OLS Features
The OffLine Separator OLS is a dewatering unit for hydraulic oils, gear lubrication oil
and diesel fuels with densities below 950 kg/m3.
The OLS is installed in the bypass flow, but it can also be used as a transfer unit for
diesel fuel, optionally with a prefilter.
Coalescing procedure
The dewatering functions in accordance with the coalescence procedure, during
which water 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 fibre nodes during this process. Larger drops settle downwards and can be
drained off by opening a valve.
The coalescing process is mostly used in systems in which small quantities of free
water cause no damage or in which fluids are used which exhibit excellent
demulsifying properties (the capacity of rapidly giving off quantities of water with
which they have mixed).
Utilization in the bypass flow. The utilization of an extremely fine filtration system
upstream from the coalescing elements is useful for ensuring that they have as long
a service life as possible.
