral based fluids and HFDU types can be examined according to the special FUCHS Inhouse compatibility procedure. A change to RENOSAFE FIREPROTECT 68 FAM fluid is possible at any time. Please contact the FUCHS technical assistance. The compatibility with seal materials, e.g. NBR, Viton, silicon seals is good whereas the use of neoprene, ethylene or propylene seals is not recommended. Before filling the hydraulic circuit with RENOSAFE FIREPROTECT 68 FAM, it is important to know whether miscibility and compatibility is given. It is recommended to check the compatibility of RENOSAFE FIREPROTECT 68 FAM with mineral oils and other ester-based fluids in a laboratory test. Contamination with water, steam should be avoided (please check the air filter of the circuit, bypass filter systems, water separators etc.). Recommended tank temperatures: 70 - 90 °C. The lower the temperature, the higher will be the lifetime - recommended permanent temperature should be 70 °C or lower. Temperatures of 90 °C or higher are tolerable for a period of time. Periodical control of the used product is recommended. Oil samples of used oil should be tested in the FUCHS laboratories. Our technical assistant will advise the customer on the best suggestions according to the test results.
