Mobil Pyrotec™ HFD 46B is a high performance phosphate ester self-extinguishing fire resistant hydraulic fluid. Mobil Pyrotec HFD 46B is TXP-free.
Mobil Pyrotec HFD 46B has been evaluated in stringent tests for fire resistance such as the ISO 20823 manifold ignition test. Compared to other types of synthetic or mineral fire resistant fluids, Mobil Pyrotec HFD 46B shows a much higher ignition temperature (greater than 700°C) and is very difficult to ignite. If ignited, the flame will self-extinguish.
Mobil Pyrotec HFD 46B is formulated from specially purified phosphate base stocks and additives providing improved oxidation stability and lubrication properties. Physical properties such as foaming, air release and demulsibility are controlled to meet the limits specified by turbine manufacturers.

Applications
Mobil Pyrotec HFD 46B is recommended for use in applications where fire safety is critical, such as:
- Electro-hydraulic governor control systems of steam turbines, especially where a high performance fluid is required,
- Hydraulic and oil circulation systems operating in conditions subject to fire hazards,
- Other applications such as gas turbines, turbo-compressors, reactor coolant pumps and generators.
Please note that Mobil Pyrotec HFD 46B is fully compatible with Mobil Pyrotec HFD 46.
Special precautions should be taken when using Mobil Pyrotec HFD 46B regarding:
- System operating temperatures: normal system temperature should be between 50 and 65°C to avoid water condensation and local spot temperatures should be kept below 150°C,
- Flushing procedure when replacing petroleum oils, conventional soluble emulsions, water in oil emulsions or water glycol fluids,
- Compatibility with elastomers (for example, Mobil Pyrotec HFD 46B is not recommended for use with Neoprene, nitrile and silicon materials but compatible with seals and hose materials such as butyl rubber and Viton),
- Compatibility with paints, enamels and varnishes (for example, Mobil Pyrotec HFD 46B is not recommended for acrylic, latex and phenolic resin paints but compatible for example with epoxy type paints).
