MBL Solvancer

Mobil™ Solvancer is an oil-soluble cleaner blended from Group V
base stock, and is compatible with most lubricants formulated with
API Group I – Group IV base stocks. A concentration of 3-5% of
Mobil Solvancer in the system oil is typically recommended. It can
be added to in-service oil without adverse impact to performance,
unlike water based chemical cleaners or some aggressive oil
soluble cleaners. Use of Mobil Solvancer typically does not require
a secondary displacement flush. It is recommended for use
during 1) oil conversions; 2) to alleviate operational issues due to
varnish, such as elevated bearing temperatures or sticking valves;
or 3) to support oil life extension. Mobil Solvancer is a solubilizing
agent that quickly dissolves deposits and varnish to help maintain
cleanliness of turbine bearings, seals and hydraulic systems. When
cooled, Mobil Solvancer maintains residual deposits keeping them
in solution to avoid re-adhesion, transfer of deposits, filter plugging
and oil line flow blockage events. It can be used with seals, paints
and other coatings commonly used in industrial equipment.
Siemens Energy has tested the compatibility and effectiveness of
Mobil Solvancer and concludes that it may be beneficial to add this
product to the oil to stop and even reverse the varnish effect. If
the customer wants to use Mobil Solvancer, an oil analysis must be
carried out to check whether the used oil meets the requirements
for an operating oil. If this is the case, Mobil Solvancer can be added.
In addition, Mobil Solvancer is approved for use in lube oil systems
of Everllence/MAN-ES turbomachinery.
Follow recommended dosing and maintain the viscosity classes
recommended in the machine’s operating manual.
