PLANTOFLUX-A T-S are fire resistant hydraulic fluids with self-extinguishing properties. PLAN-TOFLUX-A T- S are synthetic fluids formulated with organic esters and specifically selected additives. They do not con- tain mineral oils and are free from toxic and unpleas- ant smelling decomposition  products. PLANTOFLUX- AT-S have a higher flash and combustion point than traditional, mineral oil-based hydraulic oils and are specifically designed to reduce the risk of violent ex- plosion when in contact with open flames or hot metal surfaces.good lubrication performance in an extremely wide operating temperature range.The high viscosity index, constant at all time, providesPLANTOFLUX-A T-S  offer  high  oxidation  and  ageingresistance, excellent corrosion protection and anti- wear properties, low foaming tendency, rapid water separation and  consequently  reduction  of  water  and oil sludge.cluded in the CEC list of the hazardous products sub- ject to labelling.

 PLANTOFLUX-A T-S are primarily used as fire resis- tant hydraulic fluids in machines or plants operating in hazardous conditions, i.e. where naked flames or high temperatures are present and the fire risk caused by  the  fluid  leakage  is high,  most  notably: steel mills, blast furnaces, continuous casting ma- chine, coke plants, etc.PLANTOFLUX-A T-S are generally applicable in anyhydraulic systems where environmental protection and biodegradability are a priority.PLANTOFLUX-A T-S are  miscible  and  compati ble with conventional mineral oils, therefore a change to PLANTOFLUX-A T-S is possible at any time. Please contact our Technical Assistance. The compatibility with Nitrile, Teflon, Viton and Silicon elastomers is good, whereas the use of Neoprene, Ethylene- propylene, Butyl and  Isoprene  seals  and  hoses  is not commonly recommended.Before filling the hydraulic circuit with PLANTOFLUX-A T-S it is important to know whether the fluid used previously was a mineral oil, a phos- phate ester or a different one, such as water -glycol or inverted emulsion.1.Mineral oilOwing the miscibility and compatibility of PLANTOFLUX-A T-S with mineral oils, only drain- ing before replacement is required. In case of relevant presence in the hydraulic system of de- posits and sludge, a preliminary flushing with PLANTOFLUX-A T-S is recommended. Filters should be cleaned or replaced.2.Phosphate estersPLANTOFLUX-A T-S is miscible and compatible with phosphate esters, therefore the same pr o- cedure as for mineral oils can be followed.The compatibility with PLANTOFLUX-A T-S of elastomer components, i.e. seals, hoses, etc., present in the system, must be controlled in ad- vance in the FUCHS' technical assistance labor a- tories.3.Other fluids (water base)Procedure for replacement is different depending on the fluid type. Please contact our technical department.PLANTOFLUX-A T-S fluids possess a very high oxi- dation resistance and are able to resist for a long time to thermic-oxidative  conditions,  without  suffe r- ing alterations of relevance. The joined action of metals, water and pollutant can accelerate the oxyen attack at high temperature, therefore, in order to get the best performances of the in-service fluid, it is advisable to maintain it well cleaned and free  of water.The temperature should not exceed 70°C  – 90°C inthe tank and in the operating parts of the hydraulic system. Temperature peaks of 90°C  are  tolerable only for a short period of time.A periodical control of the in-use product is recom- mended by means of samples  to  be  tested  in FUCHS' laboratories. Our Technical Assistance will advise the customer on the best suggestions ac- cording to the test results.
