The Allen Coalescer-Separator system (ACS) is designed
to dehydrate and filter water, solids, sludge, and gases
on many different types of fluids. The ACS removes free
and emulsified water down to the saturation level. The
type of oil used, the kinds of additives in the oil, and the
temperature of the oil determines the saturation level. For
a typical ISO 32 turbine light oil at 100°F (37.8°C), the saturation
level is approximately 150 wppm. The ACS uses a
combination of coalescer and separator filter elements designed
to provide the most efficient filtration possible. It
comes equipped with an automatic water drain trap that
allows for continuous removal of water while the unit is
in full operation. The complete ACS System consists of a
pump/motor, pre-filter vessel, a coalescer-separator vessel,
and an optional final filter. The ACS is also available
individually as the coalescer-separator vessel only. For
clean, dry fluids the ACS provides a proven solution that
quickly pays for itself.
