Webinar Description: Renewable Energy is important for many reasons. To remain viable as an alternative energy source these technologies must run reliably and at the lowest possible cost. Lubricated machines such as turbines and gearboxes require proper oil care and management. In this informative webinar led by C.C. Jensen's Justin Stover, you will learn practical steps that will make Renewable Energy greener; by conserving precious resources and slashing O&M costs. Instructor: Justin Stover, C.C. Jensen, Inc. Justin Stover earned his degree in 2001 in fluid power technology. He has more than 10 years experience in helping end users and OEM's in the Wind industry implement, develop and deploy contamination control programs. He is certified by the International Council for Machinery Lubrication as a Level 1 Machinery Lubricant Analyst.

6. The Importance of Analysis and Filtration
THE IMPORTANCE OF CLEAN OIL AND IT’S IMPACT ON
RELIABILITY HAS BEEN KNOWN FOR DECADES
“Replacing 40-25µm filters by units rated at 3µm absolute is to
be recommended for gearboxes. Such action should lead to
improved reliability, longer periods between overhaul, cheaper
overhauls, and consequent reductions in ownership costs.
Times between oil changes, where relevant, should be
substantially increased.”

9. The Importance of Analysis and Filtration
Did You Know?
The estimated cost of an
oil change is $5,000 on a
Wind Turbine.
LESS USE
OF FOSSIL OIL
LESS TRANSPORTATION
LESS WASTE OIL
IMPROVED FILTRATION
IS ABLE TO KEEP THE OIL CLEAN
AND MAKE IT LAST LONGER

Take Away: No machine has ever failed because
the oil was too clean; What get’s measured
get’s done.
Question: What is the most important
parameter on your oil analysis test slate?

That’s the cleanest

“The oil at [our project] is the exact opposite of
the [clean] oil, its beyond filthy!! We should
have taken out disaster insurance on it…you
would not believe or want to see what comes
out of one of these when you turn it upside
down. Well, maybe you would. It was the most
disgusting, revolting lumpy stinky slime I’ve ever
seen come from the bowels of the gearbox.”

“Since [upgrading our filtration] our oil analysis has
showed considerable improvement, and our
gearbox has yet to have a single bearing
failure, vibration analysis alarm, or high-heat
signature. We are likely to save major repairs – that
may cost over $900,000”
