The Allen Hydroscav Oil Purifier system (AHS) uses filtration
and thermal dehydration to remove solids and moisture
from almost all types of oils including lubrication,
hydraulic, synthetic, compressor, diesel fuel, vegetable,
and gear oils. The AHS can remove 100% of free and emulsified
water down to 50 wppm. The AHS is equipped to remove
solid particles down to 5 μm, as well as remove 100%
of dissolved hydrocarbon gases and air trapped in the oil.
The AHS is designed with programmable logic controls
for continuous and unattended operation. The AHS comes
pre-wired, pre-piped, and has a compact frame which allows
for easy installation and accessibility of components
for servicing. The AHS is the most efficient and productive
oil purifier on the market today. As the industry leader in
oil purification, the AHS is the most cost-effective solution
for great purification, extending the life of the oil and
the capital equipment that oil protects.
