What is fire resistant hydraulic fluid?

Fire Resistant Fluids Less hazardous and more fire resistant hydraulic fluids are water glycols, water in oil emulsions, and synthetic fluids. Fire Resistant hydraulic fluids have been developed to replace petroleum-based fluids in applications where there is a potential ignition source.

Which is the most fire resistant hydraulic fluid?

water glycol fluids
HFC. HFC or water glycol fluids are the most widely used fire resistant hydraulic fluids because of their price-quality and their combination of fire resistant properties with reasonable lubrication performance.

Is water-based hydraulic fluid flammable?

Hydraulic fluids for the most part are considered to be much less flammable than middle distillate fuels. Petroleum-based hydraulic fluids have high flash points, while water-based hydraulic fluids (because of their high water content) are definitely nonflammable.

What is water-based hydraulic fluid?

Because water-based hydraulic fluid consists of 10 parts water and one part synthetic additive, 5 gal of additive mixes with water to make 100 gallons of water-based fluid. A 50-gal container is certainly easier to handle than two 55-gal drums, so warehousing is simpler, cleaner, and less cluttered.

What are three basic types of fire resistant fluids?

There are three main types of fire resistant hydraulic fluids:

• High Water Fluids.
• Water Glycols.
• Synthetics.

Can we use water in hydraulic system?

The water will reduce the strength of lubricating film and hence internal or external leakage will occur. Also, the water molecules will result in oxidation/corrosion of metal surfaces. The low boiling point and freezing point of water is another drawback of using water as a hydraulic fluid.

What is water glycol hydraulic fluid?

Water-glycol fluids contain from 35 to 60 percent water to provide the fire resistance, plus a glycol antifreeze such as ethylene, diethylene, or propylene which is nontoxic and biodegradable, and a thickener such as polyglycol to provide the required viscosity.

Why is hydraulic fluid so flammable?

Petroleum based hydraulic fluids like mineral oils have flash point(the lowest temperature at which the vapors will ignite) that ranges from 300 to 600 degrees Fahrenheit. The water-based hydraulic fluids are inflammable.

Is hydraulic fluid and hydraulic oil the same?

What is hydraulic oil? Hydraulic oil is a non-compressible fluid that is used to transfer power within hydraulic machinery and equipment. Otherwise known as hydraulic fluid, hydraulic oil can be synthetic- or mineral-based. At Crown Oil, as a hydraulic oil supplier, we deal with 99% of mineral-based hydraulic oils.

Why is water not a good hydraulic fluid?

Which type of fire resistant hydraulic fluid is best for high temperature operation?

Water Glycol Fluids offer excellent fire resistant properties, due to its high water content.
