E28300 ARANJUEZ – Madrid – (Spain)
30th January 2001
certify that in the Ufefys co-generation plant, located in Aranjuez
(Madrid), we have been using “rb bertomeu” additives for fuel
oil regularly and without interruption since the beginning of 1996.
nearly 5 years of using these additives in our fuel oil, especially beco
F1/ASF, we are pleased to show our total satisfaction with the
technical and economic results obtained from the two DEUTZ engines, type
BV 16M 640, in the plant.
we have said before, the use of “rb bertomeu” additives to
treat fuel oil has given us a notable economic benefit through the basic
points which are a consequence of various actions on the process:
A saving in maintenance
due to the great reduction of corrosion in exhaust valves and no
corrosion in turbos and inlet valves.
An increase in the
service of the plant
due to the lower number of maintenance and cleaning stoppages, and an
increase in the TBO (time between overhauls) made possible by the longer
life of the exhaust valves.
long period of production that the plant has had using these additives
is a guarantee, as we understand it, of their quality for this kind of
on previous occasions, we authorise the use of this letter for reference
purposes for your products and services.
