Letter of no objection by Wärtsilä Finland Oy

The head of Fluids Technology of the Wärtsilä Group, Kai Juoperi, demanded an analysis of pure XBEE to prove the safety of the product. This analysis has been performed by the DNV Petroleum Services on January 4, 2008.

The report clearly shows that XBEE Enzyme Fuel Technology does not contain any chemicals, alcohols, acids, metals or ashes. Consequently, the natural enzyme fuel treatment XBEE has been considered safe to be used in all Wärtsilä and related engines.

Wärtsilä Finland Oy has published a letter of no objection on May 16, 2008. This letter has been then renewed regularly, more recently on November 14, 2022.
