WATER
GLYCOL FIRE RESISTANT HYDRAULIC FLUID
|
|
SELCO HYDROLUBES SF - 315 is fire-resistant,
water glycol (HF-C) based hydraulic fluids.
Their use as replacement for mineral oil fluids
is recommended whenever a major fire hazard
exists associated with industrial systems.
RECOMMENDED USAGE
SF-315 is primarily recommended in die
casting machines, hydraulic forging presses
and hammers, machines and drive systems in
the mining industry and robot welding machines.
Selco Hydraulic SF-315, with a typical water
content of 36% is particularly designed for
use in the metallurgical industry, where its
excellent lubricity characteristics are beneficial
in the heaviest operations (for e.g. in die
or continuous casting). Selco Hydrolube SF-316,
with a typical water content of 43%, is particularly
recommended for use in coal mining, where
the higher water content provides an extra
safety margin.SF-316, with a water content
of 43% fully meets the requirement of the
fifth Luxembourg report for coal mine service.
PROVEN BENEFITS
Superior fire resistance, excellent anti-wear
performance, low order of toxicity, compatible
with standard packings and seals, low pour
points, shear stability and good viscosity
indices.
