As your request we certify that since many time ago we are using the
fuel oil additive "rb bertomeu" beco F1/ASF and also de
Cleaner product "belim F" , both of them manufactured
and supplied by your company. The products are used in the Co-generation
plants which are managed by our Company and the obtained results ,
technical and economical, are as expected when we decided to use them.
In the plants where we are using regularly the additive "rb
bertomeu" beco F1/ASF , we are consuming two type of fuels ,
Fuel oil nº1 and Fuel oil nº1 BIA , and , in both cases , we have
detected big positive differences when the fuels are treated , from
another periods when the fuels were not treated or were treated with
additives from other different companies.
Our experience about the use of your fuel additive is applicable to
Diesel engines manufactured by Deutz and Wärtsilä .
We authorise the circulation of this letter as a reference for any
