Fire-Resistant Hydraulic Fluids for High Temperatures and Extreme ConditionsHoughton International is the world’s largest and fastest-

growing producer of fire-resistant (FR) hydraulic fluids.

Houghton began developing fire-resistant hydraulic

fluids in the early 1950s in response to industry’s

movement to provide a greater level of operating

safety in hydraulic systems. It quickly became evident

that conventional petroleum-based hydraulic oils were

potential hazards when leaks, line ruptures or other

mechanical failures exposed them to ignition sources.

Houghton’s fire-resistant hydraulic fluids reduce

the risk of combustion. Seven decades of use

worldwide have proven them to be safe, reliable,

economical and environmentally friendly.

Today, Houghton ships more than 20 million gallons

of FR hydraulic fluids a year and has an installed base

of 200 million gallons in a wide variety of industrial

hydraulic equipment.

Houghton backs its products with extensive

ongoing technology and lab support services.

We are the only manufacturer to offer every

type of water-based and anhydrous FR hydraulic fluid,

including water glycols, high water content fluids

(HWCF), polyol esters, phosphate esters and vegetable

oil-based products. And our products are approved by

Factory Mutual Insurance Company for fire resistance.

Houghton FR hydraulic fluids help:

• Reduce operating costs, increase plant efficiency,

and extend equipment life.

• Meet and/or exceed fire safety regulations

and improve employee and plant safety.

• Reduce insurance premiums.

• Significantly reduce long-term fluid costs.

These products are used in numerous applications

including automotive, food and beverage, foundry,

die casting, steel processing, non-ferrous production

and mining. Cosmolubric HF-130 and Cosmolubric

B-230 are approved by the Mine Safety and Health

Administration (MSHA).

Anhydrous Fire-Resistant Hydraulic Fluids (HFD)Houghton anhydrous fluids are based on high-

quality esters and formulated with antioxidants to be

thermally and chemically stable, ensuring excellent fluid

performance and long life without system change-out.

Cosmolubric® HF Series Polyol Esters (HFDU)

Cosmolubric® HF Series fluids are synthetic polyol ester

hydraulic fluids that are chemically and thermally stable.

They are designed for long service life and dependable

performance in areas where a less flammable hydraulic

fluid is required. The additive package in these fluids

provides the best possible mechanical performance,

providing corrosion protection, metal passivation,

hydrolytic stability and oxidation inhibition. These

products are available in two viscosity grades:

ISOVG46andISOVG68.

Cosmolubric® B Series Vegetable Oil-Based Fluids

Cosmolubric® B Series fluids are the latest development

in our line of fire-resistant hydraulic fluids. Derived

from vegetable oils, these fluids are fire resistant and

formulated to enhance corrosion protection, metal

passivation and oxidation inhibition, even when abused

in service. They are primarily composed of renewable

source materials and are therefore USDA-certified as

bio-based products. These products have virtually zero

toxicity to the environment and aquatic life, making them

ideal for outdoor mobile hydraulic equipment and other

environmentally sensitive equipment. Cosmolubric B Series

products have passed Vickers 35VQ mobile equipment

pump test and FZG load stage 12 test, making our B Series

well suited for rolling mill automatic gauge control

systems, coilers and continuous casting equipment.

Houghto-Safe® 1000 Series Phosphate Esters (HFDR)

Houghto-Safe® 1000 Series fluids are phosphate

ester fluids that display excellent lubricating properties

and operate at high pressures and at temperatures up to

150 °F. They are Factory Mutual-approved for operation

in all types of pumps and hydraulic components.

Water-Based Fire-Resistant Hydraulic FluidsWater-based fluids are the most cost-effective

option for hydraulic equipment. Metal producers

and food processors choose Houghton water glycols

because they are extremely stable and can be used

at lower ambient temperatures.

Houghto-Safe® Water Glycol Fluids (HFC)

Steel producers, automobile manufacturers

and food processors around the world choose

Factory Mutual-approved Houghto-Safe® water

glycols because they provide the optimum

combination of fire resistance, performance

and economy.

Houghton has developed a variety of water

glycol fluids for specific industry needs, including

fluidsthatmeetMilitarySpecificationMIL-H-22072

and fluids approved for incidental food contact.

These products can be used in applications well

below freezing.

Hydrolubric® High Water Content Fluids (HFA)

Hydrolubric® 120 Series products are synthetic water

additives designed to meet the needs of central

water systems using reciprocating plunger, multi-

stage centrifugal or multi-stage gear pumps.

The polarity of the synthetic components in these

products provides a film on metal surfaces that

effectively reduces friction coefficients, enhancing

lubricity and protecting against aqueous corrosion.

Shipped as concentrates, they are:

• Typically used at 2% – 5% concentration.

• Readily dispersible in water.

• Biodegradable, offering advantages in

handling and disposal when compared

to conventional soluble oils.

These products are frequently used in steel mills,

foundries and automotive tire production. When

subjected to winter ambient temperatures, anti-

freeze protection can be applied.
