OLSW Features
The OffLine Separator Water OLSW is used to remove oil from water-based
washing liquids, which are contaminated with mineral oils (density < 900
kg/m³).
Coalescing procedure
The dewatering works according to the coalescence principle, during which
the oil collects on the fibers of the coalescing element and is conveyed
deeper into the coalescing element by the fluid flow. Smaller drops unite to
form larger ones at the fiber nodes during this process. Large oil drops climb
upwards and can be removed from the system by opening a valve.
The application is used in the bypass flow. The use of a micro-filtration
system is expedient to ensure the maximum possible service life of the
coalescing elements.
Limits of the coalescing procedure
The filter housing is unsuitable for the separation of oils whose density is
higher than 900 kg/m3, such as ester-based liquids and polyglycols.

OLSW Features
OLSW en(us) Page 17 / 44
MoWa OLSW 3587900a en-us 2018-08-17.docx
2018-08-17
The coalescing elements must be protected from contaminant particles by a
pre-filter so that the transport of oil drops is not obstructed by contaminant
particles.
HYDAC recommends the use of a WombatFilter WBF as pre-
filter. For details, see www.hydac.com.
Restrictions Pertaining
NOTICE
